Important Notes
- Removal of factory block required. Rear add a leaf is required for models equipped with factory 3-7/8" block for level to tail high stance. Single add-a-leaf kit # 113218 recommended for more level stance - Dual add-a-leaf kit # 113209 recommended for tail high stance. (Add-a-leafs do not apply to rear leaf spring equipped systems)
- If equipped with 2-piece driveshaft, a driveshaft alignment kit may be required.
- Although extremely rare, front and/or rear driveline vibration may occur.
- If equipped with rear sway bar, #123009 required.
- U-bolts will not work on dually.

FOX Performance Elite Coil-Over
FOX 2.5 Performance Elite shocks 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 shocks 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. The DSC adjuster adds remarkable versatility and precise tuning with a simple twist of either two adjuster knobs, offering 10 separate low-speed and 12 high-speed compression levels, with a black anodized aluminum reservoir to increase cooling efficiency.
Steering Correction
To optimize steering geometry once lifted, a forged drop pitman arm is used to minimize the steering angle and pair it with a heavy duty track bar drop bracket to keep them in phase through suspension travel while recentering the front axle.
