BDS Suspension 3 Inch Lift Kit, FOX Coilover Conversion, Chevy Silverado or GMC Sierra 2500HD/3500HD (20-26) Diesel, 4WD, Block Kit Without Factory Overload, FOX 2.0 Performance Series Rear Shocks
PN. BDS1829FPE
A BDS Suspension lift kit raises your truck or SUV to make room for larger tires and add ground clearance, while correcting the geometry that matters for a good ride and safe handling. Each kit is engineered for the vehicle it fits, with components chosen to restore steering, driveline and suspension angles after the lift. BDS kits are offered with a choice of shock packages, so you can match the ride to how you use your vehicle, from daily driving and towing to trail and off-road use.
This part number is configured with rear lift: Block Kit Without Factory Overload; rear shock: FOX 2.0 Performance Series Rear Shocks. Front lift: 3 in (coil-over). Rear lift: 0 in or 2 in (block, stock). Clears tires up to 35 x 12.5. Recommended tire and wheel setups: 35 x 12.5 tires on 17 x 9 wheels with 4.5" to 5.5" in backspacing; 285/75 tires on 17 x 9 wheels with 4.5" to 5.5" in backspacing. Estimated installation time is 9.5 hrs, rated difficult. Installation notes: Models with two-piece rear drive shafts will require a carrier bearing drop kit. (BDS121612); Requires frame bracket modification and minor welding; Disassembly/assembly of the factory torsion bar system requires the use of a special unloading tool; The GM specified tool # is CH48809; Compatible with diesel models ONLY. Works with standard or AT4 diesel models. The use of the coilovers on GAS engine models is not recommended due to providing too much lift. Available preload adjustment is typically not enough to achieve desired ride height; Some minor trim will be required with certain wheel/tire combination. This is normal with most aftermarket tire/wheel fitment on Chevy/GM trucks. Trimming will normally include the bottom edge of the inner fender shrouds and/or lower corner of front bumper valance. As a rule of thumb, deeper backspacing and shorter/narrower tires will reduce/eliminate trimming required. Further trimming tips are included at the end of this instruction sheet; Dually Models will require aftermarket 20" wheels with a max tire size of 285/60/20; Factory 17", 18" and 20" wheels cannot be reinstalled due to upper control arm clearance; Coilover coil has a large amount of preload, a coil spring compressor must be used to remove the coil from the coilover. Failure to use a coil spring compressor may result in death or injury; Do NOT increase coilover preload; For replacement ball joints use service kit BDS081203. Ball joints are directional and must be installed with the "dot" facing either inward or outward on the vehicle, otherwise damage may occur; Increase of 1" of track width per side (2" overall) is done to create a better travel range of the suspension to allow more droop travel from ride height along width helping the coilover clear the frame components.
