Description
Part #: 13421
The direct-fit rear upper control arm adds strength, on-car adjustability and articulation flexibility to your stock-height or 'lifted' Wrangler. It features SPC's xAxis sealed flex joint receiver at the frame end to provide bind-free 'twist' during off-road articulation and an OE style rubber bushing on the axle end to reduce NVH (Noise Vibration Harshness). D.O.M. steel contruction and a forged link provide the strength required for large tires and aggressive gearing. The dual-threaded adjuster and jam nuts make rear pinion angle adjustments quick and easy without the need to disconnect the arm. California Residents WARNING
Self-lubricated and sealed xAxis joints are maintenance and hassle free. Easily adjust rear pinion angle 3 with Dual-threaded adjuster and jam nuts. Corrosion resistant coating provides superior protection from the elements.
