Whose doing it???


If you are, and like it, tell me why. If you are, and don`t like it, tell me why. If you`re not, and want to, tell me why. If you aren`t, and would never do such a thing, tell me why. :deal: :wink1:

im not, i dont want to, but i would if i had a rig with a 700...

3.06:1 1st in the trans
2.1 or something low in the tcase
4.56 in the axle..

29:1 gear ratio? sounds good to me!
 
In 4th gear, cruising the highway at 65, 4.56's and 35's will be nearly identical to having 3.73's with stock 29 inch tires. 1966 RPM with 3.73's and the stock tires, 1991 RPM with 4.56's and 35's. :cool1:
 
I wish I had 4.56's. I just put on 35"s with my 3.73 and now can barely get into OD on the highway. Especially with the heavy burb, I think 4.56 will be perfect.
 
That's what's in my crew cab, perfect match. :thumb:
 
I ran that exact setup for years. it's perfect. good low end power and still low rpm's on the highway.
 
i have 4.10 in my jimbo. wish i had 4.88's though, my 35" tires are nice, but im goin with 38" tires, so 4.56 i think wont be enuff. on hills, my truck slows down pretty bad.
 
i used to run 3.73s and 35s and i thought that was decent. 4.56 would be really good. i was originally planning on 5.13s and 36's since u got overdrive with 700r4, but ended up going bigger. id almost suggest 4.88s simply cuz u got overdrive
 
Interesting, I'm finishing my rig up now with a similar combo, 4:56 700r4 40's and 208 until I can get my doubler built then out goes the 208. Only I wont be running mine on the highway.
 
I have a set of Yukon 4.56s for a 14sf w/ install kit I am willing to part with....
 
I've been running 4.56's with 35s and a 700r4 for 8 months now and love it, power off the line, good gas mileage if your easy on it because of low rpm's around town, and doesn't kill you on the highway, I can cruise at about 2200 rpms all day. i debated wheter going 4.10's or 4.56's and 4.56's was the right choice.
 
works great. i loved it. ran 4.56 and 33's for 2 years. overdrive gives you a nice crusing rpm. dont expect to cruise at 85 all day long though. i run 5.13 and 37's now, it's pretty close to the same tire/gear ratio.
 
Go 36s. I went through 1 set of Hummer military 36 inchers, one set of SuperSwamper tsl 36s in my 77 Jimmy with 350/465/205/4.56. Perfect match. My latest set of tires are 38.5 groundhawgs and I could definitely stand to switch to 5.13 gears.

That is the way I'm going. Best utilization of gearing for wide range of use IMHO.
