- 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.

Improve handling and make your classic A-Body feel like a modern day muscle car by installing our P/N 4033 tubular upper a-arms. The relocated ball joint plate on these a-arms permits up to six degrees caster without excessive shimming. Expect improved steering feedback courtesy of increased caster and a precise feel due to the UMI built Delrin bushings. Features include greaseable, low deflection UMI designed and manufactured Delrin bushings, CrMo cross shafts, improved header clearance and polyurethane bump stops. These track-tested, jig built DOM a-arms are supplied with a durable gloss red or black powder coat finish which guarantees your performance parts stay beautiful on your street car, drag car, autocrosser or Pro-touring machine. For even more performance, check out the P/N 4033-1 which adds the benefit of a ½" taller ball joint for an improved camber curve and flatter contact patch.
- Polyurethane bump stops included.
- Premium ball joints installed.
- Increased caster.
