Mazzulla 2007 - 2016 Silverado & Sierra 1500 Billet Upper Arm Kit # MZS-C1-2B

This Mazzulla Offroad Upper Control Arm kit is designed for use with 2007 - 2016 Chevrolet Silverado 1500 and GMC Sierra 1500 series trucks. This arm fits both the 2wd and 4x4 models equipped with the factory Cast Steel Suspension. This Mazzulla Upper Control Arm is designed only to work with the factory GM Steering Knuckle or any aftermarket steering knuckle or lift spindle that uses the same factory size upper ball-joint taper. Basically, if you are running a lift or leveling kit and currently have a factory upper control arm on your vehicle now this MZS-C1-2B should be a direct bolt-on replacement.

Mazzulla Offroad Billet Upper Control Arm Kit # MZS-C1-2B. These arms are machined in low volume using USA materials and the attention to detail are second to none. Mazzulla control arms start off as solid billets of high quality 6061 Aluminum and are machined by Mazzulla Offroad in-house in the USA. Mazzulla Billet Uniball upper control arms provide the ultimate in performance, strength and durability for the front suspension of your 2007, 2008, 2009, 2010, 2011, 2012, 2013, 2014, 2015 or 2016 Chevrolet Silverado 1500 or GMC Sierra 1500 equipped with the factory Cast Steel suspension. After a lift or leveling kit has been installed an aftermarket upper control arm is usually needed to correct the camber and caster geometry so that the factory alignment can be achieved.

If you have installed aftermarket extended travel coilovers the factory upper arm ball-joint can bind at full droop (rebound) and can limit your suspension travel which reduces the on and off-road performance of your truck. The Mazzulla upper control arm features large 1.25" uniball bearings that offer more range of motion (no binding) as well as an increased strength and longevity over the stock parts they replace. Mazzulla includes a cover to reduce wear and tear on the UniBall by helping to seal it off against the elements. The provided Heim Joint spacers and Uniball taper pins are machined using heat treated Stainless Steel and hold a tolerance .0005" for precise fitment on bearing bores and in the factory upright tapers.
