    Do 52\" rear 6\" lift springs really measure 52\"?

    I bought some rear springs for my blazer and the guy said that they are 52" springs. Well I finally got to put them on last weekend and I had to stretch the springs out to put them on. when I put weight on the springs the shackle goes up hitting the tailpipe instead of going back. They measure 49" center of one eye to center of the other. Here are some pictures to help with your thoughts.

    I think you're ok. I've been researching rear springs lately and it appears that (on average) the unloaded eye to eye length is about 3~4" less than the advertised length.

    The stock position is up but it looks like you have custom hangers, right? It's hard to see in the pics but your custom hanger looks like it works similar to a flip kit. If that's the case I'd think your shackle would need to stay pointing down (probably like before).

    How much length difference is there between your old springs and these new ones?

    Yes the spring hangers are a custom shackle flip. I will measure the stockers that I took off.

    No... this is NOT ok...

    The lift springs you have are probably intended for a stock (un-flipped) shackle setup. With the heavy arch and no weight on them, they seem to be arguing w/ your spring mounting locations.... If you can't get them to compress to the point to where the shackle angle is acceptable, then you may not be able to use them... /forums/images/graemlins/confused.gif

    Actually.... from the looks of your pics... a 56" might just do ya!/forums/images/graemlins/thumb.gif

    What were you trying to accomplish w/ the new spring install? More lift?

    I'm guessing that a stock set of 56's may fix your shackle angle, but not lift you as much as you'd like.../forums/images/graemlins/dunno.gif

    ok well the springs that I took off measure 55" from end to end along the arc. so should 6" 56" spring fix my problem? /forums/images/graemlins/dunno.gif

    Re: Do 52\" rear 6\" lift springs really measure 52\"?

    I put 52" 2" lift springs in my blazer, along the arch they measured 52, across they measured 50"!! With the shackle flip done now, The shackle almost looks like yours!! Even if i put 300 lbs of weight on the tailgate, The shackle won't go straight!! /forums/images/graemlins/dunno.gif /forums/images/graemlins/dunno.gif /forums/images/graemlins/dunno.gifI am either going to move the rear shackle mounts foward or move the front hangers back. /forums/images/graemlins/hack.gif /forums/images/graemlins/hack.gif /forums/images/graemlins/grind.gif /forums/images/graemlins/weld.gif /forums/images/graemlins/weld.gifIf your stock springs measured 55", It sounds like you should have had 56" springs anyways!!

    That may be the problem. When the frame was built I was useing the springs I just took off. So I guess maybe he measured the spring when he set it up, so it is designed for a 56" insted of a 52". /forums/images/graemlins/dunno.gif

    Would the 2-4 inch difference apply to stock rear springs? I just got some today, and i measured from eye-to-eye, and they were 49 inches un loaded. The member i got them from said he took them out of a 2wd chevy truck. So are these really 52s b/c i thought they had to be 52 from eye-to-eye. Any help would be great. Thanks.
