RPM front A-arms for the SC8 & RC8B are built with the same principles and design characteristics built into all RPM A-arms. Some of those design considerations include cleared areas known to rub on the stock A-arms. We also molded in the shock mounts, which means no more lost screws or extra weight from those screws on the arms (RPM Front Lower A-arms are slightly lighter than stock!). To help reduce slop in the suspension, we discarded the stock shock mount pin and setscrew in favor of a new 5-40 screw, which eliminates .004â€ť of slop in the pivot and improves suspension accuracy. Leading and trailing 30-degree edges on the a-arms help the vehicle transition up and over objects too tall for the suspension to clear and, as a side benefit, those angles improve suspension aerodynamics. All this comes at a weight identical to the stock arms!
RPM A-arms are molded in our trademark blend of bulletproof nylons and are factory-backed by our industry-leading breakage warranty. Molded in black and sold in sets, including one lower left A-arm, one lower right A-arm, two upper A-arms and all necessary hardware in each package.
