Benefits of a 700R4

I was hoping to get a little input on any benefits people have experienced. The one benefit I'm hoping to get is driveability on the freeway. My truck has 456 gears and I'm trying to keep my bottom end but also gain on the top end. I don't plan on towing with this truck and in the next year plan on rebuilding the motor or replacing it with something the produces around 350HP

Any input would be great! Thanks

Well, first off, depending on how big you're tires are, I think that the gearing is way too low. Unless you have 35" tires or bigger, you really don't NEED gears that low. Secondly, a 700r4 has a deeper first gear than a th400 or th350, so you'll have even more kick off the line than you do currently. If you are running up to 31 inch tall tires, I'd recommend re-gearing to 4.10 or 3.73 axle gears. When you add the 700r4 you'll gain back some of the low end kick that you like. It may not be exactly the same but it'll be close & you'll gain tremendously from the OD on the 700r4.

HTH,
Buddy

Re: Benefits of a 700R4

Re: Benefits of a 700R4

Thanks for the input, That's what I thought but wasn't sure. My tire height is only 29" so that combination would make it even lower. I may have to go with 373's

Thanks

Re: Benefits of a 700R4

I'm running 373's with my 700R4 and I love it. I had 3.08's and it was horrible. Yeah the rpm's were waaaayyy low, but there was a lot more downshifting and such whenever you encountered a hill. I think 373's or 4.10's with a 700R4 is perfect..............................Bamm24

Had mine installed by a trusted pro. He felt that 373's were the best mate to a 700r4. I'm very satisfied with mine!
