RPM Products Rear A-Arms for Associated B64 & B64D

RPM A-arms are the toughest A-arms on the market so a rough landing or a hit from another competitor won't take you out of the race! To increase durability, RPM uses the best possible engineering grade nylons as well as using in-line screws to retain the outer hinge pins. Elimination of that extra hole increases the durability of our B64 arms tremendously.
