RPM ECX Torment, Ruckus & Circuit Rear A-Arm (Black) (2)

This is an optional pack of RPM EXC Torment, Ruckus & Circuit Rear A-Arms. 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 the front A-arms, RPM rear A-arms look better than stock and are more 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, helping to reduce dirt buildup. Huge bosses around the hinge pins were added as well, reducing the possibility that a big hit will stretch the hinge pin holes. The tiny outer hinge pin locking screw has been changed 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.
