i am looking to get new rim and tires. i know wat rims i am getting. i was thinking of getting 37's 37.5's or even 38's. People have been telling me that if i get 38's i have to change the gears in my rear. How true is that? i dont want to have to do that. thats why i am wondering if it has to be done before i buy 38's. if u could plz help me i would appreciate it. thaks

 

You don't HAVE to regear, its just going to bog the truck down, if you can deal with it u don't have to. Might put a pretty good bit of extra strain on ur trans.

 

You will lose a lot of power but more important will be the strain on your tranny. I am running the stock 3.73's with 35's right now but that is only because I bought the truck this way and I have a lifetime powertrain warranty. My last truck I had 37's and 4.88's. You can get away with 4.56's and 37's - 38's but for your enjoyment and the longevity of your tranny you want to go with 4.88's.

 

also what's your suspension setup?

 

If you go larger than 35's you really, really need to regear.

 

But the transmission will NOT explode, just won't last that long.
Hellfar, i'd do it. my weak tranny(car transmission) and 35's was doin fine for like a 11k miles, i just got tired of it being so slow.

 

i have a 6 inch skyjacker kit. with 35's now. i also have a 3 inch leveling kit. my tires look to small dint know if i should get 37.5's or 38's. How hard is it to change the gearing out?

 

oh ok, well either will look great but the 38's could scrub depending on the wheels. regearing is something best left to the pros unless you know what you're doing. if done wrong you could grenade your differential.

 

I agree. Not unless you know what ur doing for sure.

Mine was 250 per axle (500). Plus about 450 for the gears themselves and the install kits.

 

I'll sell you my wheels and tires for near what you will pay for 37's new. These wheels where $3500 new. You can buy these and regear for under that more than likely.

 

I was the same way with my 38's. Then I re geared and I love it.
It is a very good investment. You don't realize how
Much power you lost till u get them put in
