Competition Focused 48 Pitch Spur from 3Racing

The 3Racing 48 Pitch Spur Gear 67T (3RAC-SG4867) is targeted at drivers refining final drive ratios for track performance. Its 67 tooth count offers a controlled compromise between acceleration and top end, while the composite body aims to reduce rotating mass and preserve predictable tooth engagement under load.

Technical Highlights for Tuners

  • Tooth Count: 67T for measured torque delivery and improved corner exit traction
  • Pitch: 48P to match industry standard pinion options used in competitive classes
  • Material: Composite chosen to balance stiffness and wear resistance for repeatable setup changes
  • Usage: Suitable for drivers tuning gear ratios for heat to heat consistency

What is the effect of a 67T spur on final drive for track setups?

A 67T spur reduces final gearing compared to smaller spurs, improving low to mid range torque which can aid corner exits and throttle modulation.

How does material choice influence gear mesh stability?

Composite spurs provide consistent tooth profiles with less mass, which helps maintain stable mesh and reduces stress on pinion bearings during transient loads.

Any setup tips when switching to this spur for competition?

After installation confirm backlash and mesh, run a few low speed laps to seat the teeth, then fine tune pinion size if you need to regain top speed or increase acceleration.
