• Compatible with the 2WD ECX Ruckus, Torment and Circuit
• Improved hinge pin hole design
• Limited lifetime warranty

 The RPM A-arms feature angled leading and trailing edges which are more aerodynamic and allow the A-arms to transition up and over objects much more easily. Bosses have been added around the hinge pins as well, reducing the possibility that a big hit will stretch the hinge pin holes. The outerhinge pin locking screw has been updated with an in-line screw. This helps improve overall A-arm strength while keeping the outer hinge pin locked solidly in place.All RPM A-arms are designed from our incredibly tough blend of engineering grade nylons and are backed by our limited lifetime warranty against breakage. You can’t go wrong with RPM!
