View Full Version : What gears would you suggest?
02-17-2007, 06:57 PM
Once I get my Bronco back on the road, I'm going to start saving for a SAS and new tires. I want to run 35" tires, So I'm wondering what gears would be best to run with them.
I'd be running the truck mostly in Mud, with some trail exploring. Current engine is a 302 with an intake and dual exaust, so I don't have loads of power to be throwing around. I'd like my cruise at 100km/h to be decent, not screaming at 4000 rpm or anything like that.
Should I stick with the 3.55s? or would 3.73s or 4.10s be better?

4.10s you want to get it to close to stock ass possible are you going to run a aggresive tire or all terrian?

Maelthra, Im gonna be going to 4.56 gears when I do my SAS with 35's, if I went with 4.10's with my bronco it would be the same as stock but I want the extra torque and its just that much more weight that little 302 has to turn. I think 4.56's would be better on and off road. If you were to ask the guys a FSb.com they'ed probably tell you the same.
This is Deathtrap not the misses

thanks for the info so far.
With 4.10s on my 33s, I was revving pretty high to be running on the highway, that was my worry for running 4.10s or 4.56s with 35s. I'd like to be able to take my truck on extended road trips without paying an arm and a leg for gas. not that I don't already, but if I could get the cruising rpm under 2500 that would be awsome. And my drivetrain is way too short for a aux. overdrive.
I'm gonna be running a mud terrain tire, probably BFG M/Ts or Swampers.

Go 4;10s you will be good to go up too 40s. after 40s go to 4;56. go with 4;10s will be good.You will find your rpms high with 4;10s with your 33s but will work will offroad.[cheers] :vroam:

If you run 35" tires I would go with 4:10s, will still be able to drive it on the highway without it screaming

I ran 3.73 in my blazer with 35's and and a small block 400. It was not enough gear. I went to 4.56 and found it was just about perfect, except for long highway trips. With a 302 and 35's I would go with 4.56, unless your hitting the highway for trips of 300 k's or more on a regular basis. My cruisinr rpm at 140 kph was about 3500 rpm.
