Besides being ugly, the lower front end of your '99-'07 Chevy pickup does nothing for clearance and your off road approach angle. Clearance and approach angle are of great importance in off-road driving.
An inexpensive solution is a leveling kit for the front of your Chevy/GM 1500 and 2500HD truck. ORU leveling kits are the proper way to level your 1500 and 2500 series trucks. Cranking up the factory torsion bars and cogs overload the adjusters and limits suspension travel, creating a harsher ride and accelerating front-end wear. The ORU system uses special re-indexed torsion-bar adjusting cogs that level the vehicle without compromising suspension performance and Bilstein 5100 series shocks for ultimate ride quality and front end wheel travel. With this kit installed, you can use up to 33” diameter tires. Installation is straightforward and can be accomplished in less than 2 hours (excluding professional alignment).
