Square Body GM 2wd HD Front Spring Swap! 1/2 to 3/4 or 1 ton How Much Lift?

[@AmadOwns]

Very well explained, this was a good video man

[@thedriver02]

Thank you

[@rayjohnson7886]

I have a 1977 that I had the original 350 then went big block then went back small block. But I left the big block springs I think it was too much for the lower ball joints. The other day the lower ball joint popped out so I'm going back with small block springs.

[@thedriver02]

@rayjohnson7886 oh interesting, maybe they were worn out, and the stiffer springs did then in? My entire front needs to be gone through anyways so I be double checking everything, eventually.

[@rayjohnson7886]

@thedriver02 It's been a long time since I've installed them but Monday I found out one of the issues. The lower ball joints doesn't have grease fitting that's not good in the long run. The new ones I'll be able to grease hopefully things works out for you.

[@Milo30066]

Good job! I bought dulley front springs for my 1995 gmc vandura. I will try your method. Thanks

[@joesjunkgarage]

Thank you for taking the time to produce this video! Great source of information!

[@larrythomas3624]

How did you like that swap? How did the Caddy do? I have a 77 GMC 2wd 3/4 ton and a 500 Caddy that I want to put in it.

[@TAWS-wq3hx]

It will make a difference in 3/4 ton HD. My 80 suburban C20 (has C6P option) originally had a 454 in it. I swapped in a cadillac 472 (weighs 160 lbs lighter than bb chevy) and the front raised up 1 inch when it was all bolted down.

[@olivierfaucher3426]

Tighter shocks will firm up the ride, stiffer springs will carry more load and each will counter the other

[@olivierfaucher3426]

Stiffer springs by them self will only get the ride rougher and bouncy

[@PapaSmurf337]

I'm currently trying to figure out how the previous owner lifted the front end of my 2wd Blazer that I bought 17 years ago, as I'm thinking of replacing the springs with a fresh set. After seeing this, I'm thinking that he may have just used 3/4 ton springs not sure how to tell. 33's fit perfectly, the front fenders were also already cut. Everyone just sells drop spindles ... I think there used to be a lot more 2WD squarebody pre-runners back in the day but not so much anymore so now there isn't much of an aftermarket for them unless you get custom ordered sh!t which means $$$$.

[@efrencavazos8611]

I agree with you. How did the spring swap go for you?

[@illicit6266]

Great video, gave me some good info

[@sixtyfiveford]

Good info.

Lmk how it goes bro.

[@ADOTlied]

@@efrencavazos8611 I will

[@Geoduck.]

What size wheels and tires are those?

[@skullcrusher58]

So much easier if you just popped the ball joint loose imo instead of fighting with the u-bolts & trying to line everything up as you're going up & putting it under load

[@thedriver02]

@skullcrusher58 honestly it went pretty smooth gladly. And I didn't want to risk tearing up the boot, or damaging the ball joints, as they had all been replaced not to long ago. I didn't know about this spring upgrade back then, or I would have done it at the same time.

[@skullcrusher58]

@@thedriver02 that makes sense just how I would've done it but whatever is easier for you is works best for you.

[@marcuslimbaugh1326]

1991 2wd crew square. Help. How do I lift as much as possible

[@thedriver02]

You'll have to look online for the tallest rated coil. I believe there were some superlift I think was the brand of springs that would give a 2 or 3 inch lift. Rock auto is a good start. Also you could look into modifying the control arm or adding a spacer under the spring. Roughly a 3/8" spacer will net a 1" lift with the suspension geometry. Good luck

[@nestdiz6847]

I put one ton springs on my 1984 Chevy c20 it made a big difference with a 6.2 diesel on it. Does any one know if the spring spacers they sale on eBay or Amazon actually work??? they say it’s made for that year and weight but I don’t know

[@efrencavazos8611]

I'm curious to know as well. I've already purchased a set, haven't installed yet been busy with the LS swap.

