Yokomo SG-4878S Spur Gear 78T 48P - for D-MAX Slipper  [SG-4878S]

Standard 48P 78-Tooth Spur Details

The SG-4878S is a 78T standard spur gear specified for use with D-MAX series dual clutch (slipper) systems on 1/10 scale models. It provides a direct fitment option where a 48P spur is required, enabling controlled adjustment of slipper engagement and overall driveline response.

For fitting, verify that the pinion matches 48P, set an appropriate gear mesh to prevent premature wear, and adjust the slipper plate and clutch engagement to match the vehicle's expected loads. Clean the surrounding area and inspect bearings and mating surfaces to ensure smooth operation before securing components.

In performance tuning, a 78T spur will alter the effective ratio compared with different tooth counts, affecting low-end punch and top speed depending on slipper settings and motor configuration. Use conservative changes and track testing to find a reliable balance between responsiveness and component durability.

Compatibility

Compatible with D-MAX series dual clutch (slipper) assemblies that use 48P spur gear specifications.
