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

Durable 56T titanium spur for RC18T use

This single-piece 56T titanium main spur is manufactured for fitment on Associated RC 18T trucks and serves as a direct aftermarket replacement or upgrade to worn plastic large spur gears, providing a harder tooth surface for extended wear resistance.

When fitting, verify gear mesh and inspect bearings for side play before final assembly to reduce the risk of premature wear. The main spur operates as the primary large gear in the transmission, so secure mounting, correct mesh, and clean mating surfaces are key to preserving drivetrain efficiency. Reuse the chassis mounting hardware and follow routine service checks on bearings and shafts.

For tuning, installing a stiffer titanium spur can alter drivetrain feel and longevity; re-evaluate pinion-to-spur mesh and slipper or clutch settings after installation and run a short break-in to monitor motor and ESC temperature under typical loads.
