Rear A-Arm: ARRMA Kraton, Outcast 4S BLX

RPM A-arms for 4S BLX versions of the ARRMA Kraton & Outcast are designed primarily for strength and durability but a few extra features have been added in as well.


Slop Elimination. RPM A-arms reduce the amount of movement of the A-arm at the hinge pins, providing better steering response and more consistent camber, caster and toe angle settings.

The addition of a second shock mount hole further out on the arm provides a lower profile suspension set-up. This shock position allows the suspension to lay down a little further, dropping the ride height for a lower center of gravity and better cornering stability.

RPM's new A-arms are massive! At almost 25% thicker than stock, the A-arms will take a pounding and come back for more! All RPM A-arms are molded from a nearly indestructible blend of engineering grade nylons for performance you can rely on when conditions are at their worst!
