Mono leaf springs

Anybody tried these?

What did you think?

Would you do them again.

Thanks.

Yes.

Not a good idea.

No.

You're welcome.

P.S.: To elaborate, a leaf stack lets you break a leaf and keep going. Break a mono, and you are in a heap of bad news and out of control. GM tried them for a while and changed within a short time back to stacks or coils.

P.P.S.: Welcome to FTE!!!

Not to be rude, but this topic has been beat to death online. I'm done discussing it, but have a suggestion that will help you.

Please read every word of this page:

Mono Leaf vs. Multi Leaf Spring

What would cause them to break?

I have had them on other vehicles (cars and vans) without any issues and thought they would improve the ride and handling on an older truck as well.

Other than breaking what problems would there be?

Thanks.

Welcome to FTE, Vic. Other than breaking, there's the reduction to load capacity. Even with a "show" truck, the bed itself weighs quite a bit, add to that any payload, and it only gets heavier. Posies makes a dual spring set-up that would work better, and shouldn't cost much more than monos? IMO, spring-under-axle (rear) and a different front end would be better than monos. I personally shy away from monos due to the potholes and frost upheavals in my neck of the woods. I'm going with reverse eye mains and every other leaf removed, which in theory should equal to the amount of drop a mono leaf will provide.

I know leaf springs can break, but I have owned seveal cars and trucks with leaf springs and only had one problem in an older Camaro. I have a 62 Nova with the original mono leafs in the rear. The ride is good and the suspension is solid. This car has a stock 350 and a 350TH.

What did you hit to break those springs like that?

I have used mono leaf's front and rear with good success both ride and reliability.

Seems like mono leaf's would be just the thing for these old trucks. Just by chance I drove a 53 last weekend with mono leafs that were ten years old. Nice ride and the truck was lowered 3" with those springs.

Have there been alot of problems with mono leafs? I have never heard of any.

Thanks.

VV

I just put monos front and rear on my 52 F-1 that is mostly unrestored original. It lowered the truck considerably and didn't compromise the ride, in fact it improved it. However I have probably less than 20 miles on them so far and plus I live in Commiefornia and my truck gets stored during the winter months. I spoke in depth with the guy at Durant Enterprises before I purchased my springs and he told me he has yet to have a problem with any of the springs they sell as far as any breakage is concerned. I too have read the horror stories about mono leaf springs and I think it really all comes down to personal preference, It's your truck so do what you want not what others tell you to do.

True, it is a matter of personal preference. You will notice monos are a thicker steel than a main leaf is, and that is what allows them to work by themselves. However, daily driving exposes them to more stresses than a stack of leaves will, and it is only a matter of time before they either sag or snap. Rust is their biggest enemy, so staying away from winter will net more longevity out of them. Just my 2 cents.
