RPM Durango DESC410R Front Arm Set (Black)

With your purchase, receive at no cost:

This is an optional RPM Front Arm Set, and is intended for use with the  Durango DESC410R. RPM engineers have decided to tackle the notoriously fragile DESC410R A-arms, redesigning them to eliminate the weakest link in the truck. The hinge pin areas have been beefed up and in some areas are over 50% larger than stock to support the relatively small 3mm hinge pins. RPM has also eliminated as much as .004 (.1mm) of slop from some of the hinge pin areas. Thicker support beams using trapezoidal shapes provide strength, while RPM's proven blend of top secret materials provides the durability needed for these incredibly fast trucks.

RPM front A-arms swap the stock front suspension arm bushings from the outside of the A-arm to the inside. The reason is simple the screws holding the front C-hub on stock A-arms press the bushings into the C-Hub, causing a bind over time. The RPM design flips the bushings around to the opposite side so the flanged side of the bushing rests between the C-Hub and A-arm (placing metal between two pieces of plastic) accomplishing two goals; It smooths out suspension movement and prevents the bushing from gouging into the C-Hub.

RPM DESC410R A-arms also weigh less than the 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!

I was unimpressed with these RPM arms. First off, they require some "roto-tooling" to fit properly. Otherwise, the arms are too lare on both the inner and outer sides, causing the arm to not move freely at all. After getting them installed, I was happy for a while, but after I had my first decent crash, I inspected my truck only to find that the arms did not break, HOWEVER, the plastic is so soft and "stretchy," my inner hinge pin broke inside the arm, and twisted in such a fashion that it permanently deformed the hole in which the inner hing pin runs through, ruining the arm. So although the arm itself did not break, it still allowed the hinge pin to break inside of it, and with the plastic deforming the way it did, the arm is useless anyway, and cannot be re-used (as the inner hinge pin will have no support in the are in which it deformed, and will easily break again). So, I did not break one of these arms, but the first moderate crash, that wasnt a simple corner roll-over, resulted in an internal hinge pin breaking, and the arms being unuseable. Stick with the regular durango arms.... OR Durango could fix this ENTIRE PROBLEM by using beefier inner hinge pins, and more plasic around the inner arms!!!!! I don't know how they didnt see this MAJOR problem, and fix it on one of their latest versions of the DESC410... Just my two cents...
