87 Tooth DP48 Spur Compatible with YZ-4SF

This spur gear is supplied as a replacement item for YZ-4SF chassis variants and intended to pair with dual pad slipper systems on 1/10 scale RC cars. The part meets the DP48 specification and carries 87 teeth, matching the 48 pitch tooth standard in the listing.

Installed on the slipper hub, the gear transmits motor torque through the slipper assembly into the gearbox while allowing slip when overload occurs. When fitting, set an accurate gear mesh with the pinion and inspect dual pad surfaces and slipper preload to preserve consistent operation.

Tuning impact: selecting an 87T spur alters the driven speed and torque band relative to the motor and pinion choice; altering spur or pinion counts affects on-track acceleration and top speed, so adjust slipper settings after any gear change.

Compatibility

  • B-YZ4SF
  • B-YZ4SF2-1
  • MOR-010
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 this spur alter handling or responsiveness?

Changing to an 87T spur reduces effective gearing compared to smaller spurs, typically smoothing acceleration but lowering peak speed; pair it with an appropriate pinion to tune responsiveness to your driving style.

How does DP48 affect pinion compatibility?

DP48 indicates standard 48 pitch teeth, so use 48 pitch pinions only for correct mesh. Mixing pitches can cause poor engagement and accelerated wear.

How should I monitor slipper pad wear after changing the spur?

After replacing the spur, run a few short tests and recheck pad thickness and slipper preload; increased slippage or inconsistent engagement indicates pads or preload need adjustment.
