FOX 2.5 Coilover Conversion Upgrade - 6.5 Inch Lift | Factory Series | Chevy Silverado or GMC Sierra 2500HD/3500HD (01-10) 4WD | Diesel

Built for diesel truck owners who want 6.5 inches of lift with adjustable damping and ride quality that doesn't sacrifice daily driving comfort. This FOX 2.5 Coilover Conversion replaces your factory coil springs with remote-reservoir coilovers tuned for the weight and torque of 2500HD and 3500HD diesel trucks. You get ride adjustability, better articulation, and the geometry correction that keeps your truck handling planted on-road and off.

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

What you get up front

• FOX 2.5 Remote Reservoir Coilovers — precision-tuned for diesel weight and torque, with independent damping adjustment so you dial in comfort or performance to match your mood and load.
• 6.5-inch lift height — clear sight lines, room for bigger rubber, and corrected caster geometry to keep caster and camber in factory-friendly ranges.
• All mounting hardware and brackets — engineered for 2500HD and 3500HD frames (01–10, 4WD diesel only).

Important notes

• This kit is engineered for 2001–2010 Chevy Silverado and GMC Sierra 2500HD/3500HD 4WD diesel models only — verify your chassis and year before ordering.
• Verify your current tire size and sidewall clearance; larger tires may require trimming or offset adjustment to avoid rub at full articulation.
• Remote reservoir mounts require factory routing; confirm exhaust and heat-shield clearance with your installer.
