We found some major issues behind your GMC Sierra’s leveling kit problem. Proper maintenance is the key to all success. However, we usually face some troubles that are listed below.

Difficulty While Driving

Your leveling kit may cause the car to run slowly. For example, you have a 2007 Silverado 1500. It’s whether you picked up an unsafe size and must either remove or fix the kit. Otherwise, your acceleration will lead you into problems.

Lack of Alignment

The GMC’s taller stance will upset the alignment. During the leveling phase, the casters need to be readjusted. Failure to align the front end leads to poor tire wear, and the car will likely pull to one side or the other while moving.

Remember that your front end will never be aligned if you don’t drop the mounting points. Furthermore, if you do not align the truck after installing the leveling kit, you will ruin your tires and cause the handling to be unpredictable.

Front Suspension Damaged or Worn Out

Forum says your front suspension will potentially wear out within 10,000 miles of the installation. A suspension system is considered a secured lattice of shock-absorbing vehicle parts. 

Generally. your suspension system and leveling kit should be compatible. The automobile’s higher stance makes servicing the suspension difficult. We noticed someone paid $6K to fix and replace the IFS suspension from the kit properly.

Too Much Fuel Consumption

The additional height may hurt the aerodynamics of the GMC Sierra, resulting in lower fuel economy. It is usual to lose MPG shortly after installing a level kit. 

The further you travel, the less MPG you get. Also, placing aggressive tires can lower your fuel efficiency. Therefore, experts advise against installing larger tires and resolving the issue immediately.

Shock Damage

Whenever you install a leveling kit, make sure you replace the shocks. Typically, shock absorbers feature several snap ring grooves that set the spring seat at various heights. Whether you have a GMC, Ford, Chevy, or Toyota, Shocks will be a lifesaver when installing a leveling kit.

For example, consider the GMC 2500HD leveling kit problem. In that situation, you should verify the shocks to see whether they are damaged. Shock problems will cause you to bounce up and down while driving over hills.

Tire Rubbing Issue

Another problem users have experienced is an issue with the leveling kit rubbing against the tires or suspension systems. As a result, whenever you spin the steering wheel, you may see your wheels rubbing.

It happens since you selected the incorrect size of tires and leveling kit, such as 35-inch tires on a 3-inch level kit. Therefore, you should select the 33″ tire rather than the 35″.

Clunking Noise

Observing a knocking or clunking noise while driving is a problematic event. But why this noise? It’s most likely due to a failure to tighten the sway bar end links. For an easy fix, check the given steps below:

  • Use a breaker bar to loosen the lug nuts from the wheels.
  • Secondly, jack up your truck with a floor jack and jack stands.
  • Next, remove the wheel.
  • Lastly, tighten the nuts when you have entrance to the sway bar.

The Steering Wheel Turns Left

GMC leveling kit problems can also cause your steering wheel to move to the left. This occurs when you overlook the stress your levering kit provides under the automobile. Lifting puts additional pressure on your suspension system.

The angle between the lower control arm, upper control arm, tie-rod, and CB axle becomes deformed whenever you lift the GMC. So, that’s the reason you should keep the alignment.

Lift kits provide substantially more ground clearance up to 10″ and a smoother ride. A raise package can transform your roadworthy vehicle into a monster truck capable of navigating the most difficult terrain.

However, we discovered some companies void the warranty if you install the level. Therefore, you should first talk about the policy of any company.
