Spiral front differential for Slash 4X4

The SLA1337FS spiral-cut front differential gear set from GPM is an RC replacement for TRAXXAS platforms that use the #5379X/#5379R front diff gear. The pair is manufactured from 20Cr carbon steel and finished hard and black for use inside the front gearbox, where the ring and pinion pass drive from the motor into the drivetrain.

This supplied gear pair is a matched 37-tooth ring and 13-tooth pinion cut with helical spiral teeth. The spiral geometry gives smoother engagement and spreads load across multiple teeth, helping maintain predictable drivetrain feel during setup and repairs.

Before fitting, verify your chassis manual lists TRAXXAS part #5379X or #5379R as the original front diff gear set. Installation requires access to the front gearbox and basic gear mesh adjustment; keep shims and bearings in the correct positions per your service guide.

This GPM front diff gear set is supplied as a matched ring and pinion intended for front gearbox installation on compatible TRAXXAS models; verify your chassis part number and follow your service manual for correct assembly and gear mesh.

Can I fit this into a Slash 4X4 front gearbox?

Yes. This matched 37/13 set is made to replace the factory front diff where the chassis uses TRAXXAS #5379X or #5379R; confirm your manual before fitting.

Is the material suitable for high power setups?

The gears are 20Cr carbon steel with a hardened finish, offering improved wear resistance over softer stock gears but check your drivetrain loads and tune gear mesh accordingly.

Do I need special tools to install it?

Standard model workshop tools are sufficient; you will need access to the front gearbox, feeler shims for mesh, and basic bearing handling skills.

What exactly comes in the box?

The packing block lists one 37-tooth spiral-cut ring gear and one 13-tooth spiral-cut pinion gear only; no bearings or diff internals are included.

How should I check compatibility before purchase?

Compare your chassis part number with the Compatible Models list and verify the factory front diff part number in your TRAXXAS service manual before buying.
