Our good friends at JKS Manufacturing have released a brand-new variable-length control arm for the latest Jeep Wrangler featuring semi-bonded premium (non-poly) bushings. Length can be adjusted without the needs of any tools so you can dial in the exact caster and pinion angle you need for your ride. And each end rotates independently without binding, courtesy of stout rolled threads and an internal brass bearing that's said to be easy to lubricate. Both front and rear JKS control arms are available, they're built to outlast the life of your vehicle, and you can find out more about 'em here.
