CST 2011 - 2019 GM 2500HD / 3500 Upper Control Arm Kit # CSS-C2-21

CST Performance Suspension Upper Control Arm Kit # CSS-C2-21. This CST arm kit is designed to fit 2011, 2012, 2013, 2014, 2015, 2016, 2017, 2018 and 2019 model year Chevrolet Silverado 2500HD / 3500 and GMC Sierra 2500HD / 3500 series trucks. This is CST's latest design and features a ball-joint capable of operating at steeper angles than the factory joint. CST also changes the angle at which the ball-joint pocket is welded into the arm to eliminate bind when installed on trucks with altered suspension ride heights making them perform for use on trucks equipped with Torsion Key leveling lifts. The CST Ball joint is designed to hold up in extreme weather conditions which is helped with a billet cover plate and boot. The new OEM style bushings are designed to give you a quiet, no maintenance bushing for the lifetime of the vehicle. Lifetime warranty on complete arm including the bushings and ball joints!

CST is so proud of their new OEM style maintenance free bushings that they are offering a Limited Lifetime warranty on the bushings! The bushings are quiet and do a very good job at minimizing any road noise (vibrations) from being transmitted from the road surface and into the chassis.

Tire and Wheel Information:

This CST Upper Control Arm Kit is compatible with stock tires and wheels. If running a significantly wider (or more aggressive) than stock size tire on the factory wheels you may need to keep an eye on tire to arm clearance. If you are running aftermarket wheels with less back space than the stock wheels tire clearance will not be an issue.
