Bolt torque for aftermarket brackets?

I was removing my control arms to check bolt holes for wallowing. I noticed that, despite being torqued to at least 125 ft lbs, the arm rotated fairly freely in the axle side bracket (once I removed the frame side).

Is this due to the less tension on the arm bushing, caused by less flex in my aftermarket axle side control arm bracket? I've got grade 8, finely threaded 9/16 bolts, so should they be torqued too like 150+ ft lbs? Same thing on track bar brackets?

What brand of bushings do you have?

Metalcloak. But the same question would probably apply to any stock style ones as well.

Stock clevite bushings only flex as much as the rubber can deflect. The metal portions do not move against their mating surfaces, and the rubber is bonded to the metal portions of the bushings. Metalcloak bushings do allow the outer surface of elastomer to slide around the metal housing that is welded to the bracket (R passenger side) and pressed in (L driver side). The bolts should rotate with the arms and bushings (the bushings may twist a little before the outer part breaks loose and starts sliding but you may or may not see that); and you should not be seeing any sliding between the bolt and the bushing, but I think that might be hard to see. You're fine, and I'd recommend staying with stock torque specs, and verify your lock rings are seated properly.

It's also never a bad idea to just call Metalcloak with your questions. They give excellent customer service.

Not sure if I quite follow you. From what I can see, the bushing and control arm seem to be fine. The bushing flexes a little as it should.

Where I'm seeing the fairly free movement is between the bushing and the axle bracket (lower arms). The bolt doesn't move, the bushing doesn't flex or rotate within the arm end. The whole thing moves fairly freely inside the axle bracket and around the stationary bolt.

Lower arms ah ok. The lower axle side bushings should stay fairly fixed relative to the brackets, and the arm end (bushing housing) should be rotating around the bushing. Give Metalcloak a call for the definitive answer.
