Mazzulla Offroad Billet Upper Control Arm Kit # MZS-C1-4. 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 2019, 2020, 2021 or 2022 Chevrolet Silverado 1500 or GMC Sierra 1500. 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. Extended travel coilovers require a high quality aftermarket upper arm to get the maximum amount of suspension travel from the longer shock length. The Mazzulla upper control arm features large 1.25" uniball bearings that offer a lot more range of motion (with no binding) as well as an increased strength and longevity over the stock parts they replace. Mazzulla includes an O-ring equipped UniBall 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.

Mazzulla understands that one size does not fit all and designed their upper arms to offer a wide range of camber and caster setting options.The rod ends used at the arm pivots are adjustable and can be used to correct both the camber and caster after a lift or leveling kit has been installed. Most aftermarket control arms for GM trucks are a fixed length and cannot be adjusted... Mazzulla Billet Arms are adjustable and they may be exactly what you need to fix your out of alignment truck!
