RPM customers have been asking for a more durable option for Rally ST & Telluride A-arms. What we came up with is a blending of design between our extremely popular Slash 4x4 A-arms and an all new design specifically for the Rally ST & Telluride.
As for improvements, we 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 (1.5g ea. or 6 grams for a full set of four).
We can't forget about how much more aesthetically appealing the RPM versions look either. RPM A-arms carry over our traditional A-arm design with our 30° leading and trailing edges and huge bosses for the shock and sway bar mounts.
RPM A-arms are molded in our blend of incredibly durable nylons and are backed by our industry leading warranty. Designed, manufactured and produced right here in the USA!
Tech Notes: RPM A-arms for the Traxxas Rally ST / Telluride are sold in sets of 1 left and 1 right A-arm in each package. Two packages will be needed to complete one vehicle. RPM A-arms replace stock Traxxas #6731.
