CURT – Double Lock EZr Gooseneck Hitch (Part No.60611)

Double Lock EZr Gooseneck Hitch

from

$337.99
A CURT gooseneck hitch is more than a necessary tool for towing; it is an integrated extension of your truck that allows you turn your 4×4 into the workhorse it was designed to be. Gooseneck hitches are stronger, tougher and more subtle than any other, and when quality craftsmanship and intelligent design become the fuel that drives a gooseneck hitch, you get a towing solution that leaves others lost for words. The CURT under-bed Double Lock EZr gooseneck hitch is strong, fast and easy to operate. It gets its name from the two locking pins that engage the trailer ball and hold it in place, giving you twice the security when towing especially heavy trailers. The Double Lock EZr mounts underneath your truck bed with compatible gooseneck installation brackets and provides a removable 2-5/16″ gooseneck trailer ball with a gross trailer weight capacity up to 30,000 lbs. and a tongue weight capacity of 7,500 lbs. Using the heavy-duty operating handle, the trailer ball can be unlocked and flipped over whenever necessary to allow full use of the truck bed. For easy one-person installation, the Double Lock EZr comes with the CURT-exclusive center locator. This simple installation tool inserts into the gooseneck trailer ball hole during installation and shows exactly where to drill in the truck bed, eliminating errors and the need for meticulous measuring. The Double Lock EZr also comes with solid safety chain hookups, an attractive chrome trim ring, a durable carbide powder coat finish and a limited lifetime warranty.

Product Features:
  • One-person installation requires no welding or truck bed removal
  • Center locator eliminates the need to measure where the ball hole should be
  • Double locking pins for superior trailer and trailer ball security
  • Flip-and-store ball keeps truck bed free of obstructions
  • Removable chrome-plated 2-5/16″ trailer ball fits most gooseneck trailers
  • Chrome-plated trim ring provides a finished look
  • Rubber hole cover helps prevent corrosion in trailer ball hole
  • Heavy-duty 3/8″ diameter handle for solid operation

Double Lock Gooseneck Installation Brackets

$354.99
Choosing the right gooseneck hitch is only half the battle in preparing your pickup truck for towing a gooseneck trailer. CURT gooseneck hitches are a premium option in the heavy-duty towing industry, but they are only one of the members in the heavyweight tag team that is CURT gooseneck towing. While a gooseneck hitch gets all the glory above the floor of your truck bed, gooseneck installation brackets provide sure footing and a solid foundation for that oversized gooseneck trailer. Gooseneck installation brackets work by bolting onto the frame of your truck, typically using pre-existing holes. With a set of brackets firmly bolted on, a gooseneck hitch is able to be attached and is given the strength it needs to manage the massive amount of weight of a gooseneck trailer. With so many gooseneck hitch options available from CURT, we wanted to make sure we offered the gooseneck installation products needed to give you a complete towing package. Our installation brackets fit multiple vehicles and hitch heads. This particular set of gooseneck installation brackets is designed to work with CURT Double Lock gooseneck hitches. It is rated to the vehicle’s maximum gross trailer weight capacity and provides a custom fit for certain years of the Chevrolet Silverado and GMC Sierra 2500HD or 3500 (see application info to verify fitment). With each gooseneck installation bracket sub kit, we provide the necessary hardware for an easier installation, and we coat our gooseneck brackets in a liquid A-coat to make sure rust and other potential damages are not a problem.

Product Features:
  • Mounts the Double Lock gooseneck hitch on specific pickup truck models
  • Vehicle-specific design optimizes strength and installation time
  • Constructed from high-strength steel
  • Protected by a rust-resistant liquid A-coat
  • Includes grade-8 mounting hardware
  • Rated to vehicle’s maximum gross weight rating
