I have stock bushings in my uppers and lower control arms with a swaybar (bad wheel hop) I was looking at some boxed lower arms that have aluminum bushings in them on ebay. Will those fix my wheel hop? How do these ride on the street? I drive it everyday to school. Or should I put some polys in?

I'd stay away from aluminum. Poly bushings still have some "give" so the suspension won't bind.

Wheel hop is often because the lower control arm is not parallel to the ground. If you raise the rear to clear larger tires, you change the angle of the lower arm, and the result is wheel hop.

GOOD bushings and proper geometry are often all it takes.

We are talking about rear suspension since I see wheel hop is an issue. NEVER use poly bushings in the rear of a converging link suspension. The suspension design has "bind" built into it already, poly compounds that infinitely. The Edlebrock arms with Al bushings in the axle and Johnny Joints at the frame are the best thing going if you want to retain the quadrabind suspension.

what are johnny joints??

Currie makes them. Picture a really big spherical end totally sealed from the elements with more range of motion. Edlebrock rear arms use them and Currie obviously uses them, I heard maybe Hotchkis may start building arms using them too. Johnny Joints (http://www.currieenterprises.com/cestore/johnnyjoints.aspx) and main page left lower box (http://www.currieenterprises.com/) shows the whole arm available.

Why is poly so bad, everyone seems to like it,I dont understand why these johnny joints are so good

I used aluminum bushings on the upper housing ears only with rubber bushings everywhere else. My Elky seems to like that combo pretty good. Ride doesn't suffer and with boxed arms I'm not having any wheel hop issues now.

Here is a post from a different board discussing the same topic, it should sum it up pretty well-

Just because everybody else does something doesn't mean it is the right thing.

Thanks agin for that link and super article Denny. I was weakening on the upper poly issue after seeing the Hotchkis kit. I thought, it can't be that bad or everybody would be yelling about it. Turns out, everybody already did. I'll probably go with their boxed lowers, a 1" sway bar, and Edelbrock uppers when I re-assemble my 67. Sounds like that's the best solution to a weak situation (converging 4-link). graemlins/thumbsup.gif
