Black rear A-arms for the Associated MT8, built to outlast stock. RPM boosted the material around the inner hinge pins by 7% and widened that thicker section by nearly 40%. At the outer hinge pins, material climbs 28% and the width grows another 9%. Stock arms are roughly 1/2 in (12.7mm) thick and taper at both ends, losing nearly 30% of their thickness at the outer hinge pins. RPM arms hold the full 1/2 in (12.7mm) across almost their whole length. They taper only slightly at the inner hinge pins, down to .45 in (11.43mm) at the narrowest, to fit the largest inner hinge pin bosses allowed. Four support beams replace the usual two, making these the toughest alternative to stock. Molded from an engineering grade nylon blend.
