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, but 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.
