Stock control arms are marginal at best. Bushing deflection combined with control arm flex creates erratic handling and inconsistent rear end stability when subjected to the added loads of performance driving. All of our control arms are TIG welded and utilize either greaseable 90 durometer spiral fluted polyurethane bushings or Teflon lined HD spherical bearings by QA1.
The CNC machined adjusters are made from 4130 chromoly and have rolled threads. All rod end spacers are 304 stainless.
You won't find better quality components. Additionally, our control arms retain the factory designed rear offset, a necessity others overlook resulting in split, binding bushings.
