Slipper Nut & Spring Upgrade for D-Max SD-670SP by Yokomo  [SD-670SP]

Slipper upgrade for D-Max models

This RC slipper adjustable kit is made for the D-Max series to let you tweak engagement without fitting a different clutch assembly. The design focuses on compact adjustment parts so you can refine traction response and wheel slip for your chassis.

The SD-670SP combines an adjustable nut with a dedicated spring to modify torque transfer under load. That pairing helps you set the slipper to match different track conditions and driving techniques, and it integrates directly into the D-Max style slipper system.

Fitting is aimed at experienced hobbyists: the components either replace or supplement the existing slipper hardware and let you alter engagement by turning the nut to change spring preload. Basic hex drivers cover the usual installation tasks; always check your chassis manual for final settings and torque recommendations.
