Stop destroying your trailer and cargo.
Every bump, pothole, and expansion joint sends a violent jolt through your trailer frame, damaging cargo and wearing out your truck. Shocker Air Ride Hitches absorb that punishment at the coupling, before it reaches your trailer.
Got a metric-coupler trailer in Australia or Europe and no clean way to run it behind your Shocker bumper hitch? This attachment sorts it out. It's a Shocker ball mount built with a metric hole so you can bolt on your own metric hitch ball, made for Australia and Europe only, and set up for a "Tregg" or "Polyblock" style connection. The 22 mm hole (7/8″) takes a 50mm or 70mm bolt-on hitch ball so your coupler seats the way it should (hitch ball not included). Choose from standard, euro, off-road, drop and raised shapes to get the ride height and clearance your rig needs. It drops into Shocker Air, Streamline and HD series bumper hitches, XR series hitches and Impact series cushion hitches. Stocked in Canada and shipped direct, no border wait.
