Hello Members,

Well not a new item on the market or anything but a new item for us. We now offer a non-adjustable upper A-Arm. Thanks for looking!

Looks good. Need lower a-arms like those now.

We may do a lower with polyurethane bushings in the future. However the downfall is you can only use a poly bushings on one side, the other side would still need the spherical rod end. This is due to the way GM has a "swivel" rubber bushing from the factory. To put poly on both ends would cause some serious binding issues.

Thanks for the comment!

Do these give more neg camber or pos caster than stock (like say..GW a-arms), or is geometry same as stock other than the ball joint angle?

Geometry is all the same except the ball joint angle. For cast and camber adjustment we use our adjustable set-up # 2310 www.umiperformance.com/2310 this make you make your changes where you want them to be.

Yeah, I saw those. I'm a little hesitant to put rod ends up front though...this is still a street car. I realize rod ends are the best for performance, but I really don't like the noise and harshness on the street. I'd like to find a happy medium.

Nice to see you guys building the non-adj uppers, I'm sure many would like to see the "mostly" non-adj lowers too. I'm with subtlez on his last post about the happy medium.

If you decide to go that route With one sperical end, can you include a dust boot with it. It helps quite a bit for us the DD guys. This is one of the main reason I stay away of the spherical ends. They just don't last long enough.
