MORE INFO:

RPM A-arms are significantly beefier than their original 6S version A-arms. Lower A-arm support beams are 30% thicker while upper A-arms are more than 22% thicker. The added thickness not only improves durability and strength, it also reduces flex. Less flex equates to more predictable suspension performance and handling.

On the lower A-arm, they added a second shock mount hole further outboard. This additional position provides a lower profile suspension set-up. The shocks lay down a little further, dropping the ride height for a lower center of gravity. A lower center of gravity equates to higher corner speeds.

As for the upper A-arm, they eliminated the caster spacers. This gives room to widen the arm at the inner hinge pin mount. The extra width creates more of an “A” shape, stabilizing the upper A-arm. A more stable A-arm improves steering and suspension performance while adding strength and durability.
