Spiral differential upgrade for Slash 4X4

The SLA1337FS spiral-cut front differential gear set from GPM is made as a direct-fit aftermarket option for TRAXXAS cars that use the #5379X/#5379R front diff gear. Cut with helical teeth and produced from 20Cr carbon steel with a hardened black finish, the gears are intended to run inside the front gearbox, transferring motor power smoothly through the drive train.

The matched 37-tooth ring and 13-tooth pinion are ground for correct mesh and spiral direction. The helical tooth form reduces shock loads on single teeth by spreading force across several contact points, which helps when dialing in gear mesh and during normal running.

Confirm your vehicle manual lists TRAXXAS part #5379X or #5379R before fitting. Front gearbox access and standard mesh adjustment are required for installation; preserve shim and bearing positions per your chassis guide.

Supplied as a matched 37/13 ring and pinion, this GPM front diff gear set is intended for front gearbox installation on compatible TRAXXAS models; check your chassis part number and follow the service manual for correct mesh and assembly.

Will this replace TRAXXAS #5379X/#5379R directly?

In many cases yes; the SLA1337FS matches the 37/13 ring and pinion configuration. Always double check your manual to confirm the factory front diff part number before ordering.

How does spiral cut affect performance?

Spiral-cut helical teeth engage gradually and share load over more tooth area, producing smoother operation and reduced localised stress compared with straight-cut gears.

Any prep needed before installation?

Check bearings and shims, clean mating surfaces, and set correct gear mesh following the chassis service instructions for the front gearbox.

Is any other hardware included?

No, only the 37-tooth ring and 13-tooth pinion are included as shown in the packing block; other diff parts are not supplied.

Where can I get service instructions?

Refer to your TRAXXAS chassis service manual or the manufacturer support site for gearbox disassembly, reassembly and correct mesh setup procedures.
