RPM Front 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. First is slop elimination. These Front A-arms reduce the amount of movement of the A-arm at the hinge pins, providing for better steering response and more consistent camber, caster and toe angle settings. RPM's next improvement is the addition of a second shock mount hole further out on the arm, providing for 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. Their A-arms are massive and uniform in thickness across their entire length! All RPM A-arms are molded from an ultra tough blend of engineering grade nylons for performance you can rely on when conditions are at their worst!
