Fabtech's new 4" crossmember systems utilize their proven heavy duty construction and design features found in their 6" systems but with less lift for use with 33" tall tires. These 4" systems feature high arched lower control arm crossmembers constructed of 1/4" thick steel for maximum strength. The Fabtech ductile iron steering knuckles retain the stock track width keeping tires under the fender for a clean appearance. Rear lift is accomplished with a block and u-bolt configuration. The Basic System includes front coilover spacers that utilize the factory Coilover shocks. Rear shock options include Performance or Stealth monotube shocks.This Part Fits: Year Make Model Submodel 2016-2018 Chevrolet Silverado 1500 Custom 2014-2018 Chevrolet Silverado 1500 High Country 2015-2018 Chevrolet Silverado 1500 LS 2014-2018 Chevrolet Silverado 1500 LT 2014-2018 Chevrolet Silverado 1500 LTZ 2015-2018 Chevrolet Silverado 1500 SSV 2014-2018 Chevrolet Silverado 1500 WT 2014-2018 GMC Sierra 1500 Base 2014-2018 GMC Sierra 1500 Denali 2014-2018 GMC Sierra 1500 SLE 2014-2018 GMC Sierra 1500 SLT
