Re: 69 camaro rear shock diffrence between mono or multi leaf

in 67 they had mono springs which is straight shocks. in 68 they went to staggered mounts shocks for better traction or less wheel hop.also to multi leaf springs.

Re: 69 camaro rear shock diffrence between mono or multi leaf

The main difference in the shock is the configuration of the lower mount.

The mono leaf spring plates "sandwich" the shock, metal on both sides, and the shock is attached with a through bolt.

Multi plates only have one much thicker ear, not a sandwich. The shocks hardware kit contains a kinda big stud thing, which passes thru the shock plate bracket and is nutted, and the other end passes thru the shock and is also nutted.

I'm not sure if the lower shock mounting grommet is different, I think the one for multi's will have a larger OD.
Some have said the shocks are different lengths, multi's slightly longer,I've never checked that.

Re: 69 camaro rear shock diffrence between mono or multi leaf

Jim is correct. Shocks for a multi are slightly longer, and have a larger ID rubber bushing to go over the mounting stud/bolt.

Re: 69 camaro rear shock diffrence between mono or multi leaf

does anyone have a picture of the multileaf shock set up?
I am concerned that the bilstein shocks I have for my 68 may not be for a monoleaf setup.

Re: 69 camaro rear shock diffrence between mono or multi leaf

Multi leaf shocks have a stud built into the bottom mount of the shock. Mono have a hole for a bolt... Well at least Koni's do...

Re: 69 camaro rear shock diffrence between mono or multi leaf

My camaro had mono leaf and was converted from mono to multi leaf but the bracket the shock connects to is from the mono leaf set up. The shocks connect off set and are bolted in between the bracket. For Future refranca should I keep using mono shocks or could I use multi leaf shock with this mono bracket? Would it be better to convert to a multi leaf bracket so I can use the correct lenth/bolt style shock for the multi leaf springs I am using on the car? thanks for the help

Re: 69 camaro rear shock diffrence between mono or multi leaf

Mono shocks bottom hole should be 3/8" dia if I remember right.. Multi stud hole more like 1/2" or 9/16".....

I had H-D, multi Monroes on my car and I just took a piece of tubing and notched it and shimmed the holes down years and years ago..

Re: 69 camaro rear shock diffrence between mono or multi leaf

were you able to use the emergency brake retainer bracket that the mono bracket has with the multi leaf springs?

Re: 69 camaro rear shock diffrence between mono or multi leaf

My shock and spring perch info:
http://www.pozziracing.com/rear_susp...r%20Shocks
You can convert a mono leaf shock to multi leaf by adding the stud to the lower shock eye, but you need a Multi-Leaf spring plate. Shock lengths are the same, but plates have different heights for the shock mount, mono leaf plates mount the shock lower because the mono spring is thinner.

One thing you can't do is add multi leafs then use the mono leaf lower plate. The plate is moved downward by the thicker spring pack and the shock is not long enough to reach. This is why people think mono leaf shocks are shorter. You can add a drag race screw on shock extender to the top of the shock to make the mono plate work. This is a pretty common fix.

Another problem is on 67 Camaros, the 68 plates won't fit.

Re: 69 camaro rear shock diffrence between mono or multi leaf

My car is using multi leaf springs with mono shocks and shock bracket plate. So this will need to be changed to multi leaf shock bracket to fik the problem, I have the monro rear multi leaf shocks that the guy that installed the multi leaf springs did not use he told me that the gabrial shocks were still good. Looks like he was full of it and could not get the multi shocks to work with the mono bracket? thanks Steve

Re: 69 camaro rear shock diffrence between mono or multi leaf

Also when I change the shock plate should I mount & torque the new plate to the axel before the axel is under the car or leave it loose till the leaf springs are loose mounted to the front bracket and shackle than torque it all together? thanks Steve

Re: 69 camaro rear shock diffrence between mono or multi leaf

The '69 mono plates should be studded so are fine!!

It's only the '67's that give us a problem b/c their plates are mirror's of each other so we can't rotate one plate and use it on both sides!!! Like your hands if you look close...........

They are left and right so two plates are used whereas the '68/'69 rotate one plate due to the front and rear staggered shock locations..

Now, changing questions here!!

Don't tighten anything down UNTIL it is on the ground and you have bounced her up and down several times!!

Re: 69 camaro rear shock diffrence between mono or multi leaf

The mono plates that I have on my 69 are not studded they have the staggered shock mount but uses the metal bars that the shick base fits in between. Is thereaway to put a stud on this type? I was told that the mount area was to low due to the added leafs in the new springs? thanks Steve
