RPM ARRMA Kraton/Outcast 6S Front Left Upper & Lower Suspension Arms are an optional upgrade for ARRMA Kraton, Notorious, Talion, Fireteam & Outcast models. The design modifications incorporated accommodate changes made by ARRMA for V5 and EXB versions of these vehicles. However, they are reverse compatible for older models (see NOTE below). All RPM A-arms are molded from RPM's nearly indestructible blend of engineering grade nylons, for performance you can rely on when conditions get rough!

Beefier
RPM A-arms are significantly beefier than the 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, RPM eliminated the caster spacers. This allowed 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.
