This helps improve overall A-arm strength while keeping the outer hinge pin locked solidly in place.Īll RPM A-arms are backed by our limited lifetime warranty against breakage and molded from some of the best materials available. We removed the tiny outer hinge pin locking screw as well, in favor of an in-line retaining screw. We added huge bosses around the hinge pins as well, reducing the possibility that a big hit will stretch the hinge pin holes. The angled leading and trailing edges are more aerodynamic and allow the A-arms to transition up and over objects much more easily and helps reduce dirt build-up than the blunt, flat-edged design of stock A-arms. Similar to our front A-arms, our rear A-arms look better than stock, and functional in their design.

That means they’re 21% lighter than stock rear A-arms! They’re also lighter than stock by 4 grams each (or 8 grams in total for both rear A-arms). we now have rear A-arms available as well! They’re stronger than stock, beefier to help survivability during those unexpected incidents and built to tighter tolerances, making critical suspension settings much easier to lock down. With the successful release of RPM front A-arms for the ECX Torment 2wd, Ruckus 2wd & Circuit 2wd. Fits 2wd versions of the Torment, Ruckus & Circuit only – replaces stock ECX #ECX1019
