Which is harder to work on?

Good thing they last twice as long... :rofl: Oh wait....sometimes they don't. My ZF6 tossed out the springs in the clutch, then the slave cyl failed, and then the clutch fork bent and failed..... and then and finally then the whole trans failed at ~70k. It lost the pocket bearing. I just exchanged it with the HO version thats in the 02-03's($1900). So far so good. I still perfer it for towing vs, 4R100's or the 5R110's. With the US gear OD behind it, it make for a awesome towing machine, Always in the right gear...

If it had a high HP truck with injectors, big oil and turbos, I'd run a 4R100 too, just for the fun factor. :cheesy smile:

What is the US gear with OD? and would I want one?

Its a gear splitter, gives you like an in-between gear (1st, 1st-over, 2nd, 2nd-over...) Mounts between the transmission and differential. It helps the rpms from falling so much when pulling. I'm not sure if US Gear makes them anymore....I know Gear Vendor does...you can pick one up for $3k IIRC. If you do a lot of heavy towing it would be handy to have. I don't know what kind of power output they are rated too though. I think I've seen some 500hp trucks with Gear Vendors unit in Diesel Power.

My rebuild with some upgrades was $2100.

Also, sometimes it's an under/over drive...it will never give you 1:1 ratio. I think for a dedicated hauler it would be a good option.

US Gear got bought out & no longer makes or services the O/U units, I just found this out last week from Barney. He has one & loves it. From what I seen when I was looking into it a few years ago I didn't think the Gear Vender was even close to the US Gear in strength, but then again I don't know everything...lol

Cool, thanks :)

I heard the same thing last week from a guy over at TDS
