    1986 K30 Big Dooley in need of bigger tires.

    Thanks for the info highdesertrange. So my question now is, is there a way to push the inner wheel out from the frame some? Maybe get longer studs and the spacers with holes you warned me about? Maybe an inside rim with more of a negative offset? I'm not gonna be using it as a tow rig, mostly...

    1986 K30 Big Dooley in need of bigger tires.

    This is my first dually so bear with me. I was thinking that I could put a 1" spacer on the inside tire to push it away from the frame then another 1" on the outside tire to space them out. Then since they are even with the front put a 2" up there to keep them even. Will that not work? Is there...

    Thanks! It has definitely been cared for. The crazy thing is I believe it's all original metal too! I was actually looking for a 69-75 Blazer when I ran across this and could not pass it up! Still down to trade for one if anyone has one in equal condition! Here's the front undercarriage

    Thanks for the measurements! Hmm well, if I have to have spacers. Could I put 2, 1" on the back and a 2" on the front? The truck isn't gonna see much load. The most would be about 3,700lb boat. You know a good spacer manufacturer?

    If you don't mind, that would be awesome! I found where another guy had bought them, and measured them around 34.75", which is weird because all the other tires that are in the 900R16 were measuring 36.3". Hopefully they aren't too much wider, cause I might run into problems. I went ahead and...

    Yeah, that's why I want to go with the 900R16 which is a 255/100R16 no wider just taller. Just don't want to waste money on tires, that I'm gonna hate.

    1986 K30 Big Dooley in need of bigger tires.

    No still no tires yet. I've been working on other upgrades while I search for the right tires. Carb rebuild, Radio and speakers, sound deadening, rewiring the halogens and spot lights, and a Dakota digital gauge cluster. Now I find myself ready for tires and still no definitive answers! So...

    Supercharging a 454 questions

    Now that im researching the ignition retarder, I think I might just go with a TBI conversion kit. As it has one built in and a lot easier to tune. Any big cons to the system? I'm kind of a noob when it comes to passenger vehicle engine modifications. So any and all information is helpful as I...

    Supercharging a 454 questions

    Ive got a 1986 K30 dually 454/TH400 combo with 3.73s. It has 27,000 original miles. I was thinking of bolting on a supercharger for some easy power. I know ill need a new carb and some free flowing exhaust. What else should I look to upgrade? What are some carb suggestions? What are some...

    Thanks, it has 27500 original miles. It was an emergency response vehicle for a fire department. Everything looks good up front, real solid. I'm gonna go with all 6 tires. Just not sure how or if I can fit all of that tire on the rear.

    1986 K30 Big Dooley in need of bigger tires.

    I just recently bought this 1986 K30 dually 454/TH400 with 3.73 gears. It has a Rough Country 6" lift. I believe it has the stock wheels and tires. It desperately needs bigger tires to fill some of the gap. I've done some searching and seems that it can fit 35" tires. I'm thinking of running...
