FRONT LEFT A-ARMS - BLACK - FOR SUMMIT, REVO & E-REVO motor The innovative outer diameter structure

The innovative outer diameter structure of the fully exposed stator core maximizes the heat dissipation area and increases the direct heat dissipation area by 25

Heavt-duty internal construction

540 class motor (30-27 turn recommended)

but 9 pinion gear settings can be used from 29T - 37T to produce a wide range of gear ratio settings

FRONT LEFT A-ARMS - BLACK - FOR SUMMIT, REVO & E-REVO motor The innovative outer diameter structureRPM'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.
