Optimize TRF420 driveline with Tamiya SP-1643 differential pulley and case

For RC builders focused on precise handling and reliability, the Tamiya SP-1643 - TRF420 Differential Pulley & Case (37T) is a straightforward replacement to keep your drivetrain running smoothly. Made for the TRF420 racing platform, this set replaces worn components to restore consistent gear engagement and reduce drivetrain fuss during race days.

Main Benefits

Compatibility: Specifically designed for TRF420 and TA07 chassis models, ensuring seamless integration and reliable fit.
Design Efficiency: The updated layout trims weight by 1.5g to sharpen handling without sacrificing durability.
Improved Sealing: Better sealing cuts down on oil leakage compared to older versions, keeping diff oil where it belongs.
Complete Set: Includes one 37T differential pulley, one differential case, and shims of 0.2mm and 0.3mm for correct setup.

Can I use this pulley and case on a TA07 without modifications?

Yes. The SP-1643 set is made to fit both TRF420 and TA07 chassis designs, so it should install without chassis modifications when using the correct shims supplied.

How does the 1.5g weight saving affect handling?

Reducing rotating mass helps the car respond quicker to steering inputs and throttle changes. The 1.5g saving is subtle but noticeable on finely tuned TRF420 setups.

What maintenance should I do after fitting the new parts?

After installation check diff preload and shim spacing, top up diff oil as needed, and inspect seals after a few runs to confirm reduced leakage and correct seating.
