This kit raises the rear seat and back 2 inches and is designed for the 2019 through 2021 Chevrolet and GMC Trucks that are equipped with the Cargo Bin or "cubbies" as some call them. Starting in 2019 some Denali and High Country trucks were equipped with this style seat.
Beginning with 2020 trucks they could be equipped with the Cargo Bin style seats using THIS KIT to raise them.
Some of the 2020 trucks have a seat back that is fixed to the back of the cab and does not move, and does not have Cargo Bins. We do not have a product for those seats at this time.
If your seat back moves up and down when the seat bottom is raised and lowered then THIS KIT is the correct one.
