Version Notes:#1
V5 & EXB models: Stock replacement A-arms for ARRMA #330655 and ARRMA #330656.
V4 and earlier models: Requires 1 – ARRMA #ARA713032 Shock Mount Pin & 1 – ARRMA #ARA330645 End Cap. Replaces stock ARRMA #AR330218 & #AR330219.
Tech Notes: RPM81722 & RPM81729 Replace ARRMA #ARA330654. ARRMA Kraton, Talion, Notorious, Fireteam & Outcast
Version Notes:
V5 & EXB models: Stock replacement A-arms for ARRMA #ARA330654. Inner shock mount and inner sway bar holes are stock geometry. Do not use outer shock mount and outer sway bar holes for V5 / EXB models.
V4 and earlier models: Stock replacement A-arms for ARRMA #AR330249. Outer shock mount and outer sway bar holes are stock geometry. Do not use inner shock mount and inner sway bar holes for V4 or older models unless converting to V5 / EXB suspension components.
RPM 6S Front A-arms fit V5 / EXB editions of the ARRMA Kraton, Notorious, Talion, Fireteam & Outcast. The design modifications we incorporated accommodate changes made by ARRMA for V5 and EXB versions of these vehicles. However, they are reverse compatible for older models (see “Version Notes” below).
Beefier: Our A-arms are significantly beefier than our original 6S version A-arms. Lower A-arm support beams are 30% thicker while upper A-arms are more than 22% thicker. The added thickness not only improves durability and strength, it also reduces flex. Less flex equates to more predictable suspension performance and handling.
Extra Suspension Options: The lower A-arm has an added shock mount hole further outboard. This additional position provides a lower profile suspension set-up. The shocks lay down a little further, dropping the ride height for a lower center of gravity. A lower center of gravity equates to higher corner speeds.
Caster Clip Elimination: As for the upper A-arm, we eliminated the caster spacers. This gave us room to widen the arm at the inner hinge pin mount. The extra width creates more of an “A” shape, stabilizing the upper A-arm. A more stable A-arm improves steering and suspension performance while adding strength and durability.
All RPM A-arms are molded from our nearly indestructible blend of engineering grade nylons. Tough materials equate to performance you can rely on when the conditions are at their worst!
