- Drive type. If your car is all-wheel drive, make sure the part is for all-wheel drive, not rear-wheel drive.
- Engine size. For engine parts, make sure the engine size on the product matches your engine.
- Transmission. Manual and automatic cars often take different parts.
- Body style. Sedan or hatch, two-door or four-door, cab and bed length on trucks.

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.
