6.5 Inch Lift Kit | FOX 2.5 Coilover Conversion | Chevy Silverado or GMC Sierra 2500HD/3500HD (01-10) | Diesel

Built for diesel truck owners who want serious hauling capacity with a commanding stance — this 6.5-inch lift converts your 2001–2010 Chevy Silverado or GMC Sierra 2500HD/3500HD to FOX 2.5 coilovers up front, unlocking smoother ride quality, better body control, and the geometry correction your heavy-duty frame needs under load.

Installed and serviced at Road Runner Wheels & Tires. Most kits go in the same day. Call (678) 400-6467 to schedule.

What you get up front

• FOX 2.5 Coilover Shocks — replaces the factory torsion bars with adjustable coilovers that deliver progressive spring rates, better bottoming resistance, and ride compliance over rough terrain or loaded payload.
• Front Coilover Brackets — engineered mounts that preserve caster correction and pinion angle so your driveline stays in spec and driveshaft vibration stays minimal.
• Lift Hardware & Spacers — precision-machined components that set your front axle exactly 6.5 inches higher while maintaining OE geometry.

Out back

Choose your rear setup: Block Kit adds 6.5 inches with steel blocks, ideal for work trucks running consistent payload; Leaf Springs upgrade delivers more progressive spring rate and handles dynamic load shifts better, preferred by owners towing heavy or running variable cargo.
