Post subject:  Offset Control Arm Bushings or New Bolts

looking for opinions.
Install the offset upper control arm bushings or
something like QA1 "Camber Bolt Adjusters"?

What do you think?
Street Car, some drag, but no road racer.

Those are just replacement cam bolts. They won't give you any more adjustment than stock. If you need or want more negative cambet or positive caster you need offset bushings or different control arms.

thank joshua, they make it sound like you get additional travel with bolts.

2nd Josh's statement. Gotta love that slippery marketing language...

With MOOG bolts you get 1 1/8 (+-), so if QA1 gets 2.5(+-), thats alittle better.

The cam bolts can't travel any farther than the slots in the chassis.

so are they only meant to be used with the Moog Eccentric Bushing Kit ? :?

No, it means that they can't do anything that the stock cam bolts don't do already.

I'm total confused, aren't these measurement measured off the center axis of the bolt. :?

The slot that the camber/caster bolt slides in when its eccentric is rotated can only travel as far as the width of the slot regardless of how offset the eccentric is. If one were to install Moog problem solver eccentric bushings correctly the range of adjustment will be increased to provide additional caster. These offset bushings relocate the upper control arm’s axis for additional plus caster adjustment.

after looking at the bolts alittle closer :shock: I have a fair understanding, but until I get into the frontend rebuild I am still mystified by mopar suspension/adjustments. I still like Slants! (the rest of the mopar mystique eludes me.)

So are 95% of alignment jockeys found under America’s frontend alignment racks, and that’s the point, Mopar has adjustments unlike today’s junk with huge sloppy rubber bushings and only camber adjustment.

Once you get up under there, it's pretty easy to figure out. The upper control arm (UCA) mounting bolts sit in slots on the frame, so that they can slide in and out to change the position of the UCA. Their position is controlled by those big eccentric washers, which push against little rails on either side. The washers are locked from rotating on the bolts, so turning the bolts also turns the washers.

If you want more negative camber, turn both bolts in such a way that the UCA is pulled in toward the center of the car. If you want more positive caster, you want the upper ball joint to move backward. So turn the rear adjusting bolt so that it pulls the back of the UCA in, and/or turn the front bolt so that it pushes the front of the UCA out.

The MOOG offset bushings don't increase the range of adjustment, but they do offset the range of adjustment depending on how they're installed. If you install them with the holes closer to the ball joint, you're effectively shortening the UCA and shifting your range of adjustment towards more negative camber.

And, if I understand correctly, maximum positive caster (with stock control arms) can be achieved by using offset bushings front and rear and doing both. Right??

not using standard arms.

and I bought a set of the QA1 Camber Bolts and they are a bit stouter than the stock or Moog.(Nuts,Bolt & washers)
