Running a higher gear in the front

[Bonedigger]

Back in my mud drag racing days we ran a higher gear in the front end to help keep the truck straight in the mud. Do you guys think it would help in the rocks or hill climbing or would it just tear up the front end. I ran 4.88 over 5.13 with 450hp in my truck for about 10 years and never broke anything because of running them like that but that was in the mud and around the pits.

Although it would be hard on the tcase, it helps big time in the RC world. Keeps the front tracking straight when you mash on it.

When you go around corners, the front already travels a farther distance than the rear, so it naturally binds.

For a straight up bouncer/hill climber, I think it'd be worth a shot

Never know till you try. People will say you are crazy and it will never work, but as soon as it works it will be the next big thing!

On my CJ and then the Mazda, i ran 5.13's in front and 5.38's in the rear due to a goof up on my part.. always noticed the rigs would crawl like a billy goat, but then again i did always run creater tires
Only time i noticed binding was on hard packed ground, or driving to/from the trailer. I got used to driving in front wheel drive and only engage the rear when needed. I was running a built D300 with a stock case and never issues.

For bouncers, i too think it would benefit... but what do i know about bouncing

It will work, as long as front is higher it just spins the front tires a lil bit and be no worse than doin a "front dig"
I done it for bout 3 years in a chevy short wide with 38" TSL and a big block and 4sp

In the cab truck I have now I run 4.56 rears with 46" cut turfs an 3.73s in the front with 37" tires. I've never had any problems. If you do the math there close to the same ratio with the tires figured in. I've had it out on the pavement running around my house and it never bound up. :****:

Most likely not break the t-case if you run a 205 with big joints.

I've got a buddy who does the opposite 4.56 in the front and 4.10 in the rear,done this on his last two rigs since he is to lazy to regear the 14 to match the 60 and it has held up fine in both of them.
