RPM Rear Suspension A-Arms for Durango DESC410R

These are the RPM Rear Suspension A-Arms for the Durango DESC410R short course trucks.

RPM engineers reviewed common breakage areas of stock DESC410R A-arms and redesigned our version to eliminate those issues. Hinge pin areas have been massively beefed up to support the relatively small 3mm hinge pins. In certain hinge pin areas, RPM A-arms are over 50% larger than stock A-arms! We’ve also eliminated as much as .004” (.1mm) of slop from some of the hinge pin areas. Stronger, thicker support beams using trapezoidal shapes provide the muscle while our proven blend of top secret materials provides the durability these incredibly fast trucks need.

RPM DESC410R A-arms actually weigh less than stock “v1” A-arms by 1.5 grams each, for a total weight loss of 6 grams or almost a quarter ounce (when using both front and rear A-arms). That number becomes even larger when compared to DESC410R “v2” A-arms.

Whether racing, bashing, or anything in-between, RPM A-arms are your DESC410R solution!
