Tire size on lowered c20

Hey guys I have a 1984 c20 Scottdale with the Detroit diesel. I have a couple questions.. I did a 3 inch hanger and shackle lowering on the back and kept the front stock looks good. I'm running 285/65/17 (33inches) I'm really wanting to lower it more and was thinking of doing a axle flip kit on it. Would the tires rub on the bed? I also pull a trailer with my car on the back every other week. Is that even possible? To pull and still be that low? Need yalls wisdom and advice! 😊

Re: Tire size on lowered c20

Before I cut mine up I ran shackles and hangers and pulled 3 or 4 leaf springs from the bottom of the pack. Got a 5-6'' of drop. The spring back is so thick if you do a flip kit you will be in the 8ish inch drop range. You will absolutely need a c notch and that would seriously inhibit your ability to tow.

OK good to know I believe the lowering ones I received were for a c10 and a little different. Maybe I'll look into a lower hanging kit and removing a couple leaf springs.. And would be able to tow.. Orrr should I go back to factory hight and do a axle flip kit???

Not to be too much of a smart, uh, aleck, but I think your last picture answers your own question. It doesn't appear that your 285s have much room to move before they're going to be pulling your fender trim off for you. A narrower tire that can tuck behind the fender lip would probably allow you to get another inch or two.

On the "opinion" side of things, a 3/4 that still tows and hauls needs to have suspension travel. Sometimes the good answer is to have things in proportion, rather than trying to go as low as you can. Good sideview pictures of your truck loaded and unloaded (not towing and towing) would help us give subjective answers to what you can do. Without seeing more, I would say you can't lower it further in the back and that an inch lowered in the front front might be all it takes to give it good proportions.

Re: Tire size on lowered c20

So if I did not tow my car anymore think I could go lower or still running into the problem of the tires to wide?

Nope. Still going to make contact most likely w/the wheel set-up & the tall tires.

Building a small, high rpm engine with the perfect bore, stroke and rod ratio is very impressive.
It's like a highly skilled Morrocan sword fighter with a Damascus Steel Scimitar.....

Cubic inches is like Indiana Jones with a cheap pistol.
