eaton gears, rehashed
 

howdy all, I recently stumbled upon an interesting bit of information. According to an individual on pirate4x4, the 1963 chevrolet light truck TSM states that there is a 5.83 gear ratio available for the Eaton H072 axle. Can anyone confirm or deny this?

I have no documentation, but I wouldn't be suprised.

ihave been told there were 6.14 also pull the house gears

Holy cow! I thought 5.13 (or something thereabouts) was the lowest you could get! I could not imagine driving something with gears that low. My 4.56 gears already feel pretty dang low as it is.

Why the he!! would anyone want that low of a gear, I always thought 4:11's or even 4:57's were low enough. :confused:

If I could find a set of 5.83's, I would be all over them like s**t on toilet paper.
But I will probably just stick with my 5.14's.

I don't know if these fit in the HO72 units, but this page lists Eaton diffs in 6.14, 6.50... 7.17 and... 7.60 sizes!! HOLY CRAP!! :eek: :eek: :eek:

DAM!!!!!!! With 7.60's, 35" tires, and a tranny going 1:1, the engine would be turning about 5000RPM's at 70MPH. :eek:

thanks for the help but that is for larger Eaton axles used under bigger trucks.

I do know that you can get as low as 7.17 gears for Dana 60 and 70 axles. pretty crazy stuff.

anyone?

Remember the real deep gears were normally paired with real tall tires. The 20 inch split rim tall by skinney deals, so that cur the revs down considerally.

Yeah Longhorn Man you gotta point there. The tires are around 36 to 40 inches tall for the c/40 and up trucks.

cough...cough...39.5 x 17 TSLs....;)
