A schakle is an integral component of the suspension system that attaches between the leaf spring and the vehicle frame
Schakles are U-shaped pieces of metal secured with a pin or bolt across the opening, or hinged metal loops that are secured with a quick-release locking mechanism. They are made of different materials, including carbon steel, alloy steel, and stainless steel
It allows for the leaf spring to work through length changes during suspension articulation. The schakles are connected through the eye spring bolt and can be a very inexpensive way to lift a jeep or truck They also support the vehicle’s weight, since these are a primary component of the suspension system. As a leaf spring flexes up or down, its length from main eye to schakle eye changes
