Whether you’re out having fun bashing or in the middle of the A-main at a national event, nothing is more frustrating than breaking an A-arm. That’s where RPM steps in. RPM A-arms for the Associated SC8 & RC8B are designed to prevent that from ever happening again. These A-arms are tough as nails and designed to take some serious punishment! Every aspect of the design on these arms is there to either improve strength or durability. Additionally, we’ve cleared the A-arms in areas known to rub on the stock A-arms, allowing extra droop for more suspension travel over rough terrain or big jumps.
Exclusive features of RPM A-arms include: Molded-in shock mounts which means no more lost screws or extra weight from those screws on the arms (each RPM Rear A-arm is actually 3 grams lighter than stock, saving 6 grams of unsprung weight!). Elimination of the stock lower shock mount pin in favor of a new 5-40 screw, which eliminates .004” of slop in the pivot and improves suspension accuracy. Leading and trailing 30-degree edges help the vehicle to more easily transition up and over objects too tall for the suspension to clear and improve suspension aerodynamics.
