4/6 drop tire fitment questions

[1990 GMC]

I'm wanting to do a djm 4/6 drop with probably summit shocks. My main concern is the rear tires having enough room for travel. My fronts are 235/75/15 and the rears are 275/60/15. Does someone know if these will fit with some rolling fenders and stuff? Here are the pics of the front an rear tires:

I know Richard is out there somewhere :looking:

It will be close. I would roll them just to be safe. I have 255/60/15 on all fours- BF Goodrich Radial T/A's. If I carry a heavy load the rears rub the sidewall a bit. I have already rolled the front. Plan on doing the rear some day.

Fronts will probably rub the top of the wheelwells on big dips.

Okay thanks. Another question, my truck is a stepside so do I have extra room? And can anyone recommend front shocks? I've been told to use the summit sport shocks for the rear. I've also heard some talk about malibu or impala shocks once or twice.

I have the Summit sport truck shocks all around. SUM-G7722 is the part number for the front shocks.

The part number you gave must have changed but I think I got them. SUM-77013 for front. SUM-77018 and SUM-77002 for the rear. I think this is right? How come the rears are different part numbers? With this I have a djm 4/6 kit from spindles and coils and a flip kit. Static 90 how long have you had it lowered? The summit(doestech) shocks ride good? Thank you.

I lowered it Thanksgiving weekend last year. So I have been rolling lowered for one year now. Shocks ride great. I just checked Summit's site; look like they changed some part number up.

So for rolling the fenders it's just that one spot that the metal meets at and makes an edge? Or is there another edge I have to beat on?

[Static 90]

It is just the little lip right above the tire. I used my little grinder and cut little slits in it. Then I used a body hammer to bend it up flat. I removed the wheel first to have more room. I plan on doing the rear also, when the weather is a little better. I have to work in my driveway.

Yea working in the driveway sucks, especially when it's dirt.
