RPM GT2 A-arms were designed to solve several customer-related complaints about the stock A-arms. Foremost is durability. The GT2 front and rear A-arms are designed to wit'stand some serious abuse! RPM's 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!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. 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. RPM GT2 A-arms come with all necessary mounting hardware and instructions. RPM GT2 A-arms are sold in pairs while our front A-arms are sold in pairs as well and include a new front bulkhead in the package.
RPM Front A-arms can be used on the Associated T4. 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 will no longer be needed. RPM Front A-arms.
