BDS steps up the Chevy Silverado and GMC Sierra 1500 with this 4" suspension lift that clears up to 33" tires. Up front it runs top-mounted strut spacers, high-arched 1/4" steel crossmembers, multi-piece differential relocation brackets, and heavy-duty skid plates, with CNC-machined ductile iron steering knuckles and replacement tie rod ends to correct steering geometry and keep ESC compatibility. The rear uses a heavy-duty lift block, new u-bolts, brake line brackets, and precision-tuned NX2 Nitro or FOX 2.0 performance shocks.

Notes

• Requires frame bracket modification.
• 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 before mounting tires to ensure clearance to the steering knuckle / tie rod.
• All aftermarket wheels should be test fit before mounting tires to ensure clearance to the brake caliper. Some wheel profiles will not clear the caliper; test fit in stock condition before lifting.
• 2.7L Turbo models use the Diesel kit for proper skid plate fitment. If equipped with a mono-leaf rear spring, use part #UBT4064 (qty 4 required).
