    the rear springs on my 90 are sagging bad, and i want to chuck the lift blocks(4"). a while ago i seen a set up for a shackle flip using the front spring hanger from the rear of a chev truck.can anyone give me more info on this set up? is it worth the effort(i dont wheel as often as i should) what kind of a ride can i expect? thx, oh yea i'm gonna buy some new .

    so many parts, never enough money

    Blue_Beast (AKA Jason hughes) did this to the rear of his Blazer. I had a chance to look at it and I was impressed! It looked factory! Send him a private message or something...I'm sure he'd be happy to answer your questions for you[​IMG]

    I did the same thing to mine. It was very easy to do. The ride didnt change noticeably, but the fact that the rear blocks are gone is a big improvement. I dont have any good pics of mine, but as Rene said, Blue_Beast has some good ones.

    i CUT THE BOTTOMS OUT OF MY SHACKLE HANGERS (oops) but I think eventually I will swap to the front hanger in the rear set up instead. It's a little beefier and doesn't look too complicated.

    That jeep thing? Yah I understand it....... Like my Blazer? <a target="_blank" href=http://community.webshots.com/user/blazerk5>http://community.webshots.com/user/blazerk5</a>

    I personally think that what jimmyjack did is suicide. I might catch flak from that, but I would not do it. Bad idea in my opinion.

    A front spring hanger from the rear of a 2wd and a lowering shackle for a 2wd truck from JC Whitney works real well and costs about $50.

    You have to find a pickup frame... then you cut off the rear leaf spring front hanger rivets and remove the hangers. Cut your stock Blazer rear leaf spring rear hangers off and bolt the pickup one on. Its a piece of cake to do, although you will prob have to remove your gas tank to do it.
    I can try to scrape up some pics of it, but no promises...

    No flak from me bro! I've had no problems with it what so ever tho. But it doesn't mean the next guy won't. The guy that threw me the idea runs 35" tires and tows a trailer full of quads with his and it's almost been 5 years since he did his. I agree there's not a whole lot of meat when the cutting is done and I get a little nervous out in the boonies when i'm wrapping the axles up, but I get home every time. Like I said tho, for my piece of mind I will eventually go with the other set up. Just a bone for you guys installing the "new" shackle hangers..... instead of removing the gas tank, tie a piece of fishing line to the bolt and pull it thru the frame. This is how I installed my receiver hitch. It makes it a breeze!

    Hey Blue_Beast, that's exactly what I'd like to do to mine. Does that hanger fit the stock holes in the frame or did you have to drill new ones? Also what kind of truck did you get the hanger from? How many inches of lift did you get? Did you have to extend driveline or lower the T-case?

    Thanks.

  11. you have to drill new holes and cut the bracket down. i got it off an 81 4wd shortbed. got 4 inches and had to shim the pinion back down. best thing to do when looking for a spring hanger is take lots of measurements so you know it's going to work. 4wd 1/2 and 3/4 ton trucks seems to be the hot ticket for these brackets. the spring eye should be 4 inches below the the bottom of the frame and the hanger should place the spring outboard of the frame the same distance as the ones on your blazer. happy grinding![​IMG]

    Blue Beast,

    Does this kind of shackle flip push the front axle forward a little like ORD flip brackets? Or does it keep the axle in the same position as the stock set-up?

    In the process of doing mine now.[​IMG] I am cutting the bottom of the hanger and will be welding in some bracing to the top.

  15. well, yes and no. the only thing that will really move the axle forward is one of those blocks with offset centering pins. technically though, as the spring moves down it moves in a arc and therefore does move forward. i could not tell a difference though. i have 4 inches lift and 35s and have to tire interfierence at all. i did cheet my brackets forward 3/4 inch to keep my shackle angle where i wanted it.

    it's amazing how much interest shackle flips get. i think they are a great way to lift the rear. the methode i used is cheep but requires more labor (grinding off 2 sets of brackets instead of one) i think i have just as strong of a set up as the ORD. i'm not knocking them and would gladly use there stuff. this is just a cheeper rout. if you don't want to fuss with more grinding and measuring than go with the ORD. so i guess what i'm saying is, well, i'm cheep and like to do more work than i have to.
