here i am, i noticed that lot of people wondering how to get these sweet, beefy shackles on the truck, SUV.

i got the shackles yesterday, and i just go ahead install it today in the morning, after 4 hours of madshoot.gif i had it all done! i can't be any happier cuz the rear end is even to the front end now.

this is done on the 2002 blazer, i am pretty sure that it can be done a bit different way, espically with pick-up.

NOTE- spray oil on your bushing few time before you change shackles

NOTE- i found out that its not worth it trying to remove the exhaust and body parts tempopary, BUT if you think doing this will help, fine go ahead, good luck.

heres what you will need for a shackle install clicky clicky clicky ( you will need 13/16 and 7/8 inch socket and wrench)

this is the shackles i am installing

gotta find a nice, flat area to work on, hint- good idea to try to find a place to work on it, know that where it will be wont be in way in future if you failed to get the bolts out later- parked in garage

i have its rear tires on the ramp to bring the rear end up ramp

VERY IMPORTANT- Block the front tires to prevent from it falling off the jack stand
tire blocked

put your trustworthy jack stands on front spring eyes

i used the wood block to lift the rear end off the ramps

after the ramps removed, i get my jack under the U-bolts to bring the axle up to push the shackles back- which to clears the gas tank for bolt slide out- clicky

heres a bit tricky part, i just needed to use wrench to get the nut loose (leave the nut on to hammer on), then i use that big breaker socket to turn the bolt (not nut) several turns (keep turning till it get less effort to turn the bolt) to loose it up (it did the trick), then just start pounding it out. BUT if you want, you can just get the top bolts off first. then you can lower the shackle to clear the muffler and body parts to swing the hammer on it. clicky idea.gif

other way it can be done is to do idea.gif this, closer look, on the pass side to get past the exhaust and pounding the clamp like in the photo, it worked like a charm, but to make sure you is using a old clamp that you don't care to destroy like i did to this, and it isn't straight any more

this is a bit of PITA to get bolts out, and new in also on drivers side, just be patience another

after you removed the old shackle, you will go pretty fast put the new one on, then use all muscle you got to tighten it (impact socket gun is too big to fit in to use it) right side all done, but looks at how different from the stock side on left shakira.gif

all finished bobbytrendy.gif

oh man, this looks so ugly compare to this icon_lo.gif

BEFORE

SIDE

REAR

34 1/2 INCH from floor to top of the flares

AFTER

hope this help! drinkbuds.gif

I got this big dent from trying to pull a stuck ZR2 out of mud pit and I didn't see the tree behind me. Curse the tire and body design! Lol

Well, got mine on today and I have to say, it was pretty easy. I changed out both shackles in about 30 minutes. This doesn't include the time it took to put the truck on jack stands and trying to figure out why one of the bolts Chris sent with the shackles wouldn't thread right. I had to look at the bolt closely to notice that it wasn't threaded, it just had rings cut into it so the nut couldn't go on. I just used one of the factory bolts in it's place instead. All in all, I'm extremely pleased witht he results of the lift it gave my truck and would recommend it to anyone. I want to thank Brian, Justin and Jake LS1MikesTruck.gif for coming over and lending a hand with the install. I didn't take any pics, since I did the same thing as you did and your pics say it all. Thanks again for the tips Brett. icon_appl.gif

idunno.gif Quick question, and I only ask because I want to make sure I am not missing something obvious...but couldn't you skip the backing the car onto the ramps part? Just jack up under the rear pumpkin and slide stands under the front eye. Is it beacuse your stands were to tall and you needed what the block woud give you in lift??

you said that shackle was ugly, you should have seen mine on my 94 s10 (especially after I tried to pull a limb out of a tree with my truck and jumped the back of my truck 4 ft off the ground HAHA.gif )..(had to get a new hitch after that one) one side of shackle was completely rusted through and other side wasn't exactly immaculate either

i cant get it high enough to put the stand jack without having the tire to touch the floor when just using my jack, at least its my jack, could be different from yours.
