Dropped...now wheel interference! - The 1947 - Present Chevrolet & GMC Truck Message Board Network

We just dropped our '77 C10 with DJM 3-inch spindles and 2 inch springs in front. The old Krager 15 inch wheels have some slight (bout 1/16 inch) interference with the spindles. Will 16 inch wheels fit or will I have to go with 17's? Anyone have to deal with this problem?

Are they scraping on the A arms? I heard that you have to grind off some of the A-arm lip to eliminate the scraping on 15" wheels. This however is not the case if you have 16" or 17" wheels.

The portion of the casting that holds the disk brake calipers is scraping on the inside of the wheel. I have not turned it side to side to the locks to see if it interferes with the "A" arms yet. One thing at a time...LOL! It is just the top outer portion of the casting too.

I think also mentioned in previous posts about this is grinding off some of the spindle surface which I think may be in DJM's instruction sheet that came with the drop spindles. You might call DJM's customer service.

I tried DJM and they are closed today...LOL! It looks like I can grind off that section of casting...I only need about 1/16" and it is not a highly stressed section anyway. I was just hoping someone had done this. I will check their on-line installation instructions. There were none in the box! Thanks for reminding me about that.

16s will work but prefer 17s for better clearance and apearanc
