RPM SC10 2wd / T4 A-arms were designed to solve critical durability issues stemming from stock rear A-arms. Our SC10 2wd / 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 c!" 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 stockers. 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. Our final focus was on slop elimination. Our strict quality control allows us to tighten up all of our tolerances without fear of binding the suspension system. The final result is a smooth, free moving suspension system with minimal slop. Our tighter tolerances on our A-arms allows other critical adjustments such as camber and toe angles to be much more consistent, providing better and more consistent control of the SC10 or T4. RPM SC10 2wd / T4 A-arms come with all necessary ing hardware and instructions. RPM SC10 / T4 A-arms are sold in pairs and are backed by our industry-leading breakage warranty. Combine a set of RPM rear A-arms with a set of RPM front arms (#70762 or #70765) and if you c, you'll still finish your race, not your day!.
