other gear ratios for Rockwell axles?

[maddawg308]

Is there an aftermarket source for different gear ratios for the Rockwell axles? I went to Boyce Equipment's website and they only sell with standard gear ratios, I thought it anyone had different ratios they would.

Use the search. It's been covered at least 3 times. 4.90 ratio from ouverson. 1500 per axle. Don't think you are going to want them!

Ouverson Engineering makes a 4.90 to 1 ratio, mostly for the off road guys. Not sure how it would work in a deuce with the limited horsepower.

Many ratios available in the afternarket. All at a price that eliminates 90% of us cheap azz mv owners from getting them

Why do I need search, when I have you guys? You guys know a lot more than Search does!

Yeah, $1500 per axle is for the Jeep buggy crowd, they have all the cash. But it's about what I figured.

How about some type of overdive or underdrive unit, i know being all wheel drive it is harder, but it is also doable. Somebody just needs to make a 3 speed transfercase or a conversion for the transfercase.

Already done, and I have one. M35tom makes a kit to change out the 5th gear in the transmission for a higher overdrive. Lot less work than changing a transmission or adding a brownie box. Plus you get to keep your PTO's. Also cheaper than one set of 4.90's.

Has anyone entertained the idea of commercial axles? I think some of the Petes and KWs had a variety of ratios to choose from. Keeping both rear axles as drivers is still possible since those axles have an output shaft through the axle housings (for the rear rear) instead of over the top of the differential. A lot of utility company trucks even have live steer axles so they're out there too.
True they aren't the "stock" double reduction type, but if you're suddenly able to get comfortable, non-redline 60 and 70 mph freeway speeds ?!?

Personal experience with 5th over transmissions; I put one in an M-37 and found I'd just passed the h.p./torque threshhold. The truck could barely hold it's own on flat ground, without a headwind, in 5th and was in effect faster in 4th than in top gear.

That is Why Tom says to bump the power a tad and add a pyro. The engine can make the power to move it just you have to watching things on the long hills. Were not talking 300 HP here but enough.

You're right Westech. I had a 318 (bone stock) in this M-37 but still managed to hit the 'magic combination'.

I remember when we picked up my friends M37 from Lifer in GA.... 12 MPG all the way home in my truck means I am towing over 10K pounds with trailer... THERE HEAVY!!!

How about for a a3 with auto allison
How about higher transfer case gears ?
