I found these on Quad 4x4, has anyone tryed them?

 

i built my own last year and it works great for my gear oil i piped it into the front an rear end as well, just bought a nv4500 filter, taped both pto covers. one for in one for out. ran air brake line to a pump then to the front diff cover and one to the rear diff cover. i run valvaline 75w-140 full synthetic in mine

 

so then are you running 75-140 in the 4500 too? Seems like that would be too thick for that trans.

 

and your synchros are gonna go out...only approved fluid in the 4500
