Which Auto-Slider Hitch for 2021 Chevy Silverado 3500 Compatible with Underbed Mounting Kit

Helpful Expert Reply:

I have a solution for you, but there is not an aftermarket OEM puck style system for your 2021 Chevy Silverado 3500. However, you can use the Demco Hijacker Auto-slide Hitch 21k # DM8550037 with the underbed mounting kit # DR37FR to give you exactly what you're looking for. The Hijacker Auto-slide is a great choice that you'll never have to worry about getting out of the truck to engage the slider.

The Underbed Rail and Installation Kit for Demco Hijacker UMS 5th Wheel and Gooseneck Trailer Hitches # DR37FR will install hidden so that you'll have the clear truck bed when you're not towing your 5th wheel. This would be the only option available for both an auto-sliding hitch and under-bed mounting.

I've linked a short review video on the Hijacker for you to check out.
