03 2500hd questions
 

I bought this truck new and finally I'm getting around to modding it a little. It is a single cab long bed work truck package. It has the factory 2in lift on it already.

I plan to crank the torsion bars on it, but what size tires will I be able to fit? I wanted to do 33s, but I have a feeling they won't fit.

What are some good shocks for it? I feel it is time to get new shocks. It has 160k miles on it right now.

I think that is it, but I'm sure that I will have more later.

Thank you!

Bump

I am going to order michelin ltx at2s for it in the next month or so. What size should I get? I would like 33s, but I guess I can settle for 31s.

Re: 03 2500hd questions
 

You can get 33's under there, I have an '04 2500HD with the torsion bars cranked and while i currently have 235-75R16's on it I'm replacing them with 285-75R16's. I would like to add, however, that cranking your torsion bars can ruin the ride, it is a lot rougher than stock suspension or any suspension lift and for me it just doesn't feel right. The previous owner did it to the truck I purchased and I haven't got around to fixing it yet. I would recommend using a Kryptonite leveling kit or something similar if you just want to gain a couple inches for 33's.

Awesome! Tha k's for the reply. It rides rugs now, o can't imagine it any worse! Lol I will more than likely go with a leveling kit, I want to stay away from cranking the torsion bars so I don't end up with weird wear patterns. I am glad I can fit 33s under it! Should look mean! I am going to have me wheels painted a really dark gray too. Can't wait!

What is a factory 2 inch lift, I've never heard of this. How can you tell if a truck has this option, is there an RPO code on the glove box list. I also have a 2003 2500 HD regular cab truck.

Re: 03 2500hd questions
 

It was an option on the paper when I went to ordered the truck, I'm not sure if it was a dealer option or not, because I don't see it on any of the options lists. It does sit higher than a stock 2500hd. I will look into it a little more.

Re: 03 2500hd questions
 

Does your truck utilize a rear lift block? I have seen new trucks in the past on a dealer lot with an aftermarket lift that was installed by the dealership.

Re: 03 2500hd questions
 

There are some that say the 4wd's use a factory lift block on the rear springs, and that is where the difference in height between the 2wd/4wd trucks come from. The front is higher from the Torsion bar front end. I can't confirm it, but I've heard it from multiple sources.

Re: 03 2500hd questions
 

I have seen 2 inch lift blocks on 1/2 ton models but never on a 3/4 ton. My 03 2500HD 4WD does not have lift blocks, neither does my neighbor's or my best friend's trucks.

Re: 03 2500hd questions
 

Crank the t-bars. I did that on my 04 CC 2500HD. And BFG 285's fit nicely.

By the way, BFG AT's are THE WAY to go. I had Revo's on there when purchased...they barely lasted 40k miles. The BFG's have 60+K on them, and still going strong. and MUCH better in rain, snow and off road. Just saying...

Re: 03 2500hd questions
 

Yeah I looked and there is no lift blocks. Could it be a more arched spring in the rear?

Sorry for the late reply guys, been super busy and haven't had the truck.

Re: 03 2500hd questions

Re: 03 2500hd questions
 

Actually this helped me a lot! Thank you, now I know I'm not crazy.
