RPM Front Arm & Bulkhead Set For Associated B4 RC10B4 #73732
This is an optional RPM Associated B4 Front Arm & Bulkhead Set. These RPM A-arms were designed to solve several customer-related complaints about the stock A-arms. Foremost is durability. RPM B4 front A-arms are designed to withstand some serious abuse! RPM has 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 by nearly 3/16” without altering suspension geometry.
RPM has 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 creates structural weaknesses. RPM moved the hinge pin retaining screws in-line with the hinge pins, significantly strengthening these A-arms in the process. By eliminating the smaller 2-56 hinge pin retaining screws, RPM has also eliminated the problem of the hinge pins falling out due to varying screw head diameters.
The RPM final focus was on slop elimination. Their strict quality control allows them to tighten up all of the tolerances without fear of binding the suspension system. The final result: a smooth, free moving suspension system with minimal slop. These tighter tolerances on the 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 B4.
RPM B4 A-arms come with all necessary mounting hardware and instructions.
Notes: These RPM B4 Front A-arms require the use of the bulkhead supply in this kit. Stock or any other aftermarket bulkheads will not work with RPM A-arms!
