Overview

The Superlift 8" Suspension is a true 8-inch lift kit designed for Chevy Silverado and GMC Sierra 1500 trucks. It provides the proper geometry correction needed for an 8-inch lift, unlike kits that achieve height with taller spacers.
Show original supplier description
The Superlift 8" Suspension lift kit is engineered to provide a true 8-inch lift for the Chevy Silverado and GMC Sierra 1500, allowing for the fitment of 35-inch tires with a wider profile. Unlike other kits that may achieve lift through taller strut spacers, this system utilizes steering knuckles and control arm crossmembers to ensure proper geometry correction for the full 8-inch increase. This kit is designed using OE data files to mimic factory components, aiding in installation and compatibility. Components like the brake lines and front sway bar are relocated to prevent binding during suspension travel. NOTE: This suspension kit does NOT fit 2007-2016 Chevy Silverado’s and GMC Sierra’s with OE CAST Steel Control Arms. It also WILL NOT work with any late model GM Truck or SUV equipped with MAGNERIDE from GM. Additionally, this kit does not fit Trail Boss models and will not work with stock wheels. It is designed for 2014-2019 Chevy Silverado/GMC Sierra 1500 4WD models equipped with OE aluminum or stamped steel control arms. Proper tire and wheel fitment is crucial; while a 35-inch tire is supported, manufacturers' dimensions vary, and fit-checking is recommended prior to purchase. Installation may require specialty tools and extensive modifications, and professional installation is advised for those without significant mechanical experience.
