Re: Anti roll bars.

Since there has been some ambiguous statements made by some of those who posted in this thread, I just thought I would point out something to prevent any confusion here for the original poster of this thread....


The HrPartsNstuff bar, BMR Fabrication bar, and the Spohn Performance bars ALL bolt directly to the frame of the car, and to the axle tubes, NOT to the rear control arms like the GM "anti-sway" bars do. I don't know about the UMI bar, (that one might mount the same way as the other three do. I don't know). All three of those bars mentioned are bolt-in ANTI-ROLL bars which have a huge 1/38" diameter and are much stiffer than any stock type, or aftermarket "swaybar" is. I installed the BMR fabrication bar on my Chevelle. It required four holes to be drilled into the frame. That's it. No welding required, and the bar is so stiff that when you raise one side of the front of the car with a floor jack in order to lift the front tire off the ground, the rear tire on that side of the car immediately comes right off the ground with the front tire. These are NOT "anti-sway" bars at all. Big difference.

Correct, our design is the same way. It bolts to the chassis and requires 4 holes to be drilled. A few little tricks we add to the bar include a hollow bar which is 12lbs lighter, a design bent around the rear end pumpkin rather than under it, this prevents ground clearance loss and lastly, we laser cut teeth into our axle mounts to prevent the bar from rotating. Our design also automatically comes with heavy duty aluminum sway bar brackets.

Hope that helps,
Ryan

Re: Anti roll bars.

In the interests of giving honest credit to the engineering, originating, trail-blazing pioneer of the ARB-swaybar used for straight-line traction, credit rightfully belongs with SPOHN. The next 2 companies offering ARBs were selling blatant brazen bold straight-up copies of the SPOHN unit. No names necessary. <END>
