Spiral-cut front diff for Slash 4X4

The SLA1337FS spiral-cut front differential gear set from GPM is offered as an RC replacement for TRAXXAS vehicles that use the #5379X/#5379R front diff gear set. The pair is produced from 20Cr carbon steel with a hardened black finish and is designed to run inside the front gearbox to transfer motor output through the drivetrain.

The set contains a matched 37-tooth ring and 13-tooth pinion with helical spiral teeth cut for the correct spiral direction. Helical engagement smooths tooth contact and spreads load across several teeth, improving running consistency when setting gear mesh or repairing the gearbox.

Confirm your chassis service manual cites TRAXXAS part #5379X or #5379R before ordering. Installation requires disassembly of the front gearbox and standard mesh adjustment; keep shims and bearings in their original positions per the guide.

This matched ring and pinion set from GPM is supplied for front gearbox installation on compatible TRAXXAS models; confirm the chassis part number and follow the factory service manual for correct assembly and gear mesh.

Is this a direct replacement for the stock front diff?

It is intended as a replacement where the original front diff uses TRAXXAS part #5379X or #5379R. Always check your chassis manual to confirm fitment.

What are the tooth counts and why do they matter?

This set uses a 37-tooth ring and 13-tooth pinion. Matching tooth counts and spiral direction are essential for correct mesh, rotation direction and smooth operation.

Will this suit heavy off-road use?

The 20Cr carbon steel and hardened finish provide good wear resistance, but overall suitability depends on your power system and driving style; check mesh and inspect wear periodically.

Are any other parts required to fit?

Only the ring and pinion are supplied. You may need existing diff internals, bearings and shims from the original assembly to complete installation.

How do spiral gears affect gear mesh setup?

Spiral gears require the same basic mesh checks as straight-cut gears but can benefit from slightly different backlash settings due to the helix and contact patch; follow the chassis guide and make small adjustments while testing.
