BDS Suspension 4" Suspension System Chevy/GMC 1500 4WD
Fitment2014-2018 Chevrolet, GMC 1500 4WD
BDS Suspension 4" Suspension Lift for the new 2014-18 Chevy/GMC 1500 4wd.
This new 4" system is built with all the same features and benefits of the 6" version. Full replacement 4" struts give the proper ride height in the front and the rear kit provides a 4" block to replace the factory 1.25" block. Like the 6" version, this system is FMVSS126 compliant. This new suspension system utilizes the tried and true high-clearance IFS suspension design that has made BDS the preferred suspension lift for the 1/2 ton GM trucks. At the heart of the new lift are the ductile cast iron replacement steering knuckles and high-clearance, full width lower control arm crossmembers. These components establish a suspension geometry that not only performs well on and off road but is compliant with the factory traction control systems. The suspension also works seamlessly with the newly redesigned electric power steering system that is standard on the new 2014-17 models. The front differential is relocated for proper angles at the CV axles and allowing for the use of the stock front driveshaft. A 3-piece differential drop system keeps the differential secure and the 3-piece front skid plate system keeps the underside protected on those offroad excursions. Full replacement front struts provide the lift in the front. Replacement front tie rod ends and sway bar links round out the front system. In the back, a block and u-bolt setup levels the rear with the front. For the ultimate performance package, the option for front Fox Coilovers with rear Fox 2.0 shocks is available.
*IMPORTANT*: GM is producing several knuckle/control arm configurations in 2014-2017 models trucks. Cast Steel control arm equipped models will require the "Cast Steel Control Arm" kit. Stamped Steel and Aluminum control arm equipped models will require the "Aluminum Control Arm" kit. Be sure to verify which factory control arms your truck has before ordering by referecing our help images when customizing your kit.
