RPM GT2 A-arms were designed to solve several customer-related complaints about the stock A-arms. Foremost is durability. Their GT2 front A-arms are designed to withstand some serious abuse! They've redesigned the entire front end, replacing the stock front bulkhead with a version that helps spread impact forces over a larger area at the inner hinge pin mounts. RPM front A-arms are wider at the inner hinge pin mounts by nearly 3/16" without altering suspension geometry. RPM 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 at that point. They moved the hinge pin retaining screws in-line with the hinge pins, significantly strengthening the A-arms in the process. By eliminating the smaller 2-56 hinge pin retaining screws, they've also eliminated the problem of the hinge pins falling out due to varying screw head diameters, which seems to be a rather large problem. RPM's final focus was on slop elimination. Their strict quality control allows them to tighten up all of their tolerances without fear of binding the suspension system. The final result-a smooth, free moving suspension with minimal slop. RPM's tighter tolerances on their A-arms allows other critical adjustments such as camber and toe angles to be much more consistent, which provides better and more consistent control of the GT2. RPM GT2 A-arms come with all necessary mounting hardware and instructions. RPM GT2 A-arms are sold in pairs and include a new front bulkhead in the package. Tech Notes: RPM Front A-arms can be used on the Associated T4 & SC10. However, the outer front T4 hinge pins will need to be replaced with the outer front hinge pins from the GT2 (stock Associated #7927). Additionally, the upright spacers used on the T4 / SC10 will no longer be needed. RPM Front A-arms require the use of the bulkhead supplied in the kit. Stock bulkheads will not work with RPM A-arms.
