RPM have announced the release of new lower A-arms for the Traxxas Rally ST and Telluride kits. The ideal was to create a more durable option for the standard arms and what RPM came up with is a blending of design between their extremely popular Slash 4×4 A-arms and an all-new design specifically for the Rally ST and Telluride. As for improvements, RPM eliminated the slop in the suspension system, tightened the tolerances around the hinge pins, reduced the fore and aft movement of the A-arm at both the inner hinge pin and at the axle carriers and improved the durability dramatically. As a bonus, our A-arms are lighter than stock as well. They are also more aesthetically appealing as they carry over RPM’s traditional A-arm design with their 30 degrees leading and trailing edges and huge bosses for the shock and sway bar mounts. The A-arms are moulded in RPM’s blend of durable nylons and are designed, manufactured and produced in the USA.
