RPM - RPM70742 - REAR A-ARMS BLACK T4 SC10

RPM SC10, SC10B & T4 A-arms were designed to solve critical durability issues stemming from stock rear A-arms. Our SC10, SC10B & T4 rear A-arms are designed to withstand some serious abuse!

Our A-arms are over 25% thicker around the hinge pins than the stock versions which translates into pure RPM muscle to help eliminate damage during those “Wow, did you see THAT crash!” moments. Other design improvements include angled leading and trailing edges of the A-arms, which help the A-arms transition up and over objects much better than the blunt surfaces of the stock arms.

We also focused on the hinge pin retaining system used on the stock A-arms. Using a small screw hole so close to the hinge pin like the stock arms do weakens the A-arms. We moved the hinge pin retaining screws in-line with the hinge pins, significantly strengthening our A-arms in the process. By eliminating the smaller 2-56 hinge pin retaining screws, we’ve also eliminated the problem of the hinge pins falling out due to varying screw head diameters.
