The air bag assisted ShockerHitch, which slides into a 50 mm standard towbar receiver tube (e.g. Hayman Reece), utilizes the air bag to remove the unforgiving metal to metal connection between the tow vehicle and caravan/trailer/horse float. The geometry of the design centers around a solid pivot pin which allows a rocking motion cushioned by the air bag to smooth out the road produced shocks both up/down and forward/back. The air bag pressure is easily set to the drawbar weight of each piece of towed equipment, with a few steps on a foot pump, and the tow ball height is adjusted to suit, by moving the mount plate up or down through the range, with simple locking pins. Therefore, the ShockerHitch can be easily transferred from vehicle to vehicle and can adapt to any piece of equipment fitted with a towball coupling. Air Shockerhitch are towing Caravans, Horse floats, Boat trailers, Car trailers, Trade trailers, Farm trailers, Toy trailers etc. etc. and can be moved between tow vehicles and adjusted to suit trailer coupling heights in less than a minute.The engineering and manufacture of ShockerHitch products is second to none and incorporates a solid steel mounting bar and a grease able pivot pin. The hitches are rated to 12000 Lbs. which is well over the 4500 kg maximum tow ball rate in Australia. (3500 kg max. for 50 mm ball, 4500 kg max. for 70mm ball) a 2 ½” shaft option is available as is a conversion for late model US style trucks. Two soft bump bushes form a second line of defense against particularly heavy road bumps. A range of optional ball mounts includes raised and drop mounts for higher or lower applications. Development and improvement of the products is always ongoing. A standard ShockerHitch without an airbag is also available where polyurethane bump cushions absorb the destructive energy. The standard Shockerhitch is ideal for camper trailers, smaller single axle caravans and applications where the underside of the receiver tube on the tow vehicle is obstructed. Shockerhitch Australia now distributes the ShockerHitch, gooseneck, fifth wheel and heavy equipment trailer mounted cushion hitch models.ShockerHitch Australia offers a 2 year warranty and stock a full range of rarely sold spare parts in their Brisbane facility. While we can supply a ShockerHitch unit for the vast majority of tow rigs and can adapt for various trailer couplings like Pintle Hook, Bartlet Ball, Trig, McHitch etc. occasionally we find a tow rig where the geometry will not allow ShockerHitch to perform properly. In these cases we recommend alterations to the rig setup before we will supply a unit.
