Lowering a 79 2wd Blazer - ?

I finally found a set of correct new rear leaf springs at a decent price. Once they're on I can put my wheel/tire combo on, lower it, and put new coil springs on front to level it out.

I'd originally guessed a 2/2 drop would put it where I want, based on how it sits now with sagging springs. The plan is to use 2" rear drop shackles. Will they bolt up to the Blazer without any cutting or other clearancing?

Re: Lowering a 79 2wd Blazer - ?

I dropped my 78 blazer a few weeks ago with drop shackles. There is a clearance problem with the filler neck on the passenger side when you put the shackle on. I could only use the 1" drop hole on the shackle after using a sawzall to cut off the 2" drop hole to clear the filler neck.

Re: Lowering a 79 2wd Blazer - ?

Ouch. I hope 1" is enough. I don't want to do any cutting on the truck. Thanks for the feedback.

What brand rear shackle did you use? I'd planned on using Summit's 2" rear shackle and 2" drop front springs. If their rear shackle has holes for a 1" drop they don't mention it.

Thanks again.

Re: Lowering a 79 2wd Blazer - ?

John, what leaf pack count does it have on it? I mean how many leaves make up the rear springs? You may be able to remove 1 leaf to gain that extra drop without severely softening the ride.
OR
Do a little shopping and you just might find some "lowered" replacement leaf springs in 2 or 3" or dropped spring hangers?

Jim, I wish you'd been in on my search for replacement rear springs. All the data is at work. I looked on all the websites I know of that make lowering kits - granted, that was only two or three since I've always lifted my trucks - but Google helped me find more. Rear leaf springs (OEM) for 73-87's are rare but pricey. I shopped around until I found a good deal. But I couldn't find any rear leaf springs for *lowering* the truck.

But that works out to my advantage. I'll get to mount the wheels/tires of my choice under new rear leaf springs. Then I'll know exactly how low I want to go to get it down where I want.

Re: Lowering a 79 2wd Blazer - ?

A flip kit will lower the rear about 4-5" and put it roughly level with the front end if the front has a 2 or 3" drop, as most 2wd's have a little bit of rake.


but if you dont want to go quite that ow, i guess the shackles will work

Here it is, the only pic I have now.



Seems to sit level. That's stock over 28" tires, which I plan to run, but wider. I just want to sit it down with something like a 1" gap over the rears. Thus the 2/2 plan.

Re: Lowering a 79 2wd Blazer - ?

I don't know John. I think a 3" rear and 4" front will put it just about right. Have you found any lowered leaf spring hangers? Not shackles but the hangers. Also there's the possibility of taking your new springs to a big truck spring shop and have them reverse the spring eyes to lower it or at the very least dearch them some. You can get a couple of inches out of that. That may be the best deal right there.

Have you checked tvblazer's thread? His is 2wd lowered. Leafs and air bags on the rear. You might find something there to help.

Re: Lowering a 79 2wd Blazer - ?

Boog, I posted that pic and regretted it immediately. It looks high in the rear there. If I'd posted a pic of it in my driveway, it'd look like an ass-dragger. On level ground, it is level.

The rear replacement springs are in the mail. I'll figure out what to do from there. I'm still convinced 2/2 will be perfect.

I just don't want to hack anything if I can help it.

Re: Lowering a 79 2wd Blazer - ?

Oh I understand your concerns. Blazers and Burbs are well known for sagged rear leafs after a few years. I have heard a company like Detroit Spring could make any spring you need. I bought some new leafs and coils for a 57 Chevy car from a local parts store that were made by TRW. Over 20 yrs ago.
Well hey, I'd keep on looking for springs, lowered springs, etc and if I found one I could return the stockers I had coming.

Re: Lowering a 79 2wd Blazer - ?

A cheap fix isn't easy. Flip the rear on stock leaf springs. If you swap out the rear hanger with one off of a 4x4 it will give you the frame clearance you need. The problem is you have to remove the gas tank. Grind the frame rivets off,... and then bolt on the 4x4 brackets. No gas tanks problems associated with using drop shackles.

Re: Lowering a 79 2wd Blazer - ?

bagged74,... The guy I sold it to lived in southern MO. This was a pretty cool ride,... but it needed quarters. I kinda wish I would have kept it and put a later model tub on it. '89-'91 4x4 blazers are pretty cheap around here. Do you have any pics of your buddys? I'd know it if I saw it.

Re: Lowering a 79 2wd Blazer - ?

Blazin79,... Don't be surprised if you don't get a full two inches. New springs usually means they are going to raise it up. Add a 2" shackle and you might be right back to where you are now. I guess I don't understand what you are trying to achieve. Are you going to pull a trailer? Is that why you want to change the springs? Why not just add the shackles to your "sagging" springs?

Re: Lowering a 79 2wd Blazer - ?

Yeah, I know... I've got a bunch of spring sag. If 2" drop shackles get me back where it is now after putting replacement rear springs on I'll be in good shape. It's not like I have any choice, the springs on the truck are shot. I've never seen it at factory height, but I'm pretty sure 1" or 2" will put it where I want.

Again, I appreciate the help.

Too many distractions the past few months, but thankfully I have time to start in on the Blazer again. It hasn't been driven in months.

The new rear springs are a 'must have' - I don't know yet if I'll run a small block or big block but goals are at least 400 on the motor + spray. I can't have weak springs doing some axle-wrap and breaking things. I decided to get the rear springs installed instead of doing it myself when the mechanic I use said he'd do it for $100. So I'll drop it off Monday or Tuesday. I'm terrified about going to pick it up and it looking jacked up in the rear. But whatever, I'll deal with it.

The 15x10 rallys came in grey primer so I need to paint those and get some tires on. Then I can decide how low it needs to go to get the look I want.

I wish I could paint the wheels this weekend but it's supposed to storm all weekend. But I'll get some pics up with just the new rear springs on when I pick it up. Wheels and tires will be on soon enough. I'm just glad to be back on the project.

Re: Lowering a 79 2wd Blazer - ?

Give these guys a call:

http://www.huskyspring.com/Default.taf

The direct replacement springs are pretty steep but the sales guy was great, we went through all the options for the truck and there was a set of pickup springs with nearly identical specs that were less than half the cost of the direct replacement springs.

I have the specs of all the options for the truck at work. I'll bring them home tomorrow and post them.

Nice screen name.

Re: Lowering a 79 2wd Blazer - ?

Cool thanks Bro, ya I just registerd last month
but today was the first time I posted and saw your user name
it was bizzare that I was just one letter off yours!
I picked up a nice black 2wd 79' from up state NY from the original owner
70k miles never driven in winter and hasn't been on the road since 99'
rustiest part on the truck was the battery tray! I'll have to get some pics
now and as the work progresses over the next few months.
Its gonna look kick-ass next to my 97' 2dr 2wd GMC Yukon.
