I am looking to put 37's under my 95' 2500 4x4 and looking for opinions on kit's. Not interested in going over 6" either. Best I have seen so far is the 6" RCD?

 

5.5" is all you need, im using a 2.5" spacer and fit 35s no problem

 

This is my friends 01 1500. He has a Rough Country 5" lift on 37" Super Swamper TSL. He had to smash in his wheel wells a little big infront of the doors so they didn't rub when he turned but his tires are pretty wide also.

a 2500 is taller than a 1500 and he had to bash in the wheelwells because of the lack of wheel backspacing, although, if he didnt use those wheels, his tires would rub on the control arms.

 

im runnin a 5.5 inch fabtech.... im thinking about upgrading to 37s when my 35s wear out but i know i will have to get different wheels too because the backspacing wont be enough

 

Sometimes.

A 2500 is definetly taller then a 1500 when they both have the stock suspension, this is true. But when you remove the stock suspension, and put on a 5" lift for example, the 1500 and the 2500 could potentially sit the same. It depends on the type of lift and the manufacturer of the lift. Some are designed to give you 5" more then the stock suspension measurements. Others are designed to give you 5" over some other more generic measurment. Where the measurment comes from is based on how the lift was designed and engineered. This is when the stock height difference between a 2500 and a 1500 can be lost, and a 5" lift on one will be the same as a 5" lift on the other, making both the 2500 and the 1500 sit exactly the same height. Additionaly, an advertised 5" lift from one manufacturer could come out on your truck as 4.5" over what you had from the factory, and from another manufacturer, it could 5.5" over what you had from the factory. But both were advertised as 5". All i'm saying is, once you remove the stock suspension, and replace it with an aftermarket one, all bets are off as to weather a 2500 will still be taller then a 1500.

I agree though that the wheel backspacing is as important as the lift, maybe more, when it comes to tricky tire clearance. Care should be taken in selecting the wheels you plan to run when building your rig.

 

Thanks for the input guys, any brand prefered over the other? I am looking at running wheels 17x 9 w/ 4.25 for back spacing 37x 13.5 x 17 tires ..5-6" lift need a little extra hieght because of the wheel base, this will be a trail rig eventually rock orientated.

 

i have a few questions then, not to argue, just to clarify.

Which companies use this "genaric" height measurment?

If a 2500 is, say, 3" taller than a NON offroad 1500, then a 5.5" 1500 lift would turn into a 2.5" lift on the 2500, which would basically be a 2.5" coil or spacer to level the truck out (my #s are off, but im sure you get what im trying to say). it just sounds like it would be false advertisment.

 

Mine is a 4.5" Tuff Country. You can see my 36'ers in the pic in my sig. The dude I bought it from had some 37 super swampers on a diff set of wheels I have laying out back. Both seem to have miles of clearance, but unfortunately I have no idea what the backspacing is.

I could check for you though if someone tells me how to check backspacing.

 

Best lift I have ever seen in my life was the Dick Cepek 6" lift I helped a friend install on his '97 2500, back when I had a '98 1500 RCSB 5.9 4x4. Made me wish I had a 2500!!!

Pricey, but the most solid lift I have ever seen...
