I believe the adjustments in the trailing arm crossmember serve a similar purpose as the holes in the trailing arms for the crossmember. You can adjust the trailing arms to the best hole to minimize movement front to back. As for the trailing arms themselves, they are much more than a stock replacement. I didnt weigh mine either, but I would say they were equal or more weight than stock. However, the stock arms are 2 c-shaped tubes riveted together to make an I-beam, and water and road crap settle in the middle, compromising the bars when it rots and rusts. That's the reason my stockers broke, so watch out that you're not stranded one day... The PB arms are top quality, and the best part is getting rid of those old loose rubber bushings!
