FOX 2.5 Coil-Overs

FOX 2.5 coil-overs offer next level performance for on-road comfort and off-road comfort capability. Tuned and ready to install right out of the box, these bolt-on 2.5-inch diameter coil-overs are built for abuse and packed with race-proven technology. They include a remote reservoir for additional fluid capacity to keep your shocks running cool so you can push the limits in the rough terrain.

DSC Adjustment

FOX 2.5 coil-overs are available with optional DSC (dual speed compression) adjustment to tune the high-speed and low-speed compression damping allowing for added control on-road with the ability to easily dial in more aggressive damping offroad. Tuning is a simple twist of the two clearly defined knobs with immediate feedback to dial it in for any terrain

HD Control Arms

Built for strength, performance and increased travel, these control arms are ready to bolt-in. The upper arms use 1.5" OD x .120-wall tubular construction with an indexed ball joint cup to correct the ball joint positioning allowing additional down travel and camber adjustment. The new lower control arms are built from high strength steel, fully boxed with internally gusseted. At the frame mounting ends are durometer-specific rubber bushings for maintenance-free operation while at the other end a quality greaseable ball joints for smooth, quiet operation and superior durability. Arms are finished in a durable black powder coat with a billet aluminum dust cap ready for installation right out of the box.

Rear Lift Option

Determine if your truck was manufactured with or without top-mounted overload springs on the rear leaf springs.

• 3" block - Will result in a slightly tail-low stance.
• 5" block - Will result in a level to slightly tail high stance, integrates a u-bolt flip kit with new spring plate.

Important Notes

1. A torsion bar tool is required to unload the torsion bars.
2. Requires frame bracket and differential modification.
3. Minor welding is required for coil-over mount installation.
4. Stock 17" & 18" wheels cannot be reinstalled.
5. Stock 20" x 8.5" wheels with 6" backspacing or less will fit with a max tire size of 35 x 12.50.
6. Models with two piece rear driveshaft may require carrier bearing drop kit (#121612).
7. Coilovers are preset for DIESEL engine models. The use of the coilovers on GAS engine models is not recommended due to providing too much lift. Available preload adjustment is typically not enough to achieve desired ride height.
8. Will NOT fit dually applications.
