What is a leveling kit? The simple answer is a leveling kit is designed to level out the front of your truck, SUV, or Jeep to match the height of the rear of the vehicle, giving the vehicle a level stance. Most trucks, SUVs, and Jeeps come from the manufacturer with a slight rake. Rake is when the front end of the vehicle is lower than the rear. Manufacturers release their vehicle with a rake to level out once weight is added to the rear of the truck. When adding weight, the rear suspension will compress and level out with the front or slightly lower to optimize towing.
