Calvert split mono leaf spring & pads

Hi all,
Just bought some Calvert split mono leaf springs for my 68.

Do I use the upper and lower rubber spring pads from the original springs with the Calvert springs?

Not 100% sure (I don't have them) but I think they are suppose to be left out and there's not room for them anyway.

Re: Calvert split mono leaf spring & pads

What sping perches are on your differential....mono or multi? Does the perch have a cut out that the leaf spring pin sits in to center it?

Re: Calvert split mono leaf spring & pads

Just saw your other post....if you bought the spacer kit from Calvert that is all you need.

I have a 12 bolt Moser with single leaf perches

These are the springs and spacers


This is the pin on upper face of spring (I am assuming the spacer is located on this "pin")




This is the underside of the spring / pin (which is basically the nut on the thread of the pin) I assume this locates in the hole of the spring/shocker plate

Re: Calvert split mono leaf spring & pads

Mine are multi perches so the spacer kit had one for the top of the spring and one for the bottom. I guess the mono has top only. Anyway, definitely no need for the rubber spring pads witih this setup.

Re: Calvert split mono leaf spring & pads

Thanks for the info and photo.

Do you think there is any extra noise when comparing old spring with rubber spring pads to the calvert spring with steel to steel?

Re: Calvert split mono leaf spring & pads

I just purchased the spacers for my 67 Camaro to install the Caltracs. They sent me the uppers you have and a pair for under the leaf springs. The bottom spacers have a larger sleave to fit around the nut on bottom of leaf spring. Looking at the new spring pad the hole is large enough to bolt together without the bottom spacers. Good Luck.

Re: Calvert split mono leaf spring & pads

I don't think the pads will contribute to noise much but it has been a loooong time since I had rubber pads and can't really remember.

The only squeeking I ever got was from the front spring eye bushings if I had negative preload on the bars (an actual air gap between the stopper and the spring). It was not bad and went away now that I run the slightest pre-load.

Re: Calvert split mono leaf spring & pads

Ok, so now I know I should have the spacer on the top of the spring but I have another issue / question.

The nut on the bottom of the spring seems to be a lot smaller than the hole in the shocker plate (see pic)

Am I missing something that will locate the spring / nut positively into the shocker plate?
I am concerned I will get some movement which could cause bigger issues over time.

Re: Calvert split mono leaf spring & pads

What exactly is the spacer kit for? Are you able to get the ride height you desire and is there any problems with adjusting pinion if needed. I've been looking at these for a while.

My car is originally mono leaf and when I purchased the springs from Calvert they advised the spacer is required for cars with mono perches.

Re: Calvert split mono leaf spring & pads

Nev,

If you have enough threads on the center bolt get a thick washer or sleeve made that fits the hole diameter of the lower shock plate and install it under the nut to locate the shock plate.

Re: Calvert split mono leaf spring & pads

i wouldn't be afraid to run it as is but if you are worried, call or e-mail Calvert. I don't have a mono perch on mine so I can't really tell you for sure.
