This is a set of optional RPM Rear Arms, and are intended for use with the Associated RC10 buggy. The Associated RC10 is slowly fading into history but there are still many viable, strong, and competitive RC10’s still out there. Unfortunately, parts are becoming harder to find. RPM has stepped up and re-released these A-arms to help keep those RC10’s running strong. These RC10 A-arms are molded in black from RPM's bulletproof blend of nylons and are sold in pairs. Combine these with a set of #70442 front A-arms and you’ll never have to worry about shelving your much loved RC10 because of an A-arm break.
