Valvoline is what AGR recomends and warranties. I didn't want to cross that line. That is what they use for testing and manufacturing. I just went with it, but another synthetic should work. Make sure it is not red, they will not warranty it. The factory pump puts out just under 1.5 GPM @1500 psi on a good day. The AGR more than doubles that everday.
I got the pump directly from AGR at $129 (This included core charge) plus $20 shipping.
I got the box from 4 Wheel Parts for $272 including shipping. No core was needed. AGR Recommended I buy from them, said it was cheaper and it was.
Magnafine Filter $32.15 including shipping. Bought directly from company. http://www.emergingent.com/subpage1Magnefine.htm
6 Row Cooler $29 from Summit Racing. There is a small shipping/handling Charge.
Local parts store sells the fluid for $3.29 a quart. If you don't replace everything, you have to flush out the old and that gets expensive.
Don't forget to ad a little extra for hose clamps and return line. I needed more than what was supplied.
This setup works wonders for the MileMarker hydraulic winch, according to MileMarker. I called and verified because I planned for the 10,500lb.2 speed setup they have.
The part number on the Summit cooler wasn't readily avaliable to me. If you want it, let me know and I'll dig it up at home.
If it ain't broke, I can probably still fix it.
