Description

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.

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 pairs with one left and one right A-arm in each package.

Tech Notes: RPM SC8 / RC8 a-arms may fit later versions (SC8.2 / RC8.2) but are not a direct replacement. Sway bar mounts and shock locations are geometrically different.
