What kind of A-arm bushings do you guys run? I just purchased a 76 nova street stock & the front bushings are hammerd. I was wondering about poly or stick with rubber?

Put new stock bushings on the upper A-frames and make sure the A-frames can move freely up and down. The steel bushing offered by Afco are good pieces, however, they are costly. A-frames are disposable pieces on a "street stock" type car and those Afco bushings are weld in. So, you bend an A-frame with Afco bushings it costs you twice as much. I don't believe you'll ever wear out stock bushings if they are installed correctly.

Wear is not the issue here. Metal bushings
provided a much tighter suspension than the
rubber ones. You want predictable suspension travel. Rubber bushings will flex. The only
rubber you want anywhere on a SS is tires, belts and hoses. Get ride of all the rubber in your suspension compontents and mounts.
If you cannot run metal, at least use the polys.

Urethane in both uppers and lowers of my 85 Regal. No steel for the same reason that cmiller said...

for the steel bushings all you need is 3 little tack welds and if you bend a a-arm all you do is put the bushing in a different a-arm

One down side I have seen on these. If they rust or start to rust or get any trash in or around them, they will bind. I had some that actually siezed up when the grease fitting came out.

The steel bushings can be a maintenance nightmare. If you don't grease them after every race they will sieze up and cause a nasty push. The zirk fittings turn in the bushings after each race so you gotta get them turned back around to grease them and, like Jammin said, the grease fitting can fall or back out and then you've got problems too. The mounts on the a-arms can get all bent out of round, too, with steel bushings if you race a rough track.

Don't get me wrong, I like the way they free up the A-arm movement, but they are troublesome for maintenance. Give me the poly bushings any day.

The poly bushings are what we went to in our mods. When the steel bushings bound up, your done.... You don't have a choice but to take them out. They will completely bind up your front suspension. The poly bushings are pretty hard. They will allow a little flex, but if I dont have to take them out 3 times a year, I think it is worth it. I think I like these better already.
