Chevy/GMC 1500 4WD Pickup Specially designed to offer improved offroad capability while maintaining on-road handling and comfort, these new 4" IFS system are FMVSS 126 (ESC System) compliant, improve ground clearance and allow more wheel fitment options than any other kit on the market.
At the heart of this BDS 4" IFS system are a pair of 1/4" thick laser cut high clearance crossmembers to maximize clearance and provide a solid mounting point for the OE lower control arms. These paired with the 3-piece heavy duty front skid plate system create a rigid subframe while adding protection for vital steering and driveline components. In place of the factory steering knuckles a pair of specially designed ductile iron replacement steering knuckles are supplied to maintain proper steering geometry for ESC system compatibility while also allowing a wider range of wheel fitment options to include factory 20" wheels. These connect to the factory steering with a pair of heavy duty replacement tie rod ends included in the kit. The front differential is repositioned with BDS's multipoint relocation bracket system tying into the frame and control arm pockets to further secure the front differential to keep CV axle angles at a minimum. Additional ride height on this particular kit comes from a set of top mounted steel fabricated strut spacers to mount onto the factory strut assemblies. A pair of BDS-branded sway bar drop brackets used to correct the operating angle of the factory sway bar as well as created a strong brace between the rear crossmember and the frame. Also supplied are new lower control arm cam bolts to allow alignment and a weld-in frame reinforcement plate for extra strength. In the rear lift blocks and longer u-bolts lift and level the stance and your choice of NX2 gas or FOX 2.0 performance series gas shocks are supplied to round out this kit allowing room for up to 35" tires to be installed. Check instructions for additional tire & wheel fitment combinations.
Choose between the custom valved NX² series or the Fox 2.0 series gas charged monotube rear shocks.

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.
