I've never had a problem with any of my other trucks. That's why I gave it a good rating. The specific block listed as fitting my 2011 Denali 2500 does not fit. It is about 2 cm too short. The mounting bolts were bent and the bushings failed after a week of riding. before you install them. Rotate the steering and compare the mounting holes with the stabilizer bar extended and compressed to make sure it fits. now the happy owner of a crappy stabilizer.It can serve as a target, that's all.
