OVERDOSE OD3839 Belt Drive Ball Differential Kit for GALM

OVERDOSE OD3839 Belt Drive Ball Differential Kit for GALM Rear Mount Kit Type-2

Upgrade your OVERDOSE GALM drivetrain with the OVERDOSE OD3839 Belt Drive Ball Differential Kit, designed for the Rear Mount Kit Type-2 system.

This premium belt-drive differential setup provides smooth power delivery and improved drivetrain response while giving drivers the tuning advantages of an adjustable ball differential. OVERDOSE increased the belt width to 5mm for improved durability and developed a dedicated 39T ball differential pulley and 15T center pulley for the system.

The differential uses smaller 2.4mm diff balls to reduce rotating mass while delivering smooth, consistent operation with excellent resistance to slipping. A dedicated belt tensioner also allows precise adjustment of belt tension for proper drivetrain performance.
