How do I lower the suspension on my truck?
Truck owners frequently lower their vehicle’s suspension system by a few inches to give it a sporty appearance, or they go overboard and lay the frame flat to make a crazy custom show car.
A full-size or midsize pickup can be lowered in a variety of ways that change how it looks, handles, tows, and how much cargo it can hold. To help you better grasp the methodologies and what works best for the appearance and performance you want to achieve, we’ve described the most popular approaches and best practices.
By providing a full kit, manufacturers make it simple to lower your car. In this illustration, new leaf springs, shackles, and hangars are used to create a four-inch rear drop and a two-inch front drop with coil springs.
One of the best ways to lower your truck’s suspension by up to two inches is using an aftermarket set of coil springs. Check for a complete kit from the same manufacturer if your truck’s rear coils. To prevent spring sag over time, using progressive-rate springs manufactured of high-quality steel is the best option. Additionally, certain performance coils will lessen the stance by one and a half to two inches while enhancing handling.
Although it may seem like a less expensive option, cutting your factory coils will modify the spring’s compression rate and cause a bouncy ride, so it is not advised. It might not be wise to use a spring that lowers the ride height by more than two inches. When you need mild lowering, the correct coils will provide a smooth ride and won’t compromise the pickup’s total load capacity.
When greater lowering is necessary, coils can be used in combination with other lowering products.
Drop spindles are extremely common. This method can also be used to lower a few four-wheel-drive automobiles.
Drop spindles are probably one of the greatest ways to correctly lower your car by two or three inches without degrading the ride or suspension geometry from the factory. A high-quality spindle from a recognized manufacturer is worth the extra money because less expensive spindles have a history of cracking and shearing. Up to four inches of drop are possible when using drop spindles in conjunction with a two-inch lowering coil.
Another excellent way to correctly lower the front end of your truck is to use lower control arms. The lower coil spring pocket lowers the ride height of the car while leaving the rest of the suspension in place. For a four-inch front drop, these can be used in conjunction with lowering springs.
The factory wishbones in the front of your truck have been replaced with tubular upper and lower control arms. A deeper coil spring pocket will be present in a new lower arm. By doing this, the car is effectively lowered by two to three inches while maintaining optimum ball joint angles and a comfortable ride.
The lower control arm spring pocket shouldn’t be lower than the vehicle’s scrub-line, which is the lowest point on the car that will make contact with the pavement if the tire blows, if you plan to utilize low-profile tires.
The negative camber (top of tire points inward toward the body) that develops when the car is lowered will be remedied with a new upper A-arm. For optimal operation and suspension alignment, both matched sets of arms are required. They are frequently used in conjunction with shorter coil springs, air springs, and/or drop spindles to make your truck even lower.
There are numerous kits available for airbags or air springs. This one lowers the rear five to six inches by fastening to the axle and truck frame. Other mechanisms can be modified to fully lower the car to the frame.
For lowering a vehicle, air springs or airbags have special benefits. They may be placed almost anywhere, front or back, and when deflated, they create a very low stance. To drive the vehicle at a standard ride height, they can be inflated using an onboard compressor and a series of actuators, switches, and hoses.
The most options for a moderate to high descent are air springs. The factory coil springs in the front and leaf springs in the back are typically all that need to be replaced. Extreme lowering, in which the truck rests on the frame, calls for more specialized work and ought to be left to a pro. Setting a standard ride height for driving and aligning the vehicle at that height are two of an air spring suspension’s most crucial components. This will reduce the wear on tires and suspension parts.
Air springs can be installed into specially made A-arms in the front to lay the frame on the ground, depending on how low you wish to go. The rear suspension and frame can be laid on the ground by using a special rear air-spring structure that extends through the bed. Due to all of this, your vehicle will appear fantastically customized, but its ability to carry freight may be completely lost. Only if you’re thinking of building a show-winning car should you do this.
Hydraulic systems, made popular by lowriders, function similarly to air springs but fill solid cylinders with hydraulic fluid instead of the truck’s coil springs, shocks, and leaf springs. To function properly, this system needs a complex network of switches, solenoids, hydraulic lines, a tank, and a hydraulic pump. Due to the extensive cutting and welding, you should contact a reputable bespoke installer. Any capacity for hauling or moving cargo will be lost when using hydraulics.
