Shorter rear shocks for lowering springs?

I was wondering if anyone has found a decent rear shock that would limit the droop travel of the rear axle with 3" drop springs? I'm planning to install 3" drop springs from CPP on my 67 chevelle SS. I've searched the net for extended length of available shocks and couldn't find any info. Otherwise I'll just have to bolt down the lower pigtails with some large washers.

I've seen KYB shocks in the OPGI catolog for extremely low applications. Here's the link to their web page http://www.opgi.com/product.asp?topc...0167&yearrange=

Re: Shorter rear shocks for lowering springs?

Just to follow up - I received my "low profile" KYB shocks from OPGI. Same length as what came off the car, same length as the KYB's I picked up at Advance.
I also installed my 3" drop springs from CPP: More like 5" drop springs which was exactly what I calculated when I received the springs and had an idea they were too short. Pinned the jack body between the gas tank and the floor.
The tech guy at CPP was helpful though - I had him pull a set of 2" drop springs, and make some measurements so I could calculate the drop I would get with them - That math worked out to be about a 4" drop.
They'll both be sent back. The moral of my story is - Spend the extra money to order from a shop that actually knows what they sell. If there are no specs listed for specific parts, then be leary as to what you will be receiving.

Re: Shorter rear shocks for lowering springs?

off subject..... but I'm still waiting for the ball joints I was told would be pre-installed in the upper and lower control arms from CPP. I mean its only been 1 1/2 yrs since they were gonna send 'em out right away!! I personally won't buy from them again.

Re: Shorter rear shocks for lowering springs?

A note on lowering.

I just ordered springs from Mark at SC&C. I was planning on dropping the car 2-3" around.

He said, "nope, can't do that. There's only 3" of total rear axle travel in your '70". "Most of the "A" bodies will tolerate a 2"-3" total ft. drop and the rear, well, anything over an inch and you'll be slamming into the bump stop on every ride." "My recommendation is 2" drop front and 1" rear."

He has a world of experience and will help you if you call.

I think the 80's G-body has a very similar shock that is a little shorter and they do bolt up on the top and can be made to fit the bottom using a new bolt.

Re: Shorter rear shocks for lowering springs?

Hi all I have scanned and read many forums etc to get some advice but no detail apart from buying a kit from a aftermarket supplier. I wanted to get off the shelf parts so I did the Research for My 66 El Camino.
I dropped it 2" in the Rear and found I needed a Shock extended lenght of approx 20.0" and Compresed Lenght of 12.5" Approx. what I found was.

Original 1965-67 Chevelle / El Camino uses 21.89" Ext - 13.54" Comp p/n KYB KG5507
Buick Regal 1983 uses 20.83" Ext - 12.95" Comp p/n KYB KG5548
Chevy Nova 1969 Mono leaf uses 20.04" Ext - 12.56" Comp p/n KYB KG5504

So I have ordered some KYB Gas Adjust Shocks KG5504.
I hope this helps you guys as it took me a few hours to come up with these numbers.
