The PullRite 4452 adapter converts an industry-standard, tabbed-foot hitch base - including PullRite's ISR series - into an OE puck-mounted setup for 2020 and newer Chevy/GMC trucks equipped with factory pucks.
It centers the hitch over the rear axle for better towing balance and handling, breaks down into four individual pieces for easier handling, and uses four independent mounting posts. No tools are required to install or remove it, so you can pull the whole rail system out for a clean bed when you're not towing.
Kit includes adapter rails and mounting hardware. Confirm your truck's model year and puck configuration before ordering.
