How low? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Blazer383 · 01-23-2013, 06:40 PM

I'm going to order my lowering parts soon and I was wondering how low can you go front and back on 20" rims without C-notching the frame? I would like the 71 Blazer to sit level. I was thinking of on of these two, a 3-5 drop and a 2-4 drop. If you have any pictures that would be a big help too.

Look for "stance photos.
First is stock.
Then 2.5/4
Then 3.5/6

Personally I would go 4.5/6.

So how do you achieve the 3.5/6? Spindles (2 1/2) and - - -

My old 5/6 static drop,...

Sandemonium · 02-01-2013, 02:22 PM

I have a CPP 3/5 drop on my '72 2wd Jimmy.

With the top on and the carpet and back seat out it sits a little high in the rear. Once I put the back seat and carpet in it should sit level. However, once I remove the top then it will again not sit level.

I had to put a c-notch in because the clearance between the axle tube and frame was too close and would have made contact while driving.

At some point I will be replacing the 5" rear springs with 6" springs.

Good luck,

Bob

Just got off the phone with ECE and they said you can do a 4/6 drop without c-notch. Does that sound right? Wouldn't the axle hit the frame with every little bump?

Next question, what is the easiest c-notch? The porterbuilt bolt in notch looks easy, but you have to take off the body.

Thanks,
Matt

What size tires did you have on those 15's? I like the look.

**lolife99** · 02-08-2013, 09:08 PM

You can do a 6" rear drop on a truck without a c-notch.
The blazer would need it.
I know that from my own 71 2wd blazer.

YBNORML · 02-09-2013, 04:14 AM

I agree with lolife, my Blazer has a 5/7 drop. 2" spindles, 3" coils in the front, 6" coils and 1" block in the rear. Before I added the 1" block I had to put in a c-notch because it was too close for comfort.

Nice blazer! I was wondering how your blazer drives with that much static drop ? Any issues ?

BigCountryx · 02-19-2013, 08:53 AM

Can't speak for YBNORMAL but my blazer drives better now than before the drop.

Thanks for the compliment. I personally think the ride is fantastic.

I would get the air bag kit from ECE for the rear if you can afford it. This will elimenate all the issuses of ride height differences due to top/seat/payload. Thats what I did, and I liked the ride so well that I put airbags on the front when I did my frame off. Oh, btw, I didnt notch my frame, because I never really had any problem with it before I quit driving it for the restoration process.

5.5"/7" with a cpp bolt in notch

Did you have to remove the body to put in that bolt in notch?

Great looking Blazer.

BigCountryx · 02-11-2013, 07:20 AM

No need to remove the body for the cpp notch. It bolts from the sides and the bottom. Also the setup is McGaughy's 2.5" spindles and GMC Paul's 3" springs up front. GMC Paul's 5" springs and some 2" blocks out back. I used a McGaughy's adjustable panhard bar in the stock location (PB's panhard will not fit with the CPP notch by the way) and No Limit's shock relocator kit.
