    I know a guy who is gonna sell me a 14 bolt really cheap with 4.10 gears, I want to run 37x12.50 SSRs, I am wondering how do you guys think this will be? My present rears are horriblly geared and I am really sick of it. I think they are probably around a 3.08 with the 33s I have. I have always had to start out in creeper first on my SM465 sicne i bought it. I replaced the cooked 305 with a 350 so that should help in the torque department.

    4.10's would probably be good since you have a SM465. I have 4.10's and a TH350 automatic and for what I use my truck for I wish it was lower geared. But it does pretty good like it is, I run in 4-LO most of the time with the hubs unlocked when I'm offroad. If my math is right even when in low range (first gear) I wouldn't be as low geared as you when you are in high range (first gear) /forums/images/graemlins/shocked.gif.

    I was looking to run my 3.73s with some 37" MT/Rs. This should help me with my hwy RPMs.

    I think 4.10s and 37" should be fine. Depends on what you do off-road.

    5.13's. sooner or latter you'll be at a bigger tire. if you are going to regear, go as low as possible.

    Yeah but this guy is giving me rears already geared to 4.10 and I don't feel like spending the money to regear.

    i'm runnin 4.10s and 36s right now and it's a heck of a lot better than the old 3.73s were. and as soon as someone buys my old 14bsf and 4.56s for it i'll be buying 4.56s for the new detroited 14bff i insatlled a week ago and installing the front 4.56s.

    4:10's and 37's should actually feel better then 3.08's and and 33's:

    new tire/old tire * old gear ratio = new gear ratio

    this will calculate the gear ratio needed to get the same RPM band as with the old tires so:

    37/33 * 3.08 = 3.45

    4:10's should be great around the street and good offroad with your granny low. I had 37" SSR's th350 and 3.73's, a little slugish off the line but great other then that. hell I even had enough power offroad to explode a transfer case yoke.
