Zip's HD Underreach Towing System

Note: Special Handling Fees Apply for Specific Items

This multi-purpose towing adapter from Zip's provides heavy-duty tow operators the versatility and flexibility to tow a variety of trailers with their underreach. Available in a seven-piece kit, the adapter stores easily and works with four different trailer attachments to pull anything from campers and horse trailers to pup dollies and gooseneck flatbeds.

Strong and durable, this welded steel adapter is powder-coated safety yellow for easy identification. To install, insert the two vertical 2" pins on the bottom of the adapter into standard fork receivers on the underlift's crossbar. The main pins are then secured in place with two retaining pins, which include two cable lanyards so they won't get misplaced.

Four attachments for this adapter are available for purchase separately or sold in money-saving kits with the adapter. Bolted on the side or pinned on top, these brackets include a pintle hook with a 2-5/16" gooseneck ball, a fifth wheel plate and a kingpin. Scroll down for more information on each attachment kit, and order the one you need from the drop-down menu top right.

Please note when using these attachments, it is important to not exceed the rated towing capacity of your wrecker's underreach and to follow the manufacturer's capacity rating tag. All attachments should be used in combination with tie-down chains for safe and road-worthy travel.

All attachments can be easily stored in a side storage compartment on a wrecker. When installed properly, the attachments sit proud of any obstructions on the adapter and allow for a wide turning radius, which makes for better maneuvers in traffic and around corners.

All steel parts feature a corrosion-resistant finish to extend the life of the adapter. Additional components and hardware are zinc-plated to further promote long-lasting performance, making this adapter a one-time purchase for any heavy-duty operation. This kit is a great alternative from the Miller Industries Heavy Duty Hitch Attachment Kit.

Master Kit
The Master Kit for Zip's HD Underreach Towing System includes the main underlift adapter as well as all four attachments: the gooseneck bracket and 2-5/16" ball, a pintle hook attachment, a kingpin attachment and the fifth-wheel plate adapter. All hardware is also included, such as attachment pins, retaining pins and four bolts.

This kit offers operators everything they need to tow a variety of fifth-wheel and gooseneck trailers - such as campers and livestock trailers. The pintle hook allows a connection to combination dollies from double/triple semi configurations, and the kingpin adapter enables rear picks on bobtail semi tractors when used with fork holders in the recommended position.

Pintle Kit
The Pintle Kit for Zip's HD Underreach Towing System includes the main underlift adapter as well as all as the pintle attachment and four mounting bolts. Bolted to the front of the adapter, this attachment allows heavy-duty tow operators to recover semi trailers with pintle hooks, such as double/triple combinations common to the LTL and foodservice industries. When using the pintle hook attachment, do not exceed the maximum gross trailer weight of 30,000 lbs. or the maximum vertical weight rating of 6,000 lbs.

Kingpin Kit
The Kingpin Kit for Zip's HD Underreach Towing System includes the main underlift adapter as well as all the powder-coated kingpin attachment. Pinned to the top of the adapter, this attachment allows heavy-duty operators to safely tow a bobtail semi from the rear.

To complete the hookup, the towing adapter and fork receivers first need to be rotated a quarter turn on the underreach's crossbar. The kingpin attachment is then inserted between the two supports and held in place with a 2" zinc-plated locking pin.

At this point, the kingpin should be facing the ground. The underreach is then lifted high enough to clear the tractor's frame, allowing the kingpin to slide into the fifth wheel. Prior to towing, the assembly should be secured to the frame with tie-down chains to the crossbar's endcaps with welded grab hooks. The fifth wheel jaws should also be locked around the kingpin attachment.

Fifth Wheel Kit
The Fifth Wheel Kit for Zip's HD Underreach Towing System includes the main underlift adapter as well as the fifth wheel attachment. This powder-coated attachment is pinned to the top of the adapter with a locking pin, and once hooked to the trailer, another 1-3/8" zinc-plated pin holds the kingpin in place.

This attachment works great for pulling campers, flatbeds, livestock and other recreational trailers with kingpins. This adapter can also be used to tow 53' semi trailers, but due to excess weight considerations, the trailer should be empty. Also, due to the 14" diameter of the fifth-wheel plate, please exercise caution when pulling this high-profile unit, especially with strong crosswinds. For comparison, a semi's fifth wheel plate is typically 35" wide.

Gooseneck Kit
The Gooseneck Kit for Zip's HD Underreach Towing System includes the main underlift adapter as well as all the gooseneck bracket and 2-5/16" ball. This powder-coated attachment bolts to the same four holes as the pintle hook attachment and offers a rated towing capacity of 20,000 lbs.
