You can have mine. Waste of money and dangerous. Not bad without a load. But with the 5th wheel hooked up, if I got in something slippery while accelerating from a stop (painted crosswalk, bit of sand, gutter in the road with a splash of water) and the tire spun - there was unbelievable (dangerous) wheel hop which shook the truck and trailer violently. Didn't need to be accelerating very hard or aggressively as this product kept the wheel from staying planted, inducing violent wheel hop. I put the factory shackles back on and have not experienced this since.
