RPM Front A-arms & Bulkhead for the HPI Blitz
RPM front A-arm design eliminates the stock front bulkhead in favor of a new design that spreads impact forces over a much larger area. This distributes those forces more evenly and helps prevent breakage of the more sensitive, more expensive and fragile inner components. 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.
RPM next objective – eliminate the slop – was a simple matter of using closely controlled materials processing and tight mold tolerances to allow a free moving suspension system without unnecessary free play. We tightened the sizes around the hinge pins and eliminated fore and aft movement at the inner and outer hinge pins (the stock front end, for example, allows over 1/16” (1.5mm) of forward and rearward movement)! The end result is a suspension system that will hold camber, toe and caster settings nearly perfect, even under the toughest of conditions.
