Gear ratio for 35" tires

Chad H · March 30, 2004

Hey guys,

I finally got my 4" suspension lift with 35" BFG a/t's last week. But, the mod bug is hitting me again really quick. I took this truck offroad a little and it performed really well. But, with 3.73's its hurting its ability. Now, here is the deal, I am fixing to install a dual shock set-up all around w/ a steering stabilizer and a limited slip. I need some gears also. What ratio do ya'll suggest? I drive this truck everyday and gas mileage doesnt bother me too bad. I was thinking of 4.56's but I dont know. Need some suggestions for that an a good limited slip.

Thanks,

Chad

Great googly moogly you have put more mods on that truck in the shortest amount of time I have ever seen.

He!! of a good job! Looks awesome

I think that 4:56's would do you very well off road, but I'm no expert....(They will chime in soon.)

Once again. Great looking rig, thanks for the pics

It looks great. For gears, look at this chart:

Looks like 4:56 or 4:88 would work for 35's.

You should really put those pics up in the picture section too.

Show off that beautiful blue paint man!

That's going to be my next trucks color.

Hey there! Nice ride. I just got done putting 456's in my 03 Hd. I am also running 35's. At about 75mph the tach is at 2500 rpm. It is right there where the power is. The 456's are perfect. I will post some pics of mine when it stops raining.

My truck stock had 4.10's in the rear. I put on a 6" Pro comp lift with 35's. For me I put in 4.88's and it drives like it was stock again. I can tow heavy trailers and the truck doesnt feel like its winded anymore.

I say 4.88, you get lots of torque and thats good if you're doing low RPM off roading.

Did you really just post in a thread thats almost 5 years old?

HAHA, yes, yes he did. I agree though. I would do a 4.56 or a 4.88. I am leaning towards a 4.88 myself b/c I know I am going to a 37 when these wear out.

4wheelparts.com has a gear ratio-to-tire chart. the chart also shows optimal gear ratios for a daily driver, towing, and something else. pretty interesting i thought...

Hello all, newbie here, I have been lurking for a while but this is my first post. I have been reading about your lift and tire combos. I just bought a 2001 Sierra 4.8 4x4 w/ a 6 inch lift and 35 inch tires. The truck drives excellent and it is almost perfect mechanically, except for a small power steering leak. Last week I took my family to Big Bear and it was falling on it's face on the freeway. It shifts back and forth from OD to 3rd when I go slower than 75. At 80 it would hold OD but it would still bog down. Up the mountain it had to keep it in 2nd so it make power. I bought the truck from a used car dealer and they did not have the original window sticker, so I am assuming that it has 3.73 gears but I don't know. This truck is mainly to be used on the highway to take me and my family to the desert every other weekend then launch and retrieve my boat when I am there. My boat is already there so I won't be towing much, if at all, and it will not be my daily driver or will it ever go off road, I have a jeep cherokee for that purpose. My very ignorant question is, should I think about regearing it to 4.56 or should I just save the money and drive in 3rd on the freeway to hit the powerband? Thanks in advance for your help and I apologize if I sound lame...
