RPM's front right A-arms for the Traxxas Revo (reference RPM #80212 & #80215) are already compatible with the Summit but due to the extended T-Lock differential on the left side, RPM's Revo front left A-arms would not fit. That is no longer an issue with these A-arms. With a revamped cross-brace to clear the T-Lock differential, RPM's Summit front left A-arms will allow full suspension travel and significantly improve overall suspension durability.
RPM front A-arms for the Traxxas Summit are molded from their indestructible blend of engineering grade nylons for unmatched performance and durability.
