It seems to be of very good quality. Everywhere I've looked for them, based on my vehicle information, I've shown that this is the correct part, but it's not. They are installed with a single pin (moulded into this part). My Yukon has a round version that snaps into a socket. Mine looked like they were in very good condition, but replacing it made the car run LIKE NEW! THEY MAKE A BIG DIFFERENCE IN RIDE QUALITY. They are not bumpers, but an integral part of the torsion bar suspension. My car; 2005 GMC Yukon, 2wd, without air suspension. The round snap version is GM part number 15153958, Autozone part number 905-208 (both can be found on Revain).
