Should I add a 3in Body Lift and sit her on 33x12.50R15 A/T's?

Ive got the money, I just need some opinions.

Its not my daily driver so gas mileage Isn't my concern.

Any body know of any major performance issues with this?

 

You would probably want to add a few more dollars for new gears. The larger tires will make the acceleration slow down, but regearing will keep it performing correct.

For example:
Starting with a 28" tire with a 3.55:1 ratio you would need about a 4.11:1 to be equal.

And yes it would look nice...who doesn't like a lifted truck with larger tires

 

It has 31''s on it now, im not sure what to change the gears to. How much would that cost? Would I just take it to a mechanic to get it done or something?

 

I think it cost me about $700 to buy a limited slip, new gears, and have it installed. The limited slip was a little over $400 if I remember right. I had it done at a shop because it didn't cost much more than buying a pinion depth setting tool.

You can use this equation to figure out what rpm you will need at a certain speed. I built the equation to calculate top speed, but you can just change the RPM parmeter to see what speed it will give you. For example put in 2500 for RPM and then play around with the gear ratio until you acheive an acceptable highway speed. Tire Diameter is in inches.

MPH = ((RPM X 60)/ Gear Ratio) X ((Tire Diameter X Pi) / 12) X5280

If you want it in an excel spreadsheet just PM me your email address.