Eye Hangars for Leaf Spring The majority of vehicles have leaf springs in the back because they can support more cargo. To lower the rear by 1.5 to 2 inches, many truck owners swap out the factory leaf spring mounts, commonly known as hangars and shackles. The factory shackles must be removed from the frame using drilling or cutting, and new ones must be bolted on. This approach is quite effective and is frequently used in conjunction with other items to create a lower stance. Because you’re still utilizing the factory spring, you won’t lose any of your vehicle’s towing or payload capacity, and this method also works excellent to level up the ride of your truck from front to back.
Dropping the back of your truck by lowering the leaf springs is a terrific idea. They produce a fantastic ride but at the expense of some of the total load and tongue weight capacity.
You can purchase leaf springs for the back of your truck to lower the ride height by two to three inches. The rear can drop four inches if those springs are coupled with new lowering spring eye hangars. These springs perform well to provide a comfortable ride because they have significantly less arch. The disadvantage is that they often don’t have a helper spring and have a lower total cargo and tongue weight capacity because fewer leaves are employed in the spring. But many truck owners may lift the back of the truck to make up for a large load or trailer by using an airbag helper spring that sits on top of the leaf spring to recover part of the lost cargo capacity.
For leveling or difficult applications, lowering blocks are frequently used. The best blocks are composed of steel and ought to have a shim to adjust the pinion angle of the differential.
One of the most common ways to lower the back of pickup trucks by one to three inches is with blocks. Leaf spring blocks are frequently included in lowering kits and are placed between the axle and the leaf spring. The ideal blocks to use are made of steel and have a pinion angle correction built in. They resemble a wedge more than a square block, or wedges can be added to the blocks to produce the right pinion angle. In most cases, leaf spring hangars and blocks are combined to lower the back of the car by up to four inches. Use premium U-bolts while lowering with blocks to avoid any problems.
Turn Kits Flip kits are frequently required to give enough travel and clearance between the axle and the frame for extreme rear lowering of five to eight inches. They turn the leaf spring and axle so that the springs are on top of the axle instead of underneath. A proper, high-quality flip kit will contain an axle locator that places the rear axle slightly forward and preserves the differential’s correct pinion angle geometry.
For increased axle up-and-down travel, the majority of flip kits additionally call for C-notching the frame’s rear section. A steel frame-support bracket that should be drilled and fastened into place reinforces the notch. Most truck frames are made of tempered steel, which welding frequently weakens. Axle and leaf spring flipping necessitates taking into account shorter shocks or shock extensions. These maintain the shocks at a more vertical angle for improved performance and a more comfortable ride.
Vibrations can happen when a center carrier bearing for a two-piece driveshaft is used by many trucks. Many flip kits include a spacer to lower the center carrier bearing, which sets the driveshaft at the correct angle, to solve this problem.
With a C-notch on the frame, this Dodge is an extreme example of a custom airbag system. Truck’s frame may now rest on the ground thanks to this.
Here are some of the more well-known techniques for lowering your truck among the many options available, to help you choose which might be the most practical for your situation:
Many manufacturers provide entire systems that eliminate the need to guess which parts to install to lower your pickup. The ride will be better by using shorter shock absorbers or shock mount extensions. A set of performance anti-sway bars may be helpful if you’re interested in performance handling. Also take into account the tire’s appropriate load rating. Various tire manufacturers make lower-profile tires that will go well with your lowered pickup and have the right load rating for a safe ride because trucks are still very heavy.
Does lowering a truck change the way it rides?
A common approach to personalize your vehicle is to lower it so that it is closer to the ground. When done correctly, it has a wonderful appearance and improves handling capabilities. If done incorrectly, it may impair handling, drivability, and traction, decrease tire tread life, and even harm certain components.
Benefits
A lowered suspension makes it easier for a driver to be acutely aware of how their car behaves on various surfaces since greater vibrations from potholes in the road surface are transmitted through the steering wheel.
With this arrangement, you need extra firm springs to prevent your vehicle’s front or rear from bottoming out over bumps or depressions. Many people would rather have this kind of driving experience than, say, a cushier ride in a premium vehicle.
