About this product
Improve the stance, performance, and capability of your 2011-2019 Chevy Silverado and GMC Sierra 2500 HD 4WD with this BDS 6.5" lift kit, with clearance for up to 37" tires. BDS uses a No Torsion Bar Drop System that mounts the torsion bars directly to the top of the lower a-arm to maximize ground clearance. Up front it uses torsion bar relocation brackets, high-arched 1/4" steel crossmembers, multipiece differential relocation brackets, heavy duty skid plates, CNC-machined ductile iron steering knuckles, sway bar links, bump stop extensions, stainless steel brake lines, and CV spacers. The rear uses replacement lift blocks, a u-bolt flip kit, and NX2 Nitro or FOX 2.0 Performance shocks.

Notes
- Torsion Bar Tool required to load/unload the torsion bars.
- 3" rear block kit recommended for dually applications; 5" rear block kit will not fit dually applications.
- Stock 17" and 18" wheels cannot be reinstalled.
- Stock 20" x 8.5" wheels with 6.18" backspacing MAY fit a max tire of 37x12.50 on certain sidewall profiles due to clearance at the steering knuckle and sway bar; a minimum 1/4" wheel spacer may be required. A wider tire will cause clearance issues with the steering knuckle.
- Factory dually wheels cannot be reinstalled.
- Models with two-piece rear driveshaft may require #121612.
- If minor front driveline vibration occurs at highway speeds in 4wd and the vehicle is used this way regularly, BDS recommends replacing the front driveshaft with a dual Cardan style driveshaft.
- Determine if your truck was manufactured with or without top-mounted overload springs on the rear leaf springs.
