| Suspension Arm Series |
These direct-fit control arms add strength, and articulation flexibility to your stock-height or ‘lifted’ Wrangler. They feature SPC’s xAxis™ sealed flex joints to provide bind-free ‘twist’ between the frame and axle during articulation and O.E. ‘Clevite’ bushings for long service life and reduced N.V.H. Main tubes are D.O.M steel to provide strength for large tires and aggressive gearing. Bent arms provide additional clearance for taller/wider tires.
