RPM A-arms for the ARRMA V1 to V4 Kraton, Talion, Notorious & Outcast as well as the Durango DEX8T are designed primary for strength and durability but we’ve added a few extra features in as well. First is slop elimination. Our A-arms reduce the amount of movement of the A-arm at the inner mounts, providing for better steering response and more consistent camber, caster and toe angle settings. Our next improvement is the addition of a second shock mount hole further out on the arm, providing for a lower profile suspension set-up, allowing the shocks to lay down a little further, dropping the ride height for a lower center of gravity. As an added bonus, our front and rear A-arms are roughly 10% lighter than stock (front 59.5g – RPM versus 66g stock) (rear 48g - RPM each versus 53g for tock)!

RPM A-arms are designed with leading and trailing 30° chamfered edges for smoother transitions over obstacles too tall for the suspension to clear. As an added benefit, these chamfered edges are more aerodynamic than stock as well. All RPM A-arms are molded from our nearly indestructible blend of engineering grade nylons for performance you can rely on when the conditions are at their worst!
