Extended Product Information:

The first objective of these a-arms was to improve strength and durability without sacrificing rigidity to keep these race-bred machines at the front of the pack. The design changes still retain all stock suspension geometry yet have been improved structurally to eliminate potential breakage points and slop at the hinge pins and caster blocks. The box-stock B44.2FT came with hinge pin holes with .005” (.13mm) of clearance in each hinge pin hole! That’s a total of .01” (.26mm) of slop (inside and outside hinge pins combined) before the vehicle ever ran! By tightening up these “loose” areas with our A-arms, the B44’s camber, caster and toe angles are locked in place while improving suspension performance and consistency at the same time.

The stock anti-sway bar pivot balls molded in the A-arms are .005” (.13mm) undersized. That leads to inadequate performance of the sway-bar system. Eliminating the molded ball entirely and replacing it with a more stout, machined pivot ball (not included – see “tech notes” below), with closer tolerances on the ball diameter became the best fix.

Each RPM A-arm for the B44 is molded in black and comes with a limited lifetime warranty against breakage. When performance counts and the goal is to get across the finish line, you can count on RPM to get you there!

Tech Notes: RPM A-arms for the B44 fit the B44, B44.1 & B44.2. Individuals wanting to run a sway bar system must use any standard 4.3mm ball stud such as Associated #6276. We recommend Associated balls studs for the most consistent diameter but any 4.3mm ball stud with a 4-40 x 1/4” thread will work.
