โ ๏ธ Please Note:ย This Slash 4×4 Complete Differential comes fully assembled but does not include external grease pre-applied. You will need to add grease according to your preference before installation. The internal differentials are pre-filled with grease, but for optimal performance and long-term durability, we recommend opening them up and either topping off the grease or replacing it with your preferred differential oil. The aluminum differential housing is manufactured to precise tolerances, ensuring a snug, exact fit. When reassembling, press the halves together firmly with both hands until you hear a distinct click, indicating it is fully closed with no gaps.
Break-In Period (Highly Recommended):
Once fully installed, it is highly recommended to perform a low-power break-in period. Run the vehicle at half power or on 2S for one to two full battery cycles before stepping up to 3S power. This helps ensure proper seating of internal components and extends the life of the differential.
Important Installation Note:
Depending on your specific setup, proper shimming may be required for correct differential operation. Failing to shim the differential correctlyโwhen neededโcan result in excessive wear and potential output gear failure. Always check fitment and adjust as necessary before running.

I ordered the complete front and rear differentials for my Rustler Ultimate and they fit perfectly. I Instantly noticed how smooth and quieter my Rustler is while driving and the spiral cut gears they have installed are amazing. I canโt wait to purchase more from this company. Definitely recommend. Hopefully shipping will continue free, thatโs a great offer. Note: If you have the stainless steel upgraded hardware like I do, double check the lengths before installing as I did. The stainless steel was a little longer so I used their hardware provided.
