RPM Rear A-arms for the 4S v2 ARRMA Kraton & Outcast are designed primary for strength and durability, but we’ve added a few extra features in as well.
Our Rear A-arms reduce the amount of movement of the A-arm at the hinge pins. A tighter fit provides better throttle response and more consistent camber and toe angle settings.
Our next improvement is the addition of a third shock mount hole centered between the two stock shock mounting holes. This shock position is a great mid-point between the two extreme options provided by the stock mounting holes.
Last and most importantly, durability has been addressed. Our new A-arms are massive and uniform in thickness across their entire length! All RPM A-arms are molded from our ultra tough blend of engineering grade nylons for performance you can rely on.
Optional lightweight, yet rigid Mud Guards are also available.
