Yokomo SD-670SP Slipper Adjustable Kit for D-Max adjustable slipper clutch accessory  [SD-670SP]

Adjustable slipper kit for D-Max

This is an RC-scale slipper adjustable kit designed for the D-Max series, intended to give fine control over slipper engagement without replacing a full clutch assembly. The kit is compact and focused on the adjustment interface used to tune traction and wheel slip behaviour on model cars.

The SD-670SP provides an adjustable nut and spring combination that work together to alter how the slipper transfers torque under load; this lets you dial in slip characteristics for different track surfaces and driving styles. It is supplied as a small parts kit that integrates with the D-Max slipper system.

Installation is straightforward for experienced hobbyists: the parts replace or complement the existing slipper components and allow incremental changes to engagement by adjusting the nut preload on the spring. No special tools beyond standard hex drivers are required for basic setup, but follow your chassis manual for final assembly and torque settings.
