33X12.50R15 on a 98 K1500
 
I have a 1998 K1500 4X4 with ifs and was wanting to put a set of 33X12.50R15 on it. I have a set of Outlaw 1 15" wheels to put on it so it will be dished out. I was thinking about just putting the leveling kit on the front and doing a 2" block, add a leaf or shackles on the back. I was wondering if someone might be able to tell me if this will work or give me a cheaper or better way to do it. I have the stuff to do a homemade 3" body lift but I just don't know how to extend the steering stem on it. So if someone might even be able to help me with this I would greatly appreciate any advice on these topics.

do a 3 inch body lift. i got the same setup and it looks pretty good. still looking for my set of rims and tires for it though. i looked into the leveling kit too. but after that im pretty sure youll have to get it aligned. im still thinking about getting a 3 inch suspension lift. but if you dont like the frame sticking out dont do the body lift but it don't look bad painted black

I have a 3" lift (not body) and I really like it. I will be getting a set of 33x12.5 this summer and i know that I am going to have to trim the front bumper back just a bit for turning clearance (I have already had a set on the truck to size it up). I am debating about spending the money and going to a true 4" lift so that I don't have to do any cutting, not mention the extra height wouldn't hurt.

I have a friend with a 3" body and he still had to trim his front bumper to fit his 33x12.5 tires but the truck looks really good (that coming from someone who is not a fan of body lifts).

The tires will fit with the blocks in the rear but they will not fit with just a leveling kit, you will need more than that. It might work if you get a different torsion key and turn up the t-bars (depending on how much you are willing to turn them and should turn them while keeping a half way decent ride). But you will still have to trim the front bumper a little.

Basically you are going to have to do a little bit of trimming no matter what to give your self some breathing room over bumps and things.

Good Luck!

If I did the torsion keys would I have to have it realigned? Also I am going to do the body lift but I am using 3" tubing for the blocks with longer bolts and I have almost everything else. I just don't know how to extend the steering shaft. I am on a very limited budget that is why I am trying to do this homemade lift.

6mins2live 07-02-2009 07:43 AM

Yeah I couldnt help you with extending the steering shaft. That is why they make the kit. I have honestly never looked at it so I dont even know what it would take to make one.

You would have to get an alignment with either turning the torsion bars up or replacing the torsion keys. But you should pay much for that.

gpet6669 07-02-2009 12:39 PM

I have no idea what you guys are talking about, if you trim and turn up the bars a little bit you can fit 35x12.50's with a decent wheel offset. I know because I had them on my truck and decided not to trim. (As a result they ended up rubbing and bending the fenders until they cleared)

(Don't ask me what the offset is on my wheels because I don't know what it is and I will not take on off just to measure it)

6mins2live 07-02-2009 05:24 PM

35's??!!! I guess you could "fit" them under there but I am guessing you would have serious rubbing problems if you didn't have a crazy offset, and if you did any off roading you would be smashing your fenders up all the time. My tires come close to hitting the fenders as is.

I guess I just like me a little bit of clearance to move around a bit.

gpet6669 07-06-2009 10:16 AM

I miss typed, NOT 35's! No but 33's can fit pretty easy. Like I said I had a set of 33x12.50 BFG M/T's on my current not lifted or level'd truck. Just a little bit of wheel offset and the right amount of torsion bar adjustment and away we went!

Thanks for pointing out the typo!

6mins2live 07-06-2009 06:12 PM

Oh ok! Now it all makes sense. Yeah you can fit them but like you said it will hit. I just prefer to have a little room i guess.

I was thinking there is no way lol.

gpet6669 07-08-2009 10:10 AM

Yeh, no way to do 35's on stock syspension unless you are willing to do a lot of cutting! Like the whole truck being cut up.

HMMM, we may have an idea!

6mins2live 07-08-2009 06:03 PM

Yeah that would look pretty interesting! Now I wanna see it.

buttdixo 07-09-2009 07:08 PM

I would do leveling kit and stay away from cranking torsion bars. I personal don't like body lifts cause the visibilty of the frame sticks out way to bad and then the gap in the wheel wells. Just me though.

buttdixo 07-09-2009 07:10 PM

You should always get it aligned after any lift or playing with the torsion bars.

farmer12091 07-10-2009 10:20 AM

that would be a sight seeing a stock truck with 35's wedged underneath it

6mins2live 07-11-2009 10:46 PM

buttdixo - I agree 100%

farmer - that with the fenders cut out to make them fit... i have got this sweet mental picture going...

gpet6669 07-13-2009 01:09 PM

Yes Yes Yes, I think we have the plan layed out. Cut up a set of junk yard fenders, get a set of crappy steel wheels and make them bead locks, and put a set of 38's under a stock truck. This would make one hell of a hill climer! Now I want to do it!

Swap the fenders and tires and go wheelin' with a not lifted 38" tire truck. That thing would look so mean, I bet it would look a lot like a CORR truck or trophy truck!

Any one got a set of extra fenders they would be willing to donate??

6mins2live 07-14-2009 05:36 PM

Mmmmm... I am thinkin i am going to have to start looking for a set of fenders rusted out fenders to cut up. My roommate has a set 35"s I could probably use for fun. Then I can take that out to the sand dunes and see what kind of looks I get. Drive it down stock and then swap out the fenders and tires... mmmmmm...

I LOVE those CORR trucks!!!!

gpet6669 07-15-2009 10:38 AM

The only thing I see a problem with is the fender wells, my 32's are hitting the fenderwell in the front as it is. (I think I have my driver side t-bar sagging on me)

But the back should clear a set of 35x12.50's pretty easy.
