When we last left off, we had our very clean and very stock 2015 Chevy Silverado 2500 HD 4x4 out in Simi Valley, California, at Powerhouse Performance, where Thomas Stevens and the crew installed the 6.5-inch front lift kit from BDS Suspension, complete with Fox 2.0 performance shocks. If you haven't seen that story yet, you can check it out here - Installing a 6.5-Inch Lift on a GM 2500HD.
The shadows were getting longer, but we all decided to persevere and knock out the rear of the truck—even though it took us well into the night. The rear kit basically consists of a block and U-bolt kit, except BDS features custom fabricated blocks that are available in 3-, 4-, and 5-inch heights, so you can fine-tune your stance any way you like; we went with the four-inchers. Also included are Fox 2.0 performance shocks for the rear. And finally, we opted for one other really cool upgrade.
BDS Suspension's Recoil system is a spring-loaded, full-floating traction bar engineered to improve traction and limit axle wrap without limiting suspension travel or decreasing ride quality. These traction bars allow you to tune the spring compression for optimal performance on-road, off-road, or towing. Recoil traction bars are fabricated from 2-inch OD x 3/16 wall steel tubing. Total length is 60 inches, and the bars mount to the vehicle using fabricated -inch steel brackets.
Once we got the back half of the 2500HD up to par and installed the Recoil system, we mounted up the Cooper Discovery SST Pro tires in 37x12.50R20LT to the polished 20x9 Guardians from American Force. Soon, we were on our way home. And the next day, we headed to the alignment shop to make sure this Silverado was headed down the road with laser-straight precision, but not before we perform one more mod in the form of a brake upgrade. Check out the final installment of this killer build very soon.
