Product Description

The long-running success of RPM A-arms for the original GT has led to the release of our A-arms for the newest gas truck to come from Associated – the GT2. RPM GT2 A-arms were designed to solve several customer-related complaints about the stock A-arms. Foremost is durability. Our GT2 front A-arms are designed to withstand some serious abuse! We’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 GT2 rear A-arms are just flat-out beefy!

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 at that point. 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, which seems to be a rather large problem.

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 – a smooth, free moving suspension 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, 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. 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.
