Hey, I would like to regear my truck for better accerlation, i have noticed quite a bit difference from the 30x9.5x15 tires and wheels before. im thinking about 4.56 gears? And idk if this is a stupid question, but im young and dumb (im 16) would i need to regear my front end too or what? I have a 302, 5 speed, 265/75r16 (32x10.5x16), and do plan on getting a 4" lift and inch taller tires in next few years, and i do moderate towing.

 

Yes, if you have a 4x4 you have to regear both axles. Plan on about $1600.

 

With those tires and your usage, I'd recommend 4.10s. To go to any gear larger than 3.54 on the front end, you're going to need to replace the carrier as well as the ring and pinion

 

4.56's on 33's with your set up I think will be running some rpms you wont like. You do have overdrive though atleast. Personally I wouldn't consider more then a 4.10/4.11. I know people who run 4.56's on your same set up but 38's. For that reason I think 4.10's would be best

 

glc~ is that $1600 includeing someone putting them in because i can do all the work my self with some help.
StrangeRanger~yeah i looked into it a little more and was thinking a lil more towards the 4.10
rclark12~yeah, that makes sense

 

That includes labor. DO NOT attempt to do it yourself without EXPERIENCED assistance from someone who has done gear swaps and has the right tools and gauges.

 

Ya got quite a bit of reading and learning on preloads and backlash for setting up a new carrier.

...and a whole pile of tools to buy or build in order to set up both a Ford 8.8 and a D44 most of which you'll never, ever use again.

 

Don't do it yourself unless you have experience because gearing is expensive and when done wrong you can grenade them I've seen it happen. If you don't do from and rear you'll blow your transfer case . Better off getting it done right

 

If i do it i will have a mechanic or two help me i know quite a few experienced mechanics. but i will keep that in mind i definitly wouldnt want to mess anything up. well if i dont do it myself ill definitly wait a while haha

 

There's alot too it, just make sure you do it with some one who knows what their doing and has all the right tools. It sucks to spend that much money i know, im spending 1400 to get my d60 and 10.25 done. But its really something to bite the bullet on because I could save 500 bucks doing it myself but Id need to buy tools and if they grenade it will wind up costing more any way. Just some food for the thought

 

How would 4.10 or 4.11 work for 37x12.5? i'm eventually going to get I high enough for 37s and would rather not regear it twice :/

 

You need 4.56's with 37's.

 

4.56 is way too big if its your DD. 4.10 like the other guys said I thinl you'll be happy with that.

 

I'd go 4.56 myself with that big of tire. If your starting out with 3.55's 4.10 isnt even worth the change.
