Tamiya SP-1643 upgrade for your TRF420 drivetrain

When you need reliable drivetrain feel, the Tamiya SP-1643 - TRF420 Differential Pulley & Case (37T) provides a direct-fit solution for racers and hobbyists. Built for the TRF420 race chassis, this set swaps in fresh components to help maintain predictable diff behaviour and reduce maintenance interruptions.

Notable Details

Compatibility: Engineered for TRF420 and TA07 platforms to ensure a clean fit and consistent operation.
Design Efficiency: The refreshed design saves 1.5g of weight, helping the car turn in with less inertia.
Improved Sealing: Enhanced sealing lowers the chance of oil seepage versus older assemblies, making upkeep easier.
Complete Set: Supplied with a 37T differential pulley, differential case, and 0.2mm and 0.3mm shims for setup tuning.

Will the included shims cover most setup needs?

The 0.2mm and 0.3mm shims give you common spacing options for initial setup. For fine tuning you may still use other shim sizes depending on your diff clearance and play preferences.

Does the case improve leak resistance over older parts?

Yes. The revised sealing surfaces reduce oil leakage compared to prior designs, which helps keep diff oil inside and lowers clean up after runs.

Is this suitable for sprint and carpet circuits?

It suits both sprint and carpet layouts since it maintains smooth driveline operation and consistent diff behaviour, but final tune will depend on oil weight and shim selection.
