Rear spring eye bushings

It's become common practice to put polyurethane bushings throughout the front end of cars anymore but is anyone doing it to the rear?

Yep, got a set for the 68 that is getting new springs and a Dana. There are aluminum front eye bushings available as well....but i opted for poly all around (front/rear). The oem style rubber tends to deflect under load....the poly corrects that.

But with rear leafs (leaves?) isn't the spring going to do that anyway?

There is minimal torsional twist in the leafs themselves.....the majority of it comes from the bushings. Rubber is the worst by far. The downside is a slightly harsher ride. It's not something i would do on a cruiser but for a street/strip car it's essential, inmo.

Even if the strip portion were only two or three times a year?

either way, the poly will last 3x longer than the rubber.  the rubber will begin to dryrot whereas the poly will stay true.

:iagree: The rubber starts to break down and will deteriate faster with hard launches....street or track...doesn't matter where you're doing it.   :drive:

Like i said earlier the only application i would use rubber is a cruiser where ride quality was more important than performance and longevity.

I would use poly in the rear also
