The bolt-on, six-hole mounting pattern fits common heavy-truck installations and the spring-loaded locking arm secures lunette eyes from 2-3\/8\" to 3\" I.D. The air-compensated design accepts an air chamber and plunger (sold separately) to cushion movement between hook and drawbar eye, reducing slack and improving stability during starts, stops and uneven terrain.\u003c\/p\u003e\n\n\u003ch3\u003eHow does the air compensation improve towing performance?\u003c\/h3\u003e\n\u003cp\u003eThe air chamber smooths the connection between the pintle hook and the drawbar eye, absorbing shock that would otherwise transfer to the hitch, trailer and vehicle.

The Buyers Products PH50 is aimed at fleet managers, contractors, municipal services, and heavy-haul operators who need a rugged, bolt-on hitch that tames slack and shock on heavy trailers. It’s well suited to semi-trailer use, pup trailers, and demanding off-highway tasks when used with appropriate drawbar hardware and adherence to load reductions off-road. Choose the PH50 when durability, controlled towing dynamics, and compatibility with standard lunette eye sizes are priorities.\u003c\/p\u003e\n\u003csection class=\"product-faq-snippet\"\u003e\u003ch3\u003eFAQ\u003c\/h3\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: Can the PH50 be used without the air plunger?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: Yes.
