Show original supplier description
The BDS Suspension 124FS is a comprehensive 4-inch lift kit engineered to enhance the stance, performance, and capability of 1977-1987 Chevrolet and GMC 3/4 ton K20, K25, K2500, K2500 Suburban, K5 Blazer, and Jimmy models. This kit is designed for an easy, 100% bolt-on installation, allowing for clearance of up to 35-inch tires. Upfront, the kit features Glide-Ride leaf springs to achieve the full lift height and increase capacity, along with a new steering arm to maintain proper steering angles for improved handling. Precision-tuned NX2 nitrogen-charged shocks are also included for better control. In the rear, the kit utilizes high-strength cast steel lift blocks and add-a-leaf springs to create a level stance, complemented by a matching set of NX2 Nitro shocks. Important considerations for installation include potential exhaust modification to clear the front driveshaft. If your vehicle is equipped with a factory front sway bar, a drop kit is available separately. Additionally, if your vehicle came with factory front dual shocks, you will need to order two auxiliary shocks separately to replace them. Buyers should also measure their factory rear springs, as some 3/4 ton trucks came with a 52-inch rear spring instead of the common 56-inch spring. This kit accommodates 35x12.50 tires with 15x8 wheels and 3.5 inches of backspace.
