Spherical Leaf Spring Joints for '67-'81 F-Body

[F-Body International]

Anyone have some good opinions or experience with this stuff? How come many of the performance guys with muscle car leaf springs use spherical only in the front then have delrin/delalum/rubber/poly out back?



I don't have PTFB, ridetech or any other brand spring measurements but Hotchkis Suspension website states their springs are 2.5" wide with a 2" front spring eye and a 1.6" rear spring eye. I assume this is a similar measurement across many of the spring manufacturers for 2nd gen F-Body. All the ones listed below are roughly consistent with the front eye measurement considering what the Hotchkis website provides for measurement. The Deaver piece listed at the bottom is about equal to the rear spring eye on the Hotchkis measurement. This is what I've found but please feel free to provide any more sources for this type of suspension equipment if known.

Alcan Spring Orbit-Eyes
http://www.alcanspring.com/orbit-eye.htm
You may already know that Alcan Spring built all of AOR's famous, super-flex Orbit-Eye™ Springs. AOR supplied the Orbit-Eye™ Joints; we perfected the custom spring design that the Orbit-Eye housing's 2.5-inch diameter requires. So, fabricating these custom world-class, off-road leaf springs is nothing new to us. What IS NEW is that we've acquired from AOR the exclusive rights to the Orbit-Eye™ Joint itself. And we can now build custom Orbit-Eye-equipped leaf springs in a huge range of lift heights and load capacities for your Ford, Chevy, Dodge, Jeep, Nissan or Toyota. What's more, the Orbit-Eye™ has been redesigned & refined. It offers vastly better flex, performance and durability than ever!
* A full 46° of flex - Up from 38° (SCROLL DOWN if you're not sure why this is a good thing)
* Precision-machined, cold-rolled steel ball rides inside a special molybdenum-based nylon socket. Housing pins secure the socket in place.
* Rustproof aluminum spanner nuts secure the ball-and-socket inside a .120-wall steel housing. Set screws prevent the nuts from backing out.
