The Multi-Flex™ / MultiPro™ Tailgate Hitch Solution

Protect Your Tailgate from Costly Damage

No splicing wires or buying a separate hitch!

The GMC MultiPro™ / Chevrolet Multi-Flex™ tailgate is an exciting innovation for pickup truck owners, adding functionality and more ergonomic access to the truck bed.

When towing a trailer with your GMC or Chevrolet truck, it is important to protect the inner tailgate. If a hitch accessory is installed in the receiver, folding down the inner panel could result in costly damage. GMC MultiPro™ tailgate replacement cost can be as much as $3,000 and adds downtime for your truck, and alternative tailgate sensors are expensive and require cutting and splicing.

Introducing the GM Tailgate Sensor

The CURT protective MultiPro™ / Multi-Flex™ tailgate sensor prevents costly damage to your truck’s inner tailgate from obstructing a hitch accessory. The sensor is integrated with a standard hitch cap and disables the inner tailgate functionality when any shank is installed in the receiver.

The CURT protective tailgate saver turns any ball mount into a Multi-Flex™ or MultiPro™ tailgate hitch, ready to get the job done! It is available in standard 2” and 2-1/2” receiver options and can be installed easily with no splicing required!

Tailgate Sensor: With vs. Without

With the tailgate sensor, the Multi-Flex™ / MultiPro™ inner tailgate is disabled with a ball mount or other towing accessory installed in the receiver. This prevents obstruction and costly damage.

Without the tailgate sensor, the inner tailgate is able to drop down and collide with any hitch accessory in the receiver. This instantly causes damage to the tailgate, resulting in expensive repairs.
