It entirely depends on what stock gears you have now. If you have anything higher than 4.30s I wouldn't bother. If you have 3.58s you'll be lucky to get it down the street with 33s.NC's BeefTaco said:What's the biggest tire that anyone is running with a 2.7 without regearing and how bad is your gas mileage and speed? Just wondering if it's possible to go over 33"s without regearing from stock gears.THANX.
Hey Hytenor, I'm the guy with the 3.91's, thanx for your help on the other post about gears. So, is it possible for 33's and the 3.91's?THANX.hytenor said:It entirely depends on what stock gears you have now. If you have anything higher than 4.30s I wouldn't bother.

Those who say they can run the big meats with stock gears with "no problems" are full of it...or they have convinced themselves that Yugo performance is just fine.
Big tires and improper gears just wears stuff out faster; clutches and ATs don't last long when the gearing is wrong...and then there's gas mileage...
I've seen it done but not with an AT, only a 5sp. the guy didn't have use of 5th gear unless he was on flat road w/o a head wind. The AT might actually get damaged with that much of a size change (28s to 33s) as it will be constantly wandering through gears trying to find one that works...but it can't cuz there ain't one.NC's BeefTaco said:Hey Hytenor, I'm the guy with the 3.91's, thanx for your help on the other post about gears.

I think I posted prices on the other thread but figure around $300+/axle for the ring & pinion and a master install kits from PORC. labor will varry. If you can pull the rear 3rd member and take it and the parts to a reputable gear specialty shop I've seen prices from $150-300 posted here. If you just drop off your truck add another $100-200. Shop around for best labor rates but don't pick a shop just because they quote you a cheap price; make sure they know what the heck they are doing and guaranty their work. Have the rear axle seals replaced (sense the axles are pulled) at the same time for around $7. You can get your speedo pretty close by swapping speedo drive gears but you'll have to drive it with the new gears/tires to establish how far off it is first.NC's BeefTaco said:Okay, thanks hytenor. Say, could you give me some figures on what it would cost to regear, and what the best gears would be, and how much difference there would be in regearin for 33's and for 35's.Thanx.
