    Diff cup and diff housing oil/grease type?

    Iím installing XO-1 diffs into my monster slash. Running a 2650 in it. What type of grease or oil should I put in the diff cups and the diff housing?

    For the ring and pinion I just use Marine Grease. As for the inside of the diff, you can use whatever weight oil suits your driving style. I prefer 100k in the rear and 60k in the front for bashing.

    I have always used the stock weight diff fluid inside the diff and never had problems or the desire to go thicker.

    For the Ring and Pinion i have used as mentioned above, Marine grease which will help repel water if you plan on getting it wet.

    Recently i have been running Lucas oils "Red n tacky" since i do not get my truck wet.

    I did the same XO-1 conversion on one of my Rusty 4x4s (plus I plan to convert my Slash 4x4, and my other Rusty 4x4). I used 15K & 10K...but, I'm using them for racing, not bashing.

    Consider what you're using the vehicle for in order to help determine what weight diff fluids to use. To give an example of what I mean, two of my vehicles (currently have 6) use only 5K...although, I should mention that all vehicles are for racing.

    Its all trial and error. I Used to run the stock 30,000 weight in the front and 100,000 in the front. I still run the stock weight in the front. I now run 500,000 in the rear.

    My basher rig has 10K front and 100K rear.
    My street rig has 80K front and 200K rear.

    Housings in both rigs have Peak's high-temo red grease.

    They have an I-beam to handle more power. Remove parts that are not in the XO-1 exploded view and replace with the ones that are. Pretty short list.
