My front shackles like that lasted 8 miles. Bought my second Pioneer and needed a front tow point. Added the eBay 3/4 shackle mounts with backer plates. Went out for the break in ride. Snapped a left front axle shaft at 6 miles and fought to get back to the truck with just 3 wheel drive. Ripped those shackles through the bumper. Wouldn't recommend them to any one. 2500 miles later that been the only broken shaft on Pioneer #2. And the stock bumper got pitched within the first year.
