Heavy Duty rear lowering coils...
I`ve had my 67 Suburban since 1998, I lowered it with all ECE parts. It has 5" drop rear springs (with an air lift bag inside it) and about 1/2" blocks in it now.
I`m happy with the look but it`s gotten so bouncy, with or without adding air. I`ve swapped out shocks as well. I was thinking about trying "Classic Performance Lowering Coil Springs RCS603-4HD" Any body have any opinion or other options? Thanks!!! https://www.summitracing.com/parts/c...ckup/year/1967

Re: Heavy Duty rear lowering coils...
I have these springs in the rear of my C10. I've also had the ECE 5" rear springs in the past. To me, these 4" HD springs are far superior to the 5" springs. My truck was also bouncy with the 5" springs, and forget putting anything in the bed. The 4" HD springs feel much more balanced and pair well with the 3" springs I have on front. I've also loaded up the bed with about 600 lbs of scrap metal before and the springs handled the load admirably. I was hesitant to add more weight at first, but after driving it I know it could handle more. Granted, this is all for my shortbed, so I'm not exactly sure how they'd feel in a Suburban.

Re: Heavy Duty rear lowering coils...
I have the heavy duty 4 inch drop springs on my panel (not road worthy) but I wanted at least a 6 inch drop. So I put two inch blocks on it. The problem is Im running 15 inch wheels and with the two inch blocks you end up with a scrub line situation.
