One of the most demanded RPM A-Arms recently is for the ecx Torment 2WD, Ruckus 2WD and circuit 2WD. You wanted them; we made them! these new arms are everything you've come to expect from the leader in molded aftermarket 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. Our A-arm design looks more aesthetically pleasing than stock, yet the design is more than just good looks. The angled leading and trailing edges are more aerodynamic and allow the A-Arms to transition up and over objects much more easily 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 screw. This helps improve overall A-arm strength while keeping the outer hinge pin locked solidly in place. You can't go wrong with RPM!
