Please help, I'm confused

Reciently I decided that I wanted to put a lift kit on my truck. First I have this one ordered a 3 inch body lift kit. I want to be able to fit 37 inch tires and still have some room.

Now time for a history lesson (not really), My truck currently has 29 inch tires moutned on a 16.5 rim (dodge D-200). The top of the tires sits about 6+ inches away from my fender well, I've tried a pair of my friends 33s on for size and the fit but there wasn't enough room for them to move around really, only 2+ inches to the top of the fenderwell.

Correct me if I am wrong, people I know don't say how this will work (they say it will)but someone might be able to here.

If i put a 3 inch I move the body up 3 inches, giving me 3 inches of extra space but sence the tires are out of the wells alittle bit it would give you 6 inches correct? This is how I am thinking, I want to be able to do all of the lifting in one day and also put the tires on and start to have fun.

Do I need a 4 inch lift to be able to clear this?

Thanks for any help anyone can offer in helping me (diagrams or pictures will help the most)

A 3 inch body lift will only give you 3 inches, however going from a 29 inch tall tire to a 33 inch, only adds 2 inches of rubber inside the fender well.

Word of caution body lifts are not the safest way to lift a truck, a 2 inch body lift is all I would go and would never go 4 inches, you will be much happier with a suspension lift.

For off road use keep the weight down as low as you can and use rubber to get the pumpkins off the ground.

Just my .02 cents.

To go from a 29" tire to a 37" tire is going to take alot more work then you think.

(37-29)/2 = 4

That is how much you will add to the radius of the tire. You would need AT LEAST a 4" lift. I don't like body lifts at all. In almost every state more then a 3" body lift is illegal (and there is a reason!).

Now don't forget that when you lift the body it is only going to go up. You will only gain clearance at the top of the tire...not the back and the front. Turn the tire and see if you have 4" of clearance from the tire to the fender in the front and back. You won't get much more when you lift it.

Most likely (unless you lift it 8-10") you will need to trim the fenders. I am running 36" tires with 3" of lift on my 71K5. I had to trim the fenders a good amount and I don't have any room to spare (snow chains hit the fenders).

Now on to gearing.

lets pretend you have 3.73 gears now.

(29/37)*3.73 = 2.92

Your gears will now feel like 2.92 gears. That SUCKS! You will have no power at all off the line with that big heavy truck! If you have a stick you will wear the clutch out real fast and if you have an automatic you will overheat it and destroy it.

(37/29)*3.73 = 4.76

That is what gearing you would need to have for it to handle the same. I don't know what ratios you can get for your axles but often you can get 4.56 or 4.88. I have 4.56 gears.

At least you have a 3/4 ton...the rear axle should hold up to tires that big...the front will be borderline (you will brake the front if you are hard on it!).

Thanks for the help! that really explains alot.

My old truck i'm not woried about the gearing, I have a 4.11 with a spool in the dana 60 so that doesn't worry me. I'm just doing this while I build the suspension lift (the don't make them unless you know a place that specializes in 2wd kits).

My initial goal is to fit some mosterous 48 or 52 inch tires on the truck... (I know the lift is going to be huge, it isn't going to be a daily driver, just a weekend warrior.)

Thanks again,
Eric
