Vehicle Fitment - Compatible with RAM 1500 Quad Cab & Crew Cab (2009–2018), RAM 1500 Classic Quad Cab & Crew Cab (2019–2023), and RAM 2500 & 3500 Quad Cab & Crew Cab (2009–2026) equipped with split bench rear seat. Does NOT fit Mega Cab models. Pry-Guard Keyed Lock System - Integrated 10-tumbler double-bitted keyed lock combined with the Pry-Guard locking system and built-in weather seals to enhance resistance against prying and tampering. Welded Steel Replacement Lid Construction - Reinforced welded steel lid replaces the factory plastic folding platform, creating a concealed and lockable underseat storage compartment with durable powder coat finish. Continuous Hinge & Rattle-Reduction Design - Features a continuous welded steel hinge and integrated bumpers to reduce vibration and support secure lid operation. Installation Requirements - Installs using original factory mounting points with no drilling required on split bench rear seat models; full bench rear seat vehicles require drilling one hole and use of a user-supplied 3/8-inch bolt to secure the inner-rear corner.
