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.

4-Link Conversion

Convert the factory stamped steel radius arms over to the BDS 4-link to optimize suspension geometry for better handling characteristics while adding strength and stability. This bolt-on upgrade utilizes high-strength 1/4-inch steel brackets that allow mounting of HD upper and lower control arms to correct axle positioning while limiting caster change throughout wheel travel.

BDS Glide-Ride Leaf Springs

Built to outperform, BDS engineered the Glide-Ride leaf springs into a multi-leaf progressive spring rate design that provides a smooth ride with any load. This is accomplished with an exclusive triple-stage leaf spring design where the main leaf pack is broken into two stages:

1. First, the primary three leafs are functional with no additional load in the vehicle for excellent everyday ride quality. As moderate loads are applied, the secondary leafs are engaged.
2. Second, if the truck is fully loaded, the bottom overload is engaged for maximum hauling capacity. This setup allows your truck to maintain ride quality unloaded without sacrificing payload.

Upgrading to BDS Glide-Ride leaf springs will reduce axle wrap and provide flexibility throughout the suspension cycle.

Important Notes

1. Exhaust modification may be required to clear the front driveshaft (gas only)
2. Front bumper spacer kit may be required to run 38"x15.50" tires
3. Although extremely rare, front driveline vibration may occur
4. If equipped with 2-piece rear driveshaft, a driveshaft alignment kit (#123406) will be required
5. Front driveshaft u-joints may max out at full droop. If so, a new front shaft will be required.
6. If equipped with a rear sway bar, #123009 is required.
7. U-bolts will not work on dually.
8. Front auxiliary shocks can be omitted from kit - the system can be used with C/O installed alone

BDS leaf springs are not intended for use beyond the truck's maximum payload capacity. Trucks equipped with overload springs will only have the capacity of a non-overload equipped truck. If heavy payload use is desired, supplemental rear airbags are recommended.
