January 20, 2007Has anyone installed a 6" all spring lift on the rear of a k1500? I removed the blocks/stock springs and replaced them with the superlift 01-364 springs on my 1995 suburban and they are hitting the shackle hanger. Has anyone else ran into this problem with the reverse type shackles on the rear of 88-98 chevys? I'm not sure how to remedy the problem yet, but I will post as soon as I find out what went wrong.

January 21, 2007Suburbans and tahoes use 30" long springs, where the pickups use 32" long springs. The spring you are using is too long so it is pushing your shackle back into the frame.
January 21, 2007My springs measure like 58" eye to eye and the new ones measure 60". I believe that's exactly the problem I'm having. Thanks
January 21, 2007Tahoe's are able to use lift springs for a '73 - '91 K5 Blazer, but I'm not sure about the Suburban's. I'll have to measure one tomorrow.
January 21, 2007Your springs measure 58 with them off the truck eye to eye?
January 21, 2007Yes. I have one off right now. The stock spring measures 58" center of eye to center of eye. The new springs measure almost 60" eye to eye. I think they must have sold me the wrong springs. I will know tomorrow when I contact the manufacturer.
January 21, 2007My '97 Tahoe was similar(measured 54"), but I could get away with using 52" '73 - '91 K5 rear lift springs.
'88 - up pickups use 63" eye-eye springs(with weight on them), while your Suburban uses 60" eye-eye springs(with weight on them). You weren't sold the wrong parts, you unknowingly ordered something that won't work for your vehicle.
If you want 6" lift springs for your '95 Suburban, they'll have to be custom made.
January 22, 2007chevy used a 56 inch eye to ey spring which would be shorter than what you had but also short enough not to hit like the 60 is going to or at least I believe you mentioned it. Anyway you are stuck a little to long or a little to short it is your choice. The 56 were for the 69-87 chevy also and they would be a little closer the only thing is I am not sure of the center pin location
January 22, 2007Yeah I got the answer today from the shop that sold me the wrong springs. They just read the superlift manual and sold them to me without knowing the difference. You are both right. The springs are measured differently then I had expected also. Apparently they measure along the curve from center pin out. The springs they sold me are definately for the pickup and measure like 32" from center to eye forward and backward. The springs my suburban needs measure 30" from center to front and back eye. I checked into the 56" springs as well and they have the center pin set at 26" to front eye and 30" to rear eye. I spoke with Spectrac suspension today and they are going to make me a set of springs for my application.
I think it's very odd that none of the lift kit manufacturers make the springs I need. I suppose 95% of the people that lift their subs are happy with blocks
Thank you all so much for all your help. This Forum rocks! I'll keep you posted on the progress and post some pics of my rig asap.
January 25, 2007If you have any trouble with those new springs I have used a company a lot they do great work and I can get you their number. If the new ones don't work for you.
January 25, 2007Well I've talked to pretty much everyone in town and my only options are to either have my springs re-arched with an add a leaf for a total of 2 inches of lift. I would still need a block for total lift. My other option is to have a set custom made and they want to charge me $800-$900 for a set of custom 6" lift springs which is ridiculous. lol
