IMCA Approved Metric Chassis Control Arms with Aluminum Cross Shaft

The factory stamped style front Metric upper control arms do not provide the strength and reinforcement necessary to survive the circle track racing lap after lap. Flexing and cracking are the norm with stock stamped steel Metric upper control arms, which can lead to catastrophic control arm failure and a bad wreck. No one wants that. A much safer and stronger alternative is a steel tubular control arm. The increased strength and rigidity of this style of front upper control arms mean repeatable handling with minimal wear and maintenance. IMCA understands this and is why they allow a tubular control arm as the spec piece in classes such as Stock Car. Now you can replace your aging or worn stamped steel control arms with these stronger IMCA upper control arms for your Metric chassis-based race car.

Made from 1-inch diameter .092-inch wall thickness steel tubing and featuring a reinforced 1/4-inch-thick ball joint mounting plate, these IMCA approved tubular steel front upper control arms include lightweight aluminum cross shafts. These aluminum cross shafts are a metal-on-metal greaseable pivot design and save two pounds of front-end weight per tubular control arm over our standard tubular control arm with steel cross shaft. The cross shaft is designed to mount to GM Metric chassis fitments with 6-7/8-inch mount spacing (or use our weld-on mount plate). We made the left arm standard 8.50-inch in length to maintain the factory suspension geometry, while we shortened the right arm to 8.0 inches to increase negative camber for circle track use. These are often used in conjunction with “tall” ball joints, and these arms use standard Metric arm K5208 ball joints. A steel cross shaft version is also available for those looking for absolute durability and longer service life.

These arms are light, well built, and provide a much better camber than stock. They are completely flat, so you can flip them over to use on the left side as well.

The control arms were a perfect fit. All machining and welds are excellent quality. Wall thickness is very good unlike most cheaper arms I've installed. These are not only some of the best quality control arms I've used, but also by far the most affordable.

What is the weight difference between this upper control arm and the upper control arm with the steel cross?

I have read these arms are intended for dirt G-body cars, but will fit an s10. Would running two rights (8" long) give me more negative camber on both sides compared to stock geometry?

Has any of the geometry affecting caster and camber been changed from stock on this product? I have added taller upper ball joints to my car (for autocross and street use) and am now having to run an excessive amount of shims with my stock A arms. Will these reduce the number of camber shims needed?
