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

Built for diesel Chevy and GMC truck owners who need commanding ground clearance and a smooth ride without sacrificing load capacity. This 4.5-inch lift kit converts your 2500HD or 3500HD to FOX 2.5 coil-over shocks up front — a setup that handles heavy towing, rough terrain, and daily driving with the same poise. You keep full driveline geometry and factory proportions.

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 coil-over shocks — replaces the factory coil springs with adjustable dampening, letting you dial in comfort for empty or loaded runs.
• Lift coils — engineered to maintain ride quality and suspension travel across the full payload range.
• Caster-corrected upper control arms — preserves steering geometry and eliminates the need for costly geometry fixes down the road.
• Dropped pitman arm — keeps steering centered and responsive after the lift.

Out back

Four-link rear suspension with add-a-leaf springs handles the weight of a lifted 2500HD or 3500HD without squatting, keeping your truck level when towing or hauling.

Important notes

• OE wheels (17-inch and up) fit without rolling or trimming.
• Maximum tire size: 35 inches.
• Driveshaft does not require modification.
