FOX 2.5 Coilover Conversion Upgrade - 6.5 Inch Lift | Chevy Silverado or GMC Sierra 2500HD/3500HD (11-19) | Diesel

Built for diesel truck owners who demand smooth, controlled suspension over rocky terrain and heavy towing. This FOX 2.5 coilover conversion replaces your factory coil springs with performance dampers tuned for the weight and power of a 6.5-inch-lifted 2500HD or 3500HD. You get 6.5 inches of lift, improved off-road articulation, and the adjustability to dial in your ride — whether you're hauling or exploring.

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