ABSTRACT:
A spring loaded quick release pin and tubular receiver with a retainer pin configured to secure the quick release pin in a shackle, clevis, yoke or forked rod end. The receiver is welded to a shackle or cast with the shackle as a single body. One end of the quick release pin has aligned J slots that engage the retainer pin positioned in the receiver with a clockwise twist. The other end of the quick release pin has a cap and a spring loaded sleeve that biases the cross pin against outside of the second leg of the shackle. The spring bias keeps the short leg of the J slot engaged with the retaining pin. The quick release pin is removed with a push and counter clockwise twist. The invention includes a kit with a receiver, a bushing and a quick release pin for installing or retrofitting existing shackles.
