GPM Associated RC 18T 56T Titanium Main Spur TAR056T Set  [TAR056T]

Precision titanium 56T main gear for RC18T platforms

This single-piece 56T titanium main spur is CNC produced for aftermarket fitment on Associated RC 18T transmissions, intended as a durable replacement to standard plastic gears. The design focuses on a hardened tooth surface to reduce wear rates under typical 1/18 class loads while maintaining correct tooth geometry for reliable meshing.

Installation requires verification of gear mesh and bearing clearance to avoid point loading and premature wear. As the primary large spur in the drivetrain, ensure secure mounting and clean mating surfaces to preserve power transfer efficiency. Use original mounting hardware where applicable and include the gear in routine drivetrain inspections.

From a performance perspective, swapping to a stiffer titanium spur can influence perceived drivetrain stiffness and component longevity; after fitting, re-evaluate pinion engagement, slipper or clutch settings, and perform a controlled run-in while monitoring motor and ESC temperatures.
