Question:
I have a 2005 GMC Yukon XL Denali AWD. I no longer use the factory air ride and replaced the shocks with Monroe Coil Spring over Shock. I will be buying your Curt Class 5 Hitch and 1000/1500 lb. Curt C17501-WDH within the next two months. And interested installing these TGMRSB4S to replace the old bump stops. To pull my 27 Toyhauler. Can these bolt in place as showed in pic bolt onto my Yukon XL ? I read reviews where without bolts very hard to seat into place ! Now I see these for sale with bolt and plate. Thanks Charlie

Hey Charlie! The Timbren item # TGMRSB4S isn't going to be a fit because it only works with the 2500 Yukon's. From what my system tells me the 2005 GMC Yukon XL Denali AWD is a 1500 model. In that case you would need the Timbren item # TGMRYS4.
The Timbren item # TGMRYS4 do bolt up where the bump stop used to be. I have linked an installation video below along with the instructions so you can see how easy these are to install.
To answer your question though. Yes, the Timbren item # TGMRSB4S do bolt directly to where the bump stops are originally installed. It includes all the necessary installation hardware.
Additionally, the Curt Hitch item # C15324 you referenced has been confirmed to fit all models of the 2005 GMC Yukon XL. It will definitely work with the Curt TruTrack Weight Distribution System item # C17501.
