67 Camaro mono to multi leaf

[DButler]

I have a 67 camaro and I am possibly looking to switch my car from mono to multi leaf. I put stock replacement eaton mono leaf on the car when I restored it. Couple questions as to whether or not I will benefit doing this. Also i am about to put qa1 star stockers on the car all around. I know my car doesn't have staggered shocks like 68 and 69 so will all my factory brakcets work or will I need new ones? If so then where would I find these since not many 67s had mutli leafs and I know 68 and 69 is not interchangeable due to the shock placement. Any help is greatly appreciated. Thanks And also what rates springs will I need. I have hotchkis in front. Any brands recommended? I am also w=running 2 inch lowering blocks right now.

Take a look at the Hotchkis springs. I have run these on several cars and love the performance.

I know there are lots of springs out there. Don't know if these are the absolute best but from my experience they are great. I also ran the fronts and thougt they worked well together.

shock plates would be the same, you need multi leaf perches on the rear end.

[DButler]

Why would shock lengths be different....I understand that multi leaf is thicker but what if you are using a lowering block would it equal it out? Say a multi leaf and a mono with block how would that compare for the shock?

check with Hotchkis. I think their lower springs are designed to work with mono leaf perches.

Shock plates are not all the same! 67 did not have staggered shocks and have there own shock plates. 67 camaros all had mono leaf springs. Keep your stock shock plates and use this kit from DSE. You could run there springs as well.....

x2, just did this swap on my '67. Mono leaf perches work with the Hotchkis multi-leaf springs.

Dave,

Not sure if you are looking for multi's for a specific reason, but here is an option possibly:

Not sure if it is common but we replaced a set of these after they started to spider web crack after 2 years on a weekend warrior. They were the Vette Brakes product exactly what is in the link. This was on a 67 with a very mild 350/350 and 10 bolt mono application.

A good friend of mine had the exact same thing from vette brakes and his broke into going down the road and nearly messed his car up....vettep brakes or suspension whatever it is called wouldn't do anything about it

I just installed qa1 star stockers on the rear of my car and have them for the front just have to install. I have them set at the lowest adjustment now. How many clicks should I change them for decent ride and good handling? Also it seems like my passenger side sits a little higher now than the driver side. maybe it is like that because it hasn't settled any after being put down on lift. Anyone have any ideas as to why?

[David Pozzi]

It is not a good idea to use mono leaf shock plates with a multi leaf spring AND lowering blocks. The 2" drop Hotchkis leafs generally require a 1" lowering block. The 3" drop don't need any.
Mono leaf shock plates locate the shock eye lower than the Multi-Leaf plates. This reduces droop travel if you add lowering blocks, and the rear shocks might top out under hard braking which could be very unstable. Lowering springs with no blocks would be OK. The Multi-Leaf shock plates are thicker and resist bending, unlike the mono-spring plates.

Right now on the rear I am running eaton mono leafs with all mono leaf spring plate. I am running a 2" lowering block with qa1 star stocker shocks. I am possibly looking to switch over to multi leaf in the future if the benefit is worth it. I bought the set of shocks from a forum memeber and he didn't specify whether or not they were for multi or mono leaf springs. I compared the shock to my cheap original shock and the two where the same length. What would be the advantage of going to multi leaf over mono?

[MyFriendScott]

I installed Hotchkis 1.5" drop multi-leafs in my '67 when I swapped in a 12-bolt with multi-leaf spring plates. The mono-leaf spring plates on your axle are too shallow for a multi-leaf and a lowering block. The 1.5" lowered spring in the rear, in my opinion, is about 1" too high for what most people are going for. So you'll probably end up wanting to run lowering blocks still even after installing new multi-leafs. I ended up installing a 3/4" block a few weeks later to fine tune where I wanted the rear to sit. By the way, if you have Hotchkis springs up front, you might as well go Hotchkis in the rear since they've put the package together with lots of R&D and call it their TVS system. Consider cutting off the existing mono-leaf spring plates and either welding on new multi-leaf spring plates, or using a bolt-on kit. You could get away with the DSE mono to multi conversion kit for normal driving, but this would not be a good choice if you're going to drive the car hard or want to add a lowering block again.

As for the shock situation, I used DSE's lower shock plates for the '67. http://www.detroitspeed.com/1967-1969%20Camaro-Firebird-Products/040301-shck-plts.html
They are thicker than stock and have a strong, single-sided shock mount (factory lower plate supports the shock on both sides of the eye). Just make sure you have a sharp drill bit. :) You'll have to redrill the U-bolt holes in the shock plate for the larger diameter U-bolts that come with the Hotchkis leafs and the thickness of the DSE plate will require a good drill, a sharp bit, and a little patience.

Here's a pic of the DSE plates and Hotchkis multi-leafs I put on.

Mate, what shocks did you fit, I’m installing 3inch drop Hotchkins springs with DSE bottom plates and need shocks!!! Part no. Too please

Uhhh, that post was from eight years ago, and he has not been on the site sine 2013.

Those are Bilstein shocks. Hotchkis has their own shocks as well that will be a good match for what you have. I too have the DSE lower plates and Hotchkis springs.
