This is a optional RPM Front Arm Kit, and is 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 the #70542 Rear A-arms for the ultimate in A-arm durability!
