Leveling Kit Basics
Understanding the basics of leveling kits helps you make better choices for your GMC Sierra AT4. A leveling kit changes the height of the front suspension. This adjustment makes the truck’s stance more even. Many truck owners want a balanced look and improved off-road capability. Leveling kits also allow for larger tires without rubbing issues. Knowing the basics can prevent common problems and costly mistakes.
Purpose Of Leveling Kits
Leveling kits raise the front of the truck to match the rear height. This corrects the factory “rake,” where the front sits lower. The even stance improves the truck’s appearance and performance. It also creates space for bigger tires, which help in off-road driving. Some kits improve ground clearance, reducing damage on rough trails. Proper installation is key to avoid alignment and handling issues.
Types Available For Gmc Sierra At4
Several types of leveling kits fit the GMC Sierra AT4. Spacer kits are common and simple. They add a block between the coil spring and the frame. Coil spring replacement kits swap the entire spring for a taller one. Strut extensions lift the front by adding spacers on top of the struts. Some use torsion keys to raise the front suspension. Each type offers different lift heights and affects ride quality differently.
Common Problems With Leveling Kits
Leveling kits are popular upgrades for GMC Sierra AT4 trucks. They raise the front of the vehicle to match the rear height. This creates a more balanced and aggressive look. Yet, these kits may bring some problems. Knowing these common issues helps owners decide before installing a kit.
Many users report handling and steering concerns after adding a leveling kit. The truck’s dynamics change due to altered suspension geometry. This can affect driving safety and comfort.
Handling And Steering Issues
Leveling kits shift the truck’s center of gravity forward. This shift can cause less stable steering. Drivers may feel loose or wandering steering at higher speeds. Tight turns might become harder to control. The altered angles of the suspension components affect wheel alignment. This often leads to uneven tire wear and poor road grip.
Increased Wear On Suspension Parts
Raising the front end places extra stress on suspension parts. Ball joints, tie rods, and control arms experience more strain. This can shorten the lifespan of these components. Some parts may fail earlier than expected. Regular inspection and maintenance become crucial after installing a leveling kit.
Impact On Fuel Efficiency
Leveling kits can slightly reduce fuel economy. Raising the vehicle increases wind resistance. The engine works harder to overcome this drag. Even small changes in aerodynamics affect mileage. Drivers may notice more frequent visits to the gas station.
Potential For Uncontrolled Oscillation
Uncontrolled oscillation, or “death wobble,” can occur more often. This is a shaking motion felt through the steering wheel. It happens due to the altered suspension and steering angles. The truck may shake on rough roads or at certain speeds. Fixing this may require additional suspension adjustments or parts.
Warranty Concerns
Installing a leveling kit on your GMC Sierra AT4 can change how your truck rides and looks. But it can also bring warranty concerns. Vehicle warranties protect you from repair costs due to defects or failures. Modifications like leveling kits may affect this protection. Understanding how your warranty works after adding a kit is important.
When Warranty May Be Voided
The warranty may be voided only on parts affected by the leveling kit. If the dealer finds the kit caused a failure, they can deny coverage for that part. For example, suspension or steering components that break due to the kit might not be covered. Other unrelated parts usually keep their warranty protection.
Parts Most Affected By Leveling Kits
Parts under extra stress from a leveling kit often include ball joints, tie rods, and u-joints. These parts change their angles and load after installation. Failures in these areas are common and may not be covered if linked to the kit. High-lift kits increase risk of damage to powertrain and drivetrain components.
Manufacturer-approved Kits And Coverage
Using a manufacturer-approved leveling kit helps protect your warranty. These kits meet GM’s standards and are less likely to cause issues. Installing them at authorized dealers also supports warranty coverage. This approach reduces the chance of denied claims due to modifications.
Extended Warranty Limitations
Extended warranties often have limits on coverage for modified vehicles. Many exclude repairs related to suspension or frame changes like leveling kits. Check your extended warranty terms carefully before installing a kit. Knowing these limits prevents unexpected repair costs later.
