I just installed the Dorman sway bar to replace my GMPP front bar. I used the Moog TPR (blue color) end links and frame bushings. I used the 1.26" (32mm) frame bushings, as that was the size of the crappy rubber bushing that came with the dorman bar, even though it measures a tad over 33mm with a caliper. I tried using the Moog 1.34" (34mm) frame bushings but they were too loose, the 1.26" bushings are nice and tight, but still move freely. I lubed them with di-electric grease.
I would think the dorman bar is 100% solid.. That sucker is very heavy compared to the GMPP bar, and seems stiffer.
I like the TPR (thermoplastic rubber) material. Its a little softer than most poly bushings, but much firmer than rubber. It doesn't squeak, and is maintenance free.
