Building on the tried and true 4" IFS systems these Performance Coilover Systems take ride quality, performance, and offroad capability to the next level with FOX coilover and shocks. At the heart of these systems are the replacement FOX 2.5 factory series remote reservoir coilovers available with the optional DSC (dual speed compression) adjustment. These coilovers join together with the BDS high clearance system to correct suspension, steering, and driveline geometry for unmatched quality and performance. Up front the kits utilize a pair of 1/4" steel high clearance crossmembers, replacement ductile iron steeling knuckles and multipoint differential relocation system to create a solid subframe and retain ESC system compliance. Along with that a 3-piece skid plate system adds protection of vital drivetrain components and the front of this kit is rounded out with CV spacers, heavy duty tie rod ends, longer sway bar links, and brake line brackets.
In the rear this 4" lift system a pair of a 3" coil spacers are used to lift and level the stance. The rear track bar is repositioned with a heavy duty bracket and support brace to recenter the rear axle, while longer sway bar links and bump stop extensions are supplied to optimize performance. Rounding out the rear are a pair of FOX 2.0 IFP performance gas shocks to improve rear dampening in horse off-road conditions while offering smooth performance on road.

No Fine Print Warranty
BDS stands behind its products and that’s evident by their No Fine Print Warranty. This no-BS warranty protects the original purchaser against breakage, bending, sagging, or any other usage failure. This “no fine print” lifetime replacement warranty extends to cover all BDS hard parts as well as bushings. Exclusions would be product finish and wearable items such as shock/stabilizer cylinders, tie rod ends and ball joints that would fall under the separate Limited Lifetime Warranty policy. Beginning February 1, 2020 all new kit purchases include the No Fine Print Warranty on bushings.

Limited Lifetime Warranty (for wearable items)
Wearable items include shock/steering stabilizer cylinders, ball joints and tie rod ends. BDS Suspension Co. warrants to the original retail purchaser that its these wearable parts are free from defects in material and workmanship for so long as they own the vehicle. Excluded from this warranty are the finish of the product. Defects in material and workmanship do not include such things as dented cylinders or bent rods caused by obvious side impact, rust or corrosion. A shock absorber is a wear item and over time will experience diminished damping resistance due to normal component wear. This is not a defect in material or workmanship and is therefore not warrantable.
