MBX5T Questions
Hi,
I am so excited that my MBX5T Prospect is in the mail and on its way to me. But I have a few questions for the MBX5T.
1) Which diff juice (oil) do you guys use? I was told that people use something like 5K front, 10K mid, and 3K rear. And that those oils are not provided in the kit.
2) As I am new to Truggies and do have experience with buggies, is there anything special that I need to pay attention to on the truggy vs. that is different on the buggy.
Thanks!!!

Do not use the little o rings that go behind the 4 small gears in the diff. I believe they are called S3 o-rings in the manual. When my truck was new I used 5,7,3 in the diffs. I am up to 5,10,5 now and will probably go up to 7 in front soon. One thing you will want is a set of 1.5mm pistons (should be black). Stock pistons are 1.4mm (should be white). The truck handles small bumps a lot better with the bigger pistons.

Also, what do you guys think of these two setup?

The little orings are there to act like thicker diff oil. Unfortunately they are inconsistent and will make the truck harder to drive. Make sure you still use the S5 orings that seal between the diff case and the outdrives or your oil will not stay in the diff.

For diff oil I use 7/10/3 and she runs like a dream.
Shocks I have 400 in the front and 350 in the rear. It only comes with one of these cant remember which one.
As far as the piston holes. I had a 1.5mm drill bit that I used to make the 1.4mm holes bigger. Or you can spend $13 and buy the 1.5's. Trust me that 0.1 makes a huge difference.

I place an order for 7/10/3 oil and 1.5mm pistons. I may have some Mugen 350 shock oil at home. I have to check. It's good I doing all this research now before I start putting my truck together, which hopefully will be this weekend.
I see both the S3 and S5 o-rings in the manual. Is this a common thing to not use the S3 O-rings?
Any other tips would be appreciated also.

Sand the diff cups flat and use double gaskets so they wont leak. Yes nobody uses the s-3 o rings in the diffs.

do NOT I repeat DO NOT double gasket them. This can throw off the mesh some guys do that but 2 gaskets will not fix the problem just build them right and you will have no problems. Also be sure to shim the diff correctly.
