Rear Springs - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Ok, I want to buy some 6” rear springs for my 72 K5 but I am having trouble finding manufacturers that offer them. After calling each of the manufacturers, here is what I have found so far.

ProComp ----not offered
Superlift ----6 inch
Tuff Country ----6 inch
Rough Country ----not offered
Rancho ----not offered
Skyjacker ----5.5 inch plus add-a-leaf (EXPENSIVE!!!)
Fabtech ----not offered

Are there any other manufacturers that make a 6" lift 52” rear spring?

I want to get a set from Deaver Springs, but they dont show a listing for our year blazer but they have a listing for 6" springs for '74 blazer (not sure if it is the same length). I'm sure they could custom make a set if they don't currantly make it.

Also you might want to consider National Spring. They build a custom spring specifically for youre vehicle , but you will probably need to scale youre blazer.

That's what I thought you had said, but I called them directly today and they said no. Maybe they quit making them or something. They make a 6" lift for a 56" spring, has GQ been updated somewhere along the way?

Not that I know of

Rear springs are same for GM 4x4's from at least 71-87. As long as you have the 52" springs. Some 3/4 tons had 56" eye to eye springs. Measure eye to eye and order 73-87 lift springs with 52".

Musclerodz · 01-03-2007, 01:27 AM

Any 52" spring thru 87 should work. Or you could do a shackle flip kit to help retain ride quality.

I’ve heard that before, but I haven’t been able to confirm it. So why do the manufacturers offer a different kit for the 73-87 from the 69-72? Are the front springs different or what? My problem is I have to order all of this so I can’t just walk into a store and look at the parts. Thanks for the help.

I ordered a 4 " lift from rough country and was sent a 6" lift for my 71 4x4.So I know that they have a 6" lift that will work for a 69-72

I must have talked to the intern-in-training

or something when I called RoughCountry. All of the info that this guy gave me is different from what y’all are saying. I asked if they had 52” rear 6” springs for a 72 and he said no. I think he just looked through the application manual, didn’t see it right off, and gave up. 1969k10stepside, did they send you a 6” kit with rear springs or blocks? Maybe I need to call them again and see if I can talk to someone else. I’m not losing my mind. I even took notes over what the guy was telling me, didn’t get his name though, dang!

Angelse68cal · 01-08-2007, 02:19 PM

Ok The truth is you should really concider doing the Shackle Flip from ORD.

It Has a 4 inch drop so then you will only have to get a 2 inch spring.

The Shackle flip is so much better ride and also helps axel Wrap.

BADCHEV69, sent ya a PM!

I agree about the shackle flip having a better ride. I don’t like how it positions the axel farther forward and I don’t really feel like moving the shackle mounts around for longer springs to correct that. Maybe I will do it some day down the road.

Angelse68cal · 01-08-2007, 04:44 PM

Its not all that Bad I have it on my 72 Jimmy and I have a 8 in super lift. Its nice!

badchev69 · 01-07-2007, 03:05 PM

I had the tuff country 6's then switched to the skyjaker 8's...... huge difference in ride quaility. I was very surprised. I guess thats why skyjacker is so darn expensive!

1969k10stepside · 01-08-2007, 05:42 PM

I got the rear springs for it.I will post some pics later tonight of them.They are actually closer to 8" lift

1969k10stepside · 01-08-2007, 11:36 PM

Here are a few pics of the springs/truck.4" lift on front,about 8" on the back

.I have got ahold of the company I bought the lift from and they are going to get this figured out and get me the 4" lift I ordered....

Are you saying that they are 8 inches like they are right now on the bare frame? I'm sure that they will compress alot when the body is on. I believe that is how the manufacturers measure them.

1969k10stepside · 01-09-2007, 05:50 PM

It will go down some but there isnt much weight on the back of the truck so it might go down to 6" on the back
