ICON 14-18 GM 1500 1-3in Stage 4 Suspension System (Large Taper)

This system features upper control arms with ICON's patented Delta Joint. The Delta Joint is a heavy-duty high angle ball joint that combines the durability of a ball joint with the performance characteristics of a traditional uniball. While the industry standard uniball does a great job of allowing the control arms of a vehicle to articulate with little bind, they do have an inherent weakness that leaves more to be desired when used in a daily driven application - exposure to the elements. The Delta Joint features a zinc plated housing providing the first layer of corrosion resistance, while a tough grease seal keeps potentially harmful elements out of the inner workings of the joint. Metal on metal construction and a greaseable design increase the longevity of the Delta Joint while at the same time allowing for noise-free operation. What makes the Delta Joint unique is that it brings the best of both worlds to ICON upper control arms with features that make it more robust than a uniball, and at the same time capable of greater angularity than a typical ball joint. 2014-2018 GM 1500 1-3" LIFT STAGE 4 SUSPENSION SYSTEM (LARGE TAPER) Ships in multiple boxes Fitment: Chevrolet Silverado 1500 Custom 2016 to 2018 Chevrolet Silverado 1500 High Country 2014 to 2018 Chevrolet Silverado 1500 LS 2015 to 2018 Chevrolet Silverado 1500 LT 2014 to 2018 Chevrolet Silverado 1500 LTZ 2014 to 2018 Chevrolet Silverado 1500 SSV 2015 to 2018 Chevrolet Silverado 1500 WT 2014 to 2018 GMC Sierra 1500 Base 2014 to 2018 GMC Sierra 1500 Denali 2014 to 2018 GMC Sierra 1500 SLE 2014 to 2018 GMC Sierra 1500 SLT 2014 to 2018
