These billet machined uniball upper control arms are the ultimate performance, strength and durability gain for the front of your Chevy or Gmc truck. In a lifted application the upper control arms need corrected camber and caster geometry so that the factory alignment can be achieved. When adding aftermarket extended travel coilover shocks you will need more angularity in the upper control arm outer suspension pivot and these large 1.25" uniball bearings offer more clearance as well as an increased strength and longevity of the joint. The heim joint spacers and uniball pins are made using heat treated stainless steel and hold a tolerance .0005" for maximum fitment on bearing bores and factory upright tapers. These arms are machined in low volume using USA materials and the attention to detail are second to none. The combination of the upper control arm and a shock will yield improved handling characteristics, strength for offroad use and 40% increased wheel travel while maintaining the stock track width and suspension mounting locations. Ease of installation, high quality billet control arms and a race style shock absorber make this setup a great choice for anyone wanting to go fast in the dirt.
