Well i put the summit headers on, cut the cat. off, put that mopar performance K&N round filter setup on, 52mm holley TB and now im lookin for gears. I do a lil bit of highway driving not much just in the 50 mph ranges sometimes im probably gonna look for sumtin in the 370's like 373's? but i dont know where to find any. Can some one help me to find gears for my truck. thnx guys!!!!

 

go 4.10's

 

Gas mileage? Highway driving? i dont know about that??!!!

 

most important question is what size tires are you planning to run ?
285 - 305-315'ish (33-35) would need 4.10's.
35 and up likely need 4.56
there is a 3.90 but i wouldn't bother with it.
i don't think there is a 3.7x for 9.25

 

I have 17" stock oem rims from a newer dodge. the tires are gonna be 275/60/vr17 ECSTA STX im lookn for some low end guys the gearing has to acceptable on highways but i want a better push off the line help me out

 

I would still say go with 4.10. I ran 4.10's with 265/75/16 for awhile, and saw very little loss in highway mpg. These trucks are so heavy, you really need 4.10's. 3.90's is about your only other option. Don't even waste your time going from the stock 3.55 to a 3.7x (if it even exists for our axles), it would be a waste of money. I think 3.90's would still be a waste of money too, but if 4.10's are too aggressive for you, that is going to be your only other option.

 

3.92 isnt bad, no acceleration, but LONG legs.

 

Sounds great then i mean they are really heavy trucks and i shouldve probably put like a 350 in a s10 and woulda been better off but this is my first truck and wanted a challenge. Were can i get some 4.10 gears at???

PS: I want my rearend to be posi. thx guys!!!

 

go to www.4wheelparts.com. i just ordered 4.10's for my 98. it was a total of $500.00 for the front and rear gears and master install kits. it also comes with a new carrier for the front to fit the 4.10's.

good luck

 

Or you can go with a thick gear for the front, and retain the stock carrier.
