We have been putting Anti-rolls in cars since the 80's and this one is defintely the best we have ever came up with. Actually a customer from Canada turned me on to these bearingsd I have been using them ever since. You see when things twist they don't do it in a straight line and they don't do it evenly. Our sportsman style has been working for nearly thirty years and is perfect for those with an average horsepower range under a thousand horses. When you start attacking the strip with 1500 hP things really start to change. First off you can no longer deak hook that much power you need to get it up on the tire. Doing this means walking a fine line between being hooked and blowing the tires off. We have found that controlling the rocking motion helps keep all of the other things in balance to keep the car straight off the line. When you put that much stress on the anti-roll arms and tubes and run them through bearings they can go into a bind and not let the suspension work the through the shocks like it should. With these lrge lightweight composite COM bearings the whole ball swings however it needs to while transferring the load to all areas of the composite race.
Not only have I never seen one of the bearings fail but I have never had anyone wear them out either.
As much as people like these on the starting line they like them on the finish line too. Cars like to rock around on the big end but not with this thing. When you get out of the throttle this thing keeps everything happy while you try to slow that monster down.
