Question:

I have a 2024 GMC Sierra 2500HD Denali Ultimate. This truck has a 2.5inch hitch receiver, but I use the adapter sleeve to accommodate my Blue Ox weight distribution hitch. Which Rock Tamer model will I need to buy 2inch or 2.5 and will it work with the Blue Ox? ALSO, the exhaust from the truck is on the right rear pointing behind the vehicle. How do I protect the Rock Tamers and will the proximity of the Rock Tamers to the exhaust be an issue for the truck?

Hi David,

Rock Tamers require an inch of space on the ball mount shank in order to mount. If the portion of the shank exposed where you'll be installing the Rock Tamers is 2" x 2" then you'll want # ERT00108, for 2.5" x 2.5" you need part # ERT00110. The WDH shank should be what you're going off of so 2" is more likely what you'll need. Rock Tamers offers a bolt-on heat shield # RT76FR to help protect the flaps from the exhaust. If you ever change out the WDH with something that has a 2.5" shank you can just swap the center hub with part # ERT057.
