CUCV Dana 60 axles

[Zukini]

I'm looking to upgrade axles on my M1009 to dana 60's out of a M1008. Just wondering how driving around town and on the interstate is with the 4:56 gears. I want the beefier axles but I still want to be able to run it 60-70mph if I want. Would like to hear from you guys that either have done this or are driving the trucks. Thanks!

Can't have your cake and eat it too. You'll be limited to 55mph unless you put taller tires on or an OD transmission in.

Yeah, thats what I figured. Guess its time to start looking around for a 700r4.

NV4500...the only way to fly...

That's just NOT TRUE.

When I run my M1028A2 at OR BELOW 60 mph, I get 15 mpg.

When I run my M1028A2 AT 65 MPH, I get 10 mpg.

I did this for three days last year when I drove it from PA to CO...

plug in any numbers you want - but with 4.56 gears and 16 tires, you can go 65 mph SAFELY and stay below the 3500 redline

though the more I read about the 6.2L, the more I think that redline was for all the guys who drove them in the military - not the actual limit of this venerable engine - I have read several articles and even posted most of them here on SS

40" tires would do it.

You might have done that but I can tell you from experience that at 55mph it SOUNDED like mine wanted to come through the hood! And she did NOT want to go any faster!

Look for Dana 60s with 3.73s or 4.10s...or a 700r4

I like the 40" tire idea...and the NV4500 idea....

oh wait



I was running 11.00R-16 Michelin XZLs with a 700R4. That was a good combo too!

FWIW, I'll be running 37" Goodyears. My concern is turning too much RPM's and damaging the motor.

I dumped Nv4500 in mine, I do 70mph No problema, I know the motor isnt screaming at me the calc. with 4500 and 305-85 says I am somewhere around 2300 rpm
