Alcan Springs and Orbit Eyes

[Dave18]

At 165,000 miles, it looks like it's about time to replace my leaf springs. I daily drive this truck and use it for camping and off road trips most summer weekends, so I'm not opposed to spending a little bit of money for good ones. I'm considering Alcan since I'm in Colorado, and I've heard good things. Does anybody have experince with them on a Ranger, and with the "Orbit Eye" bushings in particular?

I like the idea, but don't know how much more of a hassle they are to install or if they have longevity issues over a conventional bushing.

Thanks everyone!
