Rear A-Arms, for 4S V2 Arrma Kraton & Outcast Duster 5mm SlottedRPM Rear A arms for the 4S v2 ARRMA Kraton & Outcast are designed primary for strength and durability, but they've added a few extra features in as well. These 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. RPM's next improvement is the addition of a third shock mount hole centered between the two stock shock mounting holes.
