Replacing A-arm bushings

In the front, rubber bushings provide a smoother ride and maintenance-free life... Poly bushings provide better performance, but require somewhat regular greasing. The "PolyGraphite" ones don't need the greasing, but they have a shorter life because the graphite actually breaks down the polyurethane.

What is "best" depends on your intended useage.

Bah... My car is dropped 4" already and I would drop it another inch if it wouldn't mess up the geometry.

Can't do that with long-tube headers though.

The response was Eibach doesn't offer a spring kit for BB Chevelles. I'm glad they were honest with me. I almost pulled the trigger. A word of advice to those thinking about buying springs for Chevelles, even though the application says all A-bodies including SS. You might want to ask if that includes BB Chevelles.

I wouldn't worry about that, the Eibach spring rates are around 550lb/in where stock smallblock are ~325lb and stock bigblock are ~375lb.

BB vs. SB might make a difference of about 1/2" with the 550lb rate, and most people end up cutting their Eibachs anyway. If they're too short, urethane spring shims (that go on top or bottom of the spring, not between the coils) are cheap and easy to use.

I was just kidding, I meant 2" springs, not 2" drop.
