Important Notes

Grease / Maintenance

This differential set comes fully assembled, but the external grease is not pre-applied. Internal gears are pre-filled with grease, but for optimal performance:

• Open and top off or replace with your preferred differential oil

• Ensures smooth operation and long-term durability

Aluminum Housing Fit

• Manufactured to precise tolerances for a snug, exact fit

• When reassembling, press both halves firmly together until a distinct click confirms closure

Break-In Period (Highly Recommended)

• Run your vehicle at half power or on 2S batteries for 1–2 full cycles before stepping up to 3S

• Proper break-in ensures the internal components seat correctly and maximizes longevity

Shimming

• Proper shimming may be required for correct operation depending on your setup

• Incorrect shimming can cause excessive wear or output gear failure

• Always check fitment and adjust as needed before running
