What do you figure your crawl ratio is?

Are you still running 4:11's

Rezarf <><

Not sure on the crawl ratio, never paid much attention to it. SM420, 3spd case, 4.11 gears, If I recall correctly that setup should be around 69 or 70 to 1.

Mike, show us your cool hydroboost setup! Explain some of this possible issues with it and how you overcame them.

Cain't find the pics

I just recently installed hydro-assist from foxfab. A major consideration for me was not wanting to drill out of steering box for hydraulic fittings since my box came from O'Reilly's with a lifetime warranty. Erik suggested I check out EMS Off-Road. They make a billet front cover that is ported for a hydraulic fitting for hydro assist. They also offer a drilled and tapped top cover and IIRC both covers ran ~$100. I ordered both so I could keep the OEM covers in case I never keep to use the warranty. The install was pretty straight forward and the only hangup for me was the extended front cover barely touched the front bumper. A couple quick cuts with the angle grinder and it's good. I do like not having the turn the front locker off and on everytime I need to steer the rig and with 38's I'm sure the gearbox will last a lot longer not having to do all the work.

If my computer weren't dinking up this morning I would at least have links for ya to foxfab (he's on Mud and Pirate) and I think the other is emsoff-road.com

7.05 * 2.313 * 4.11 = 67.02
