I got asked by a customer about roller spring perches of which I had to respond that I don't currently make them. His gripe about existing roller perches is that they make the car sit up higher in the front. Cobra Automotive makes a nice set of bushed spring perches using oil impregnated bronze bushings that probably don't increase ride height...it's a nice clean design, but they go for $339. :-/
So...i've come up with a design that won't change the ride height. I'm using COM-12 3/4" Teflon lined spherical bearings with chrome moly bearing cups and a 3/4" shaft...probably 4130 chrome moly. The spherical bearings are load rated for at least 20,000 lbs each or 10x the load that the roller bearings are rated for and they are PTFE lined for self-lubrication.
Here are some pics of a prototype that I hacked up to show what they look like. Still have some work to do on these and some testing. I haven't settled on a price yet, but they will be competitive with the roller spring perches out there now, but much higher load rating and no change in ride height.
