View Full Version : Block Lift Question
10-03-2006, 09:55 PM
I bought a used 4 in block lift for my Blazer and have since learned that block lifts have their disadvantages. So i'm wondering 1. what I would have to do to change that? The blocks are only in the back so would I just have to put on bigger leaf springs in the back or is there other stuff I would have to do and 2. is it even necessary? I'm only using the truck pretty much for church so will blocks in the back really be that big of a problem? Let me know what you think. Thanks

blocks are fine just make sure your u bolts are extremely tight and stay that way. you dan do a shackle reversal to get some more lift out of it. having no blocks is better than having them but sometimes you just have to deal with what you got. i ran 5.5 inch blocks in the back of mine for a while without issues until i got lift 6 inch springs and i still have 3 inch blocks and 3 inch shackles.

Best mod if not already done is to go to the wrecker and get the front mounts for the rear springs and use these mounts to replace the rear shackle hangers and it will allow you to "flip" the shackles on your rear springs so now the spring hangs below the shackle instead of above the shackle and gives you more lift and better ride out of the same springs. The only thing you have to watch is your rear axle angle for the rear driveshaft you will have to either use the small angle shims to get the angle back to where it was or cut the spring pads off and turn them and reweld them on.
And if you look around some of the different models of chevs , ie 1/2 ton 2 wd or 1 ton 4wd , have different hieghts of this spring mount so you can get different amounts of lift.

If you want to go the fabbed route, sky, diy4x4 and ORD all make shackle flips. They basically look lik these:
and diy4x4: these ones are reverisble so you can run 52's or switch em around and run 56's!!!
thers more too.
basically, you can scrounge around in a parking lot or make some like Rene from here ( http://www.funinbc.com/forum/showthread.php?t=70613 ) .
I really like the di4x4 kits, they are mounted really nicely with backing plates for more support, look to be pretty beefy, reversable, etc. You will have to drill out your current holes to 9/16 i do beleive. They run around 185 if i remember correctly. The way i fugre it, 50 or so bucks from a junkyard to scrounge or have some really bling bolt on shackles that are beef and look good too. You choice, i also do beleive you will have to lower you fuel tank to access the inner frame rail to tighten down the nuts. CHeers

Depends on how much of a budget he has. If you're gonna run the piss out of it, i'd build some like Rene did. They dont gotta be pretty, but they gotta work. You can run the hangers, seen em on the front of 2wd chevy's with the 64's i know for sure.

Whatd you decide on? If it helps, i am not 100% sure but i am fairly certain that those hangers are from the front of the rear springsin the 88+ trucks.

I think i'm just going to put the blocks in and make sure the u-bolts are really tight. The truck is pretty much just for the odd Sunday so I don't want to put a lot of time and money into it. Like jakerngr said "sometimes you just have to work with what you got".

man, i love those vise grips!!!
you gain more then just a bit of hieght with a shackle flip
ride quality improves a lot when you get the shackle angle where it likes to be
