5.5 7 drop with 235/75/15
I've looked thru the drop posts but can't see any or missed them. I'm currently at a 3 5 drop. Can I do a 5.5 7 drop without any issues with my tire wheel set up? Exhaust or tie rod? Anyone have any photos and with white walls if possibile?

Re: 5.5 7 drop with 235/75/15
I wouldn't go more than 4.5" in the front. Crossmember gets REALLY close to the ground and the 3" springs cause issues with being able to get alignment in spec.
7" should be fine in the back with shock relocation. I have a leaf flip on the rear of my '69 that netted just over that amount using the DJM kit. My front is 4.5" with ECE disc spindles and 2" springs.

Lowering blocks are lowering blocks, just make sure U bolts are of decent grade, and you really can't go wrong. $32 seems like a hell of a deal.

Re: 5.5 7 drop with 235/75/15
7 inch in back , you need a c-noch in the frame
5 in front , im sure 2 will have to come from lowering spindles , tire size and maybe other front end issues will come into play , lots of experiance on this board , someone who has done it will chime in , mine 3 5 , no issues , Ive herd of others doing 4 6 with no issues , but 5 7 , I know you need a c-notch minimum

Those are leaf spring lowering blocks. You need trailing arm lowering blocks. http://67-72chevytrucks.com/vboard/s...d.php?t=454824

The leaf spring style has 4 unbolts and no holes. The trailing arm style has 2 much larger u-bolts and holes in the blocks that match the hole spacing on your truck rearend and shock plates. You won't find these at your local auto parts store. These are specific to 60-72 trailing arm trucks.
