Read more 3.5" Front Suspension Lift Kit For Chevrolet Silverado 1500 and GMC Sierra 1500 Our 3.5" front suspension lift for Silverado 1500 and Sierra 1500 models gives you a more aggressive look and clears bigger tires. The front spacers in the kit were CNC machined from solid composites of aluminum and received a protective coating to prevent against rust and corrosion. 6061-T6 billet aluminum is specifically crafted with strength and durability in mind, providing heavy load support and improved off-road maneuverability. Each bottom strut spacer is meticulously engineered and precision CNC machined from High-Crystalline Delrin, for superior durability and corrosion resistance. Please note that the lift size does not equal the spacer thickness (which will be smaller), but once the installation is complete, the spacers will lift the full amount as advertised.

We believe quality is the most important aspect in building a kit and that's why each kit is made to specification using material sourced locally. Material is just as important as build quality. SUSPENSION LIFT KIT Our kit is a suspension lift as opposed to a body lift because when building a Lift Kit, we believe it should last for the life of your vehicle. Body lifts do NOT provide underbody clearance, so if you're serious about your vehicle and want a true lift, purchase one of our Suspension Lift Kits.
