gear ratios

[gmc4cw]

what gears are you running with what trans/T-case(s) and tire height.

I have a 700/241 with 4.56 gears and 44's. looking into some different gears and would like to know what works for you.

mine is trail only.

thanks for your input.

 

[gmc4cw]

wow, you are viewing this but not responding. you have a trans and t-case right. you probably have gears in the diffs too. all responses are encouraged.

10b's w/ 3.08's

38.5" MT Baja Claws

SM465/205, 4.56 gears, 37" tires.

If you are looking for deeper gears you are probably looking at a doubler/atlas or a dana 70 rear end.

35's for the street, 38.5's for the trail

 

[JEBSR]

465/208/456's/38.5" Could stand to go with 488's but it does really well as is.

I gots me a 700R4 and 208 with 4.10s and 37s. The gear is too high 3rd revs too high and OD is too low of an RPM. I will be going with 5.13s and a doubler or 3 speed stak behind a NV4500.

700r4/np241/4.10 gears with 33s. It's ok for the way it is now.
I'm going for 700r4/203,205 doubler/5.13s with 37s

 

[Greg72]

If the truck is truly "trail only" there is no reason not to go as deep as possible..... which is 5.13s if you're running a 14BFF.....7.17 (or something like that) if you're willing to swap in a Dana rear end.

I'm assuming you already have a D60 front since you are running 44's.

 

[muddybuddy]

700r4/208 5.13s and 39.5's

 

[onetonbb74]

350/700/203/205/4.10 36-12.5-15 i want 5.13/5.38's and 39.5's

doublers are expensive. What would I gain from a 70 rear end?

This truck has been in overdrive only a handful of times in the last 7 years. not once this year, and only once last year when I was messing around on the road in front of Paragon. Pretty much keep the lever set to 4lo all the time.

would 5.38's be too much? right now I have a 38:1 crawl ratio not counting converter slip. 5.38's would put it at 45:1. not much but a step in the right direction.

If I did a doubler I would like a klune-V since you can mount anything behind it. and its lighter then a 203. my truck weighs enough already. so if I did a 205 behind that it would still be short. with 4.56 gears I would be at 75:1. same setup with 5.38's would be 89:1. not too shabby.

I'm thinking out loud here.

yes its a 60/14 bolt combo. geuss 5.13 is the way to go since I don't feel like swapping axles again.
