Setup focused spur gear for 64 pitch applications

For competitive tuning, the 3Racing 64 Pitch Spur Gear 74T provides a 74-tooth option that yields narrow ratio increments when changing pinions. This helps crews and solo tuners converge on optimal final drive settings with predictable lap time effects. Pay attention to accurate mesh and consistent backlash to keep repeatable performance between runs.

Use shims or an adjustable gear mount to set an even tooth contact pattern. Record shim thickness or mount position to reproduce mesh between sessions.
A 74T spur provides finer ratio steps versus smaller spurs, enabling more precise tradeoffs between acceleration and top speed for lap time optimisation.
Check the gear for integrity after contact, verify mesh after each gearbox removal, and keep records of pinion/spur combinations that deliver consistent lap times.
