Zip's King Pin Attachment

This powder-coated steel king pin attachment fits Zip's HD Underreach Towing Adapter and 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 king pin attachment is then inserted between the two supports and held in place with a 2" zinc-plated locking pin. Once installed, the king pin should be facing the ground. The underreach is then lifted high enough to clear the tractor's frame, allowing the king pin to slide into the fifth wheel. Prior to towing, secure the assembly to the frame with tie-down chains to the crossbar's endcaps and make sure the fifth wheel's jaws are locked around the king pin attachment.

This attachment provides heavy-duy operators with an alternative method for completing rear picks, increasing versatility and profitability for their fleet. The powder-coated finish and welded construction also ensures years of rust-free, dependable service.
