Hotchkis swivel eye bushing for rear leaf springs

[RAnthony97]

I didn't realize Hotchkis sold swivel eye bushings (http://www.hotchkis.net/swivel-max-bushing-upgrade-19671981-camaro-firebird-6874-nova.html) for rear leaf springs. Are they a new product? Anyone use them before?

Hotchkis had told me they were developing them for a 2011 release so yes they're new. I think Carl Casanova's 68 camaro was instrumental.

Sooo... Expecting Hotchkis will be along here soon.

Will these be listed as an upgrade to the rear springs out the door?

Listing them as an add-on to a set of springs and deduct the other shackles/bushings seems like a simple and logical option to make available.:yes:

[Jay Hilliard]

cool, but the price ($330) seems steep to me. I guess you have to pay to play.

[Hotchkis]

Hey All – These are brand new parts that we’ve been testing for a while with great success!

Offering them as an option with the springs is a great idea. We’ll have to look into the option of offering them in the springs we sell, but you can always call us and maybe something can be worked out until we get that worked out. As far as pricing goes, we always have to weigh in cost of materials and production along with other factors. These new shackles are definitely making a difference out on the road and the track. Keep watching for new products! We’re always up to something…

I love it when I'm right.:D

Actually, I think the price is almost the same as my marketing consultation fee so when you get my invoice just send the parts and we can call it a done deal. I'm fair like that. :thumbsup:

:unibrow:

On the website, "Highest quality PTE lined mono balls"
Can you explain PTE? I am not familiar, was that to read PTFE (Polytetrafluoroethylene)?
:question:

I have the Hotchkis springs in th rear and I'd love to swap out the standard bushings for these.....

Roberts68 – Thanks for being fair with your “marketing consultation” and also for pointing out the PTFE. We’ll have our web guy look into that.

Please can someone explain how these are a improvement over even Delrin bushing shackles.

The spherical bearings eliminate binding as the car rolls. With rubber or Poly bushings, the rear get's stiffer and stiffer with every degree of chassis roll due to bushing compression. This can cause corner exit oversteer.
Pot holes and tar strips will be felt more with these, but the rear feels more precise. Type of tire matters too, a tire with more tread feels pretty good on the street, but 100 tread wear tires with very little tread feel harsh.

David, So would say that a street car that will see a track or auto cross a few times a year benifit from these or not really?

He looked into it so good the website is offline :).

Looking forward to these :hail: .

[garymac69]

Can we get before and after test results on these bushings?

[GaRys69]

So would this be an improvement over greased up Delrin bushing shackles?

There is benefit, I'm not sure how much. When we switched to this type (Cat 5) the rear felt more precise & it let you know what was going on back there a little better. We have this Hotchkis system on Deanna's second gen Camaro which is winning.
In a back to back test, comparing it to Delrin/Poly bushings, I think the difference would be small. No way do you ever want a solid delrin or aluminum bushing up front on a leaf spring. It would cause corner exit oversteer due to binding. A solid bushing on the rear leaf eye is not so bad, but a stock front & poly rear on the leaf eyes is next best to this system.

Just trying to connect the dots here.

As far as a leaf spring rear suspension is concerned, this setup with an adjustable sway bar, PTFB comp rear leafs, would be the cats meow as far as a leaf sprung suspension could be for a autocrossed car that gets driven on the street.

How would a watts link affect a setup like this? Would it interfere with the already limited side to side movement?

[Bryce]

A watts link defines a roll center the leaf springs also define a roll center. If you matched these roll center you would have less bind.

I would use these and a spherical in the front spring eye.
