The BDS Suspension BDS1803FSR 6-inch snap-ring coilover suspension lift kit for the GMC Sierra 1500 truck with a diesel engine allows for the fitment of up to 37-inch diameter tires, providing a great off-road look. Featuring Fox 2.0 performance series coilovers that retain the factory coil spring and top plate. These Fox 2.0 Coilovers feature a machined 6061 T1 aluminum body and are designed to enhance ride quality and handling in both on-road and off-road conditions.
This lift kit also features 1/4-inch-thick steel, laser-cut, high-clearance crossmembers designed to provide maximum clearance and a rock-solid mounting point for the factory lower control arms. Three-piece heavy-duty front skid plates connect the cross members, protecting steering and driveline components. Correct steering geometry is maintained using new ductile iron steering knuckles that keep the ESC system compatibility, along with tubular upper control arms. CV axle angles are minimized using a multi-point front differential relocation system. The rear end is lifted using 5-inch-tall axle blocks (replacing 2.5-inch factor blocks) with extended U-bolts.

Important Notes
Does NOT fit gas engine models
Requires frame bracket modification
Will not fit Adaptive Ride Control (ARC) equipped models
Factory 17" and 18" wheels cannot be reinstalled due to tie rod end interference, stock 20" wheels can be reinstalled
17" Wheels with 4.5" backspacing should be test fit prior to mounting the tire to ensure proper clearance to the steering knuckle / tie rod
All aftermarket wheels should be test fit prior to mounting the tire to ensure proper clearance to the brake caliper. Some wheel profiles will not clear the brake caliper. These can be test fitted before the vehicle is lifted in a stock condition
NOTE: This kit is NOT COMPATIBLE with vehicles equipped with rear composite mono-leaf springs. The mono-leaf is easily identifiable – the U-bolt is round/circular around the top of the leaf spring. This kit only works with vehicles equipped with traditional steel leaf springs – identified by ‘square’ U-bolts.
