Race-Oriented Spur Gear: 3RACING 48 Pitch 81T

The 3RACING 48 Pitch Spur Gear 81T 3RAC-SG4881 is crafted with racing setups in mind, delivering uniform tooth spacing and stable engagement that supports predictable lap times. Its design helps teams fine-tune gear ratios without unexpected drivetrain variances.

Precision Fit for Competitive Builds

This spur offers consistent mesh with standard 48 pitch pinions, aiding accurate gear ratio changes and repeatable drivetrain behaviour. That predictability is vital when dialing in acceleration and top speed trade-offs.

Tuning and Durability for Race Use

While optimised for setup flexibility, the 81T maintains strength for regular track sessions. Combine correct mesh, routine inspection and appropriate hardware to keep the drivetrain performing at a competitive level.

What setup checks are critical after fitting the 3RAC-SG4881?

Verify centre distance, confirm pinion alignment, and use a gear marking compound to check contact pattern. Repeat checks after a few laps to ensure stability.

Which pinion adjustments produce better acceleration?

Smaller pinion tooth counts increase torque and acceleration at the expense of top speed. Balance pinion size with motor timing and track layout for best results.

How should teams inspect spur wear between rounds?

Perform a quick visual check for tooth rounding or chips, confirm mesh has not shifted, and replace the spur if any asymmetric wear is present to avoid unpredictable handling.
