Steel Upper A-Arm Replacement for the Porsche® 928


Lightweight, Strong, and Rebuildable!

Application: Porsche® 928 1986.5 - 95 all

Background: Porsche® changed from cast to forged upper A Arms in late '86 and the new upper arms were not designed to be serviceable. When your upper ball-joint wears out, they cannot be rebuilt. We do have a few professionally re-manufactured units at $419.00 each. This part is also still available (for the moment) from Porsche® and the suggested retail price on that is $926.00 EACH. You need two.

Description: Now 928 Motorsports offers an all-new replacement for the 928 lover - our Late-Model Steel Upper-A-Arm. Using the same techniques we use for race car suspensions, we created a jig with the exact dimensions of the Porsche® 928 arm, and have produced an all-steel welded unit with a high-grade greaseable ball joint in it. This is a bolt-in piece that requires no modification to your 928, and it is serviceable if need be at any time in the future.

Performance: The spherical ball joint we use provides more accurate placement of the top spindle than the common production ball-socket joint, and the solid bushings at the rear guarantee exact camber adjustment without the variables caused by the stock rubber bushings. These even out-perform a stock a-arm fitted with with polyurethane bushings, yet move with less effort through the suspension arc . Weight savings = 1.2 lbs of unsprung weight per side.

928 Motorsports Quality: Our part features a steel crossbar, oil-impregnated bronze bushings, and zirk fittings at the back. At the front, it's equipped with a premium removable and rebuildable ball joint for accurate camber placement and long life. The ball joint can be unscrewed and replaced completely without removing the A-arm. Silicone dust boots included.

Price is per PAIR, enough for both sides of one car.
