Race-Grade 3RACING 48 Pitch Spur Gear 93T

The 3RACING 48 Pitch Spur Gear 93T 3RAC-SG4893 is specified for competitive-minded setups that require accurate 48 pitch engagement. Its tooth profile supports uniform load distribution and repeatable power transfer in 1/10 scale drivetrains.

Technical Compatibility

Designed to integrate with standard 48 pitch pinions and housings, this 93T spur is compatible with most 1/10 racing platforms. Confirm pinion tooth count and shaft interface for optimal fit and gear ratio selection.

Tuning and Installation Recommendations

Establish correct backlash using shims or adjustment screws as required by your chassis. Inspect tooth contact pattern under light marking compound, ensure even contact, and secure fasteners to spec to avoid movement under load.

How do I verify the contact pattern?

Apply a thin tracer film to teeth, run the drivetrain slowly, and inspect the transfer area for even coverage across the tooth face to confirm correct mesh.

What clearance should I aim for at high RPM?

Maintain minimal but sufficient backlash to prevent binding; precise clearance depends on motor torque and temperature but err on the side of slightly more mesh than tight contact.

Which pinion materials pair best with this spur?

Hardened steel pinions offer longevity for high load racing, while brass pinions can be used for lighter duty or to sacrificially protect the spur under extreme impacts.
