RPM Rear A-Arms, Black (Torment/ Ruckus/ Circuit 2wd)

With the successful release of RPM front A-arms for the ECX Torment 2wd, Ruckus 2wd & Circuit 2wd. 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. They’re also lighter than stock by 4 grams each (or 8 grams in total for both rear A-arms). That means they’re 21% lighter than stock rear A-arms!

Similar to our front A-arms, our rear A-arms look better than stock, and functional in their design. 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. We added huge bosses around the hinge pins as well, reducing the possibility that a big hit will stretch the hinge pin holes. We removed the tiny outer hinge pin locking screw as well, in favor of an in-line retaining screw. This helps improve overall A-arm strength while keeping the outer hinge pin locked solidly in place.

All RPM A-arms are backed by our limited lifetime warranty against breakage and molded from some of the best materials available. If you’re looking for performance, durability and piece of mind, look no further than RPM!
