I need 15" or longer spring bolts to get the wheel into the center of the wheelwell. Either the spring is a pile of crap and has too much lbs/in or the spacer is supposed to go on the bottom of the spring? Looks like i will be going back to the old stock steel spring i took out. Anybody want to buy this one?
What's the spring rate? Looks like it's installed correct. The aluminum block may have to go under the spring. Depends on rate. How do you figure 15" spring bolts to center a wheel? Spring is out of the GM mold and made by Hyperco. Not a pile of crap.

So the spring comes in a box with no spacer and no instructions? i have to call to get the spacer and still no instructions? does the spacer go where i have it or below? pretty simple question, the guy from Hyperco couldnt answer it either.
Looks like this is the stiffest spring they make, its a 200 lb / in and the spacer can go to the bottom to lower the car. Will try that and see what it gives me for height. Would be nice if the vendors selling this stuff informed you of the available spring rates and which is correct for you car and application.

Mr.Grumpy- I just installed a spring from VBP it is a 330 lb spring., there was a block (not aluminum, but composite?) attached to the TOP side of the spring, just as your aluminum block is shown. From the pics, it looks like you need to pull up on the bolt nuts at the spring ends. Mine have 1 1/8 inch threads showing from nut top to end of bolt- hope that helps.
Glad to see you're back at it, i was missin your post and pics. now me can dream some some!
It's was more cost effective to do an aluminum block so thats why the spring comes that way. You have to have some type of spacer or else the spring plate would hit the cover bolts (cast iron diff) and you would have to go with short bolts as well. VBP & Muskegon's TRW springs both have spacers. They chose to divide their spacers top and bottom. No matter what, the thickness needs to be the same as a steel spring or close to it so they do not hit the cover bolts. If it wasn't as thick, a lot of you would be pretty pissed b/c you ran the 2 forward bolts up to far and cracked your rear end cover.
These are high arch springs so that is the reason for the low spring rate. As I mentioned, these are out of the GM molds and this is the same rate that the 81, 82's had. Care to guess what a 9 leaf is rated at?
Hyperco makes a 200, 330 & 360 # spring. I only sell the 200 and 330# springs to customers. Some vendors insist they have to have 360# springs so we supply them with the 360's. It's to hard to get ride height with the 360 spring.
You guys have the option of spring rate for your application. On a BB car, I wouldn't go with the EZ Ride Spring, I would go with the 330#.
Grumpy,
Try moving the car or bouncing the rear a little and it should come down a bit. Don't tighten the spring bolt nuts as mentioned if you want the car lower in the back. Longer bolts lower the rear so tightening them up will not help.
I have 8" bolts in there now, and there is about an inch of thread sticking out the bottom of the nut. I tried bouncing the car, its pretty firm lol.I am sure as i drive it it will come down. I am ok with the way it sits. I also got the sway bar connected, way easier to do when the car is sitting on the floor. I tried the 6" factory style bolts, but they were going to be too short with this spring.
Vansteel will that spring soften over time, or will it remain the same?
It shouldn't settle but once you put the car in reverse to back out the back end should drop and thats pretty much where your ride height is going to stay. What shocks are your running?
Hey grumpy, here is a shot of mine when I did my rebuild, although your rearend puts mine to shame. Looks like you can eat off of it.
Not sure what year they moved away from the steel springs on the 80's. I thought most had switched to the composite by then. Or maybe the 4 speeds had steel springs. Here is a pic of my stock spring, my space looks a bit different than yours, yours is obviously new and better design. I got 8 inch spring bolts and I got about a 2 finger width gap between the tire and the fender lip. I have them as low as they will go. I would like another good inch lower, so I will probably have to go with 10 inch bolts and cut the remaining amount down. As mentioned above if you roll that car back about 30 ft or so, the IRS should settle.
