Description
Snap-On / John Bean Quick Release Wing Nut with Pressure Cup – 40MM Wheel Balancer Shaft
The quick release wing nut speeds up the wheel balancing process by allowing the cone and wheel to slide in and out of position when the release lever is pressed, rather than threading on and off with each wheel change. When the wing nut or pressure cup wears out or becomes difficult to operate, replacing this assembly restores fast, efficient wheel changes on your balancer. This kit includes the quick release wing nut, a small pressure ring, and a large pressure cup for 40MM shaft balancers.
