This safe fits the new design 2014 - 2018 Sierra and Silverado with the split bench seat. One big change this year, is that the SLT and LTZ models no longer come standard with bucket seats and consoles. Standard is the Leather Split Bench Seat. This unit is for the split bench model and fits in the compartment under the center section. It will not fit the 2014 HD trucks (2500 - 3500) Use the LD2014. You will not be disappointed.
