what size tars you running? how you like your 4.30s?

 

my tars are 275/45/20. Like em pretty good.
The only thing i miss is how long i could stay in 2nd gear. 2nd only lasts to about 75 now but on the plus side, 3rd gear pulls a lot better than it did before.

 

im on 275/45 too but im goin back up with the truck and i will be running 305/50 but hopefully it will be about like stock maybe alittle better... thats all i want

 

has anyone run usa standard gear? thats all i can get in 4.30 right now for the rear.... yukon and aam areboth backordered and out of stock and i need the truck fixed asap.... i got prices on the gear true trac and a girdle but it should be better and it will be nice to have the truck driving right again

im been dealing with rons.... the 4.30s are out of stock and on backorder.... im thinking 4.56 now with a 32" tire it should be ok

 

Motive had a bad run of gears about 5 years ago and had a recall on them. I set up a bad set for a buddy of mine. I have since set up 4-5 sets of them with no issues.

 

I'm running 4.56's with 305/40/22's and I turn about 2300rpm at 70mph so it's not too bad, however the down side for you may be that it's a pretty tall tire and the fact your truck looks to be pretty low, which may cause tire rub issues at or close to lock. Also the larger tires will be somewhat heavier than something shorter that you were probably going to run with the 4.30's.

Good thing is you can get AAM gears in a 4.56 ratio.

 

right now my truck is like 5/7 compared to a 2wd.... but its goin back to stock height just leveled on 305/50/20 nitto terra grapplers... it wont rub a bit... and the gear will also help of the weight and taller tires... im goin 4.56 just waiting on ron to call me back

 

4:56's, you'll love em