[@redneck04jeep]

This really doesn't make any sense to me I put those exact same springs on mine and it raised it 3" and mine rides alot rougher

[@thedriver02]

What springs did you use? I would think they must be lift springs then. 3/4 and 1 ton trucks have 2 inch taller frame which is where most of the height comes from. All the springs I found were the same length, just slightly stiffer.

[@redneck04jeep]

@@thedriver02 used exact same ones as you did and when I was doing my research people was saying to use those to get at least 2" lift im just trying to look to see if possibly make it ride a little softer

[@efrencavazos8611]

If the coil springs did lift your truck a few inches then perhaps your shock absorbers new extended brackets or different ones...... maybe.

[@SLZR60]

You probably have lift springs, i recently bought a 3” lift kit for my c10 (took a while to find) and waiting for the weather to warm up so I can slap it on. It’ll be 3” in the front and 4” in the back with blocks so I’ll be getting 2” coil spacers for the front.

[@redneck04jeep]

@@SLZR60 I have the exact same springs as in the video everyone I know that has done it it lifted there trucks but he's only one that didn't and all of ours rode stiffer I mean mines so stiff probably feel a pebble which I'm about to fi that

[@kCI251]

Terrific video, thinking about doing the same on my 86.

[@thedriver02]

Ah good to hear, thanks

[@christianavelar7153]

What’s the biggest size tires you can run with this set up? Anyone know. Help would be greatly appreciated!

[@thedriver02]

31x10.5 clears with a good couple inches to spare. 32x11.5 should be fine. 33x12.5 will be close, but I plan to try with adding maybe 1" up front. I think then they would clear no problem

[@christianavelar7153]

thedriver02 will you be running that set up with the stock wheels? Or going aftermarket?

[@valenteherdon7396]

305/70R16 124/12R clears fine on my 87 3/4 ton 2wd chevy

[@thedriver02]

@@christianavelar7153 hey just saw your reply, if I do anything like going to 33x12.5 I would try with stock rims, unless I happened to find some tires on rims, then I would look into some adapters maybe. But it's all just a big maybe one day right now.

[@Josepht1993]

What size tires do you have after this? I have factory springs. Just curious what i can fit now and after this

[@thedriver02]

I have 31x10.5r15 on it currently before and after the taller springs. I think I could fit 33's, 33x12.50 is probably what I would try, but I won't be surprised if they do rub. Its about the height of a stock 4x4, 33's usually will fit but may rub slightly as well.

[@camarena572]

How many inches higher did the blazer go with the new spring thanks

[@camarena572]

Half inch just seen it

[@thedriver02]

Hi it was less than an inch after I drove it around they settled some it seems to be right around 1/2 to 3/4 of an inch. The springs themselves are the same height just the difference in spring rate gives a bit of extra lift plus the fact old springs probably sagged a bit over the years. Thanks for watching!

[@derekcraig3617]

i put 1 ton springs in my G20 van and it made the ride unbearably stiff

[@thedriver02]

That's too bad. love how it rides now, definitely not too stiff at all except in pot holes.

[@michaelkidd4408]

You did it ass backwards!! It's easier to knock the lower ball joint lose and drop the A arm that way. Instead of unclamping it from the frame.

[@brendabaldridge1284]

Do they make them for 1967 - 72 chevy 2wd

[@thedriver02]

I believe they do!

[@AMCguy]

I didn't know blazers were 2wd

[@thedriver02]

Most were 4x4, but 2wd was not uncommon. My dad also has a 79 2wd blazer stored away.

[@AMCguy]

@@thedriver02 is it lifted

[@thedriver02]

@@AMCguy only lift is from a 1" block in the rear, and the stiffer springs in the front but the height gain was minimal. It does have 31 inch tires which do make it sit higher than stock

[@DESERTHAWKIN]

How far off was alignment after this swap?

[@thedriver02]

Nothing noticable. Last I looked they were wearing a bit differently probably needed an alignment before hand anyways.

[@9thgatedim273]

Can u tow with a 2wd

[@thedriver02]

Sure can, 2wd is great for towing puts more weight on your drive wheels for more traction, plus no transfer case or front end parts to wear out.
