The Burning Rom. Think Energy Suspension!!!!!! the bushing for the Gen2 bar is the same as the Gen 3 bar except on both ends. And the bushins is available for <$20 for 2. So when the bushings wear out, replac with urethane bushinss fom Energy Suspension. Thats the way to go.
i still don't like a hein joint for a trackbar. The 2003+ trackbar motion is linear.

 

I'm running the 03+ bar on my truck. I only have about 1000 miles on it so I can't attest to durability yet, but I've never had a problem with the bushing wearing out on my old bar...it has always been the ball joint end that wore out.
