Proven Locks' adjustable drop hitch collection delivers heavy-duty towing solutions for trucks where the factory ball height doesn't match the trailer coupler — the everyday reality for anyone who tows more than one trailer. Adjustable drop hitches let you dial in the exact drop or rise for a level tow, and this collection pairs that versatility with GusHillUSA's locking-pin security so your hitch setup is tamper-proof from ball mount to receiver. Rated up to 16,000 lbs with drop sizes from 3" to 9".

A trailer that sits nose-down or nose-up while towing causes uneven tire wear, swaying, and is a safety risk at highway speeds. An adjustable drop hitch eliminates the fit problem, and the included locking pins mean your setup can't be quietly removed while parked.

  • Adjustable drop sizes: 3", 5", 7", and 9" — covers most truck/trailer height combos
  • Receiver sizes: 2", 2.5", and 3" for all truck classes
  • 2" and 2-5/16" dual ball mount included — one kit fits most trailers
  • Pintle attachment included for lunette-ring trailer compatibility
  • Locking pins included — security is part of the kit, not an add-on
  • Up to 16,000 lbs towing and 1,600 lbs tongue weight capacity
  • Designed and fulfilled in America

Made in USA  |  Free Same-Day Shipping  |  Lifetime Warranty

Select your drop size and receiver size to find the right adjustable hitch for your truck and trailer combination.
