High-precision spur for D-MAX dual clutch

This 81-tooth spur is built to work with D-MAX series dual clutch and slipper arrangements. The SG-4881S is a 48P, 81T precision spur designed to slot into slipper-equipped drivetrains and provide a reliable reference tooth count for fine mesh and ratio checks.

Installation notes: confirm pinion-to-spur mesh before completing assembly, set slipper preload to your chassis baseline, and verify clutch engagement after installing the gear. Use correct shim spacing and recheck bearing alignment to reduce premature wear. These are general fitting and maintenance suggestions for on-road RC drivetrains.

Tuning role: changing spur tooth counts modifies the effective final drive and helps balance acceleration against top speed on track. The 81T choice is commonly selected by drivers seeking a conservative ratio for smoother engagement with slipper-equipped D-MAX dual clutch systems.

Compatibility

Compatible with D-MAX series dual clutch systems and slipper-equipped drivetrains as indicated by the product designation.
Remark :
Due to limited stock availability, please notice that some Yokomo items may have to order from the factory and the ready time is around 4-6 weeks. Customer purchases the item is assumed to accept the waiting time which allows us to order directly from the manufacturer if the item is out of our warehouse.

Will the SG-4881S fit every D-MAX dual clutch variant?

The designation targets D-MAX series dual clutch setups, but fitment can vary by chassis revision. Check your chassis' slipper interface dimensions and confirm tooth spacing before final installation.

How do I set gear mesh after fitting this spur?

Fit the pinion and spur, establish a moderate mesh using a business card or feeler method, rotate the drivetrain to ensure smooth engagement, then secure fasteners and recheck mesh under load.

Should I change slipper preload when switching to 81T?

Yes. Swapping to an 81T spur changes final ratio and torque through the slipper; re-evaluate preload and engagement to maintain your preferred clutch behavior.