Because of the lower center of gravity, there is significantly less lean when a vehicle makes a quick turn. The portion of the car that is outside a turn maintains a better level with the interior. This enables an automobile to act more rapidly and responsively during a turn.
Being nearer to the ground also results in better response, more stability, and grip at high speeds. When you hit the gas or brakes hard, less weight is transferred because lowering means getting firmer springs. You can benefit from quicker acceleration and stops as a result.
Vehicles that are lowered are more aerodynamic. Less air is striking the tires and wheels (that are not streamlined shapes). These cars are speedier as a result. Additionally, some owners of low-stance automobiles report better gas mileage. However, too much lowering of a vehicle will result in more wind resistance.
Vehicles with lower centers of gravity are less likely to flip over when turning.
When you lower a car, you often mount a set of plus-sized wheels and tires on it. These tires offer less roll around corners, shorter sidewalls, and a wider contact patch (which maintains more rubber in touch with the road).
Custom wheels and a lowered suspension are attention-getters for cars and trucks. It stands out in a crowd because of its more aggressive and performance-focused appearance.
Drawbacks
You may be less concerned about the ride comfort of a lower suspension if you and your passengers are used to a suspension that is softer and softens hits like bumps and potholes. As a result of being nearer the pavement, you might also hear more traffic noise.
Your enemy on rutted, rocky, washboard, and potholed roads will be the reduced clearance.
Your wheel-tire fitting geometry changes as you descend. If it’s done incorrectly, your automobile could have alignment issues that cause excessive or premature wear patterns.
Even a half-inch lower suspension might cause issues while driving over speed bumps, small potholes, or in tight turns. The front of your car might strike the pavement if you start up a driveway or ramp, drive over the lip of a parking garage, or cross a curb. Components underneath the automobile, such as the oil pan and exhaust system, are vulnerable to severe damage if they come into contact with the ground.
You could need a flat bed if you ever need a tow truck. If not, there can be an issue with the vehicle’s back body dragging on the ground.
Incorrect or excessive lowering might result in the wheels, tires, or suspension and steering components coming into contact. Additionally, it could result in tire rubbing when making turns or travelling over bumps.
If you have a flat tire, you can discover inconveniently that there isn’t enough room to get the unit beneath the frame of the car.
It might be costly to maintain proper alignment and use high-quality components. The likelihood that you’ll need extra parts increases as you descend. For instance, you should expect to spend $1,000 or more if coilovers (coil spring over shock) are a part of your new configuration.
To find out whether 1) the manufacturer advises against lowering your car or 2) whether lowering your car will invalidate or negatively affect whatever warranty coverage you presently have, you should examine both your owner’s handbook and any manufacturer’s or aftermarket warranty.
Know This Before You Modify Your Suspension
- You could need to reduce a lot less than you think if higher performance is what you’re looking. It’s simple to miss the mark and worsen your penalty. Get professional assistance to ensure that parts like struts and springs can maintain the proper angle for the tires.
- When it comes to shocks, struts, or other parts, don’t skimp. You are adjusting the balance and structure of your car. Don’t take a chance on broken components.
- Your insurer can refuse to cover a claim for damage if you modify your car in a way that isn’t permitted for the road. Ask your agent if your premiums will increase or your policy terms will change before you customize your ride.
- Extreme aftermarket wheel-tire combinations or suspension modifications may cause steering, suspension, or drivetrain issues that are not covered by your car’s warranty. Before installation, determine whether the alterations you’re considering may lead to rejected warranty claims.
- After you lower, get an alignment to assure the optimal handling and tire longevity.
- Be cautious as you adjust to how your new arrangement works. Your car may steer a little differently and won’t be able to absorb road shocks as well thanks to the considerably stronger suspension. A loss of traction could result from an abrupt hard brake or a tight bend on a rough road.
Make sure you’re not putting together a setup that is hazardous or will interfere with other car systems if you modify your vehicle’s OE (original equipment) suspension. It involves striking the correct balance between safety, performance, aesthetics, cost, and driveability, just like with many aftermarket modifications. Visit your nearby Les Schwab for assistance.
