The ECX Torment, Ruckus, and Circuit RC’s continue to increase in popularity and are now receiving some love from RPM Products with a set of black front A-Arms. The RPM front a-arms for the ECX not only more aesthetically pleasing than stock. 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.
RPM also 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 screw. This helps improve overall A-arm strength while keeping the outer hinge pin locked solidly in place.
