This kit includes one set of Boxed lower control arms and one set of on-car adjustable upper control arms, "Ultimate Arms". Both items are direct replacements of the OEM setup adding strength, ride improvement, and rear end adjustment. The lower control arms feature grease-able polyurethane bushings, reinforced sway bar holes, and a powder coat finish. The upper "Ultimate Arms" feature on-car adjustability with right and left hand threads, 4140 high strength Chrome Moly adjuster, and a QA1 Teflon lined spherical rod end. The upper control arms provide the best and easiest way to adjust pinion angle for suspension tuning. Each item is CNC machined for precise tolerances and accuracy. In addition, the QA1 Teflon lined rod end helps eliminate rear end bind, while the 4140 Chrome Moly threaded tube adaptors and heat treated adjuster offer added durability.
Includes boxed lower arms and on-car adjustable uppers for strength, ride quality, and rear end tuning. Lowers use poly bushings and powder coat; uppers feature QA1 rod ends, Chrome Moly adjusters, and easy pinion angle adjustment.
