FOX 2.5 Coilover Conversion Upgrade - 6.5 Inch Lift | Chevy Silverado or GMC Sierra 2500HD/3500HD (20-26) | Diesel

Built for diesel truck owners who demand premium coilover performance and precise tuning control, this FOX 2.5 Coilover Conversion Upgrade transforms your existing BDS 6-inch lift into a full coilover system with 6.5 inches of total lift. Factory torsion bars are gone — replaced by race-proven FOX shocks with remote reservoirs and 22 adjustable compression levels, giving you the responsiveness and cooling you need whether you're on pavement or pushing through rough terrain.

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

What you get up front

• BDS Tubular Upper Control Arms — 1.5" OD x .120-wall construction with indexed ball joint cups for camber correction and maximum down travel. Durometer-specific rubber bushings at the frame mounts; greaseable ball joints at the shock end for quiet, long-lasting operation. Black powder coat finish with billet aluminum dust caps.
• FOX 2.5 Factory DSC Coilovers — 2.5-inch diameter shocks with remote reservoir for additional fluid capacity and superior cooling. Dual DSC adjuster knobs deliver 10 low-speed and 12 high-speed compression settings — fine-tune your ride without tools.
• Bolt-on Brackets & Reinforcement — Heavy-duty brackets mount to factory shock locations. Weld-in support gussets reinforce upper mounting points for durability under load.

Out back

Rear suspension upgrades feature high-strength steel lower control arms — fully boxed and internally gusseted to match the front's geometry and handling precision. These work in concert with your FOX coilovers to deliver balanced, controlled articulation on rough ground.

Important notes

• Compatible with Chevy Silverado and GMC Sierra 2500 / 3500 HD diesel models (2020–2026).
• Control arm upgrades accommodate the new coilover geometry and travel requirements.
