RPM Products ECX Torment 2wd Ruckus 2wd & Circuit 2wd Rear A-arms

These rear A-arms are 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 RPM's front A-arms, these 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. They added huge bosses around the hinge pins as well, reducing the possibility that a big hit will stretch the hinge pin holes. RPM 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.
