Serpent 601281 Lightweight Differential Outdrive Upgrade  [SER601281]

Race-ready outdrives for precise 1/8th GT handling

Serpent 601281 lightweight differential outdrives are made for drivers who prioritise consistency and control on the track. Built for 1/8th on-road GT cars, this set reduces internal drag and helps maintain steady lap times while extending differential life.

Precision engineering with a centring cross pin

The slimmed down outdrives and the integrated centring cross pin work together to create a firmer axle feel without locking the diff. That balance cuts down on unwanted binding in the gears and keeps the drivetrain operating smoothly under race conditions.

Practical benefits for club and national racers

• Enhanced Durability: Components are designed to resist wear so you get more running hours between rebuilds.
• Smoother Operation: Less gear friction delivers cleaner power transfer and easier throttle control.
• Improved Lap Consistency: Lower differential drag helps drivers hit more consistent lap times.
