Are there any gears numerically higher than 4:10 for the AA yet??

I had 35's w/ 3.73's.. That tire is too big with the auto.. It made my truck bog down, raised egt's, and the mileage dropped way off. There's no way I'd put 35's on w/ 3.73's and an auto.. 4.10's at least!

 

i have 3.73, 4.10, 4.56, 4.88, and 5.13's on the shelf for the rear... im waiting for the 4.88 and 5.13 for the front..

pm me for prices.

 

I have 4.10s with 3.15s and I have plenty power.

 

i would suggest the 4.10 that would give you almost the stock gearing of the 3.73's and stock tires its actually like a 3.90 or something like that when i figured it out. i have the 373's and 315's and they work fine for me but i rarely tow over 11k. i do most of my highway driving when towing at 65ish and there is no worries, you do have to pick it up to 70 when you start the hill if you wanna stay in OD but it climbs just fine. i do have some engine mods so that helps too. if your truck is stock and near a SO i wouldnt even bother with the 373 and 315's. even though they work fine now i'm going to a smaller tire to get some of the in town mileage back.

hope that helps

well 4.56's would give you roughly the same final drive ratio on 35's as a stock truck on 32's with 4.10's. So if you wanted the roughly the same rpm vs speed that is what you want. 3000rpm with 32's and 4.10's is 101mph. 3000rpm's with 35's and 4.56 is 99MPH

 

stock tires are 31's right?
