An integrated cushion isolator allows this hitch ball to turn a standard ball mount into a cushion hitch with anti-rattle capabilities. The RockerBallâ„¢ trailer ball dynamically reduces jerking and jarring while towing. As your trailer passes over bumps and potholes, it produces all kinds of vibrations, jolting, chucking and noise. With a traditional metal-on-metal connection, these annoyances are directly transferred to your tow vehicle, making your ride noisy, uncomfortable and taking a toll on your towing system. The RockerBallâ„¢ completely changes your towing experience by absorbing the erratic movement and rattling of your trailer at the coupling point. This provides a smoother ride and increased control over the vehicle and trailer. It also reduces the amount stress placed on your vehicle, receiver hitch, brakes and suspension system. The RockerBallâ„¢ is also extremely low maintenance compared to other torsion hitch and cushion hitch options. It has no airbags or bearings to service. Simply apply grease to the integrated zerk fitting as needed for continuous lubrication and smooth operation. The RockerBallâ„¢ tow ball retrofits onto a variety of standard ball mounts, virtually any mount with a 3-inch wide trailer ball tongue platform and a 1-1\/4-inch trailer ball hole. The anti-swivel base keeps the hitch ball properly oriented and locked in place when fully torqued. The CURT RockerBallâ„¢ hitch ball is constructed from forged steel for exceptional strength. The base is covered in a durable powder coat finish, and the ball itself has a chrome plating for long-lasting weather resistance.\u003c\/p\u003e\u003chr\u003e\u003cul\u003e\n\u003cli\u003eDynamic trailer ball featuring ShockDrop technology\u003c\/li\u003e\n\u003cli\u003eDampens jerking and jarring from bumps and potholes for smoother towing\u003c\/li\u003e\n\u003cli\u003eCushioned isolators reduce rattling and vibration for a more comfortable ride\u003c\/li\u003e\n\u003cli\u003eReduces shock loads to the vehicle during sudden braking or acceleration\u003c\/li\u003e\n\u003cli\u003eMinimizes stress on tow vehicle's suspension and brakes for extended longevity\u003c\/li\u003e\n\u003cli\u003eRetrofits onto most existing ball mounts to improve current towing experience\u003c\/li\u003e\n\u003cli\u003eVirtually maintenance-free with no airbag or bearings to service\u003c\/li\u003e\n\u003cli\u003eGrease zerk fitting provides easy lubrication\u003c\/li\u003e\n\u003cli\u003eAnti-swivel base fits 3\" wide ball mount tongues with 1-1\/4\" diameter hole\u003c\/li\u003e\n\u003cli\u003eForged steel construction for dependable towing power\u003c\/li\u003e\n\u003cli\u003eDurable carbide black powder coat finish on base and chrome plating on ball\u003c\/li\u003e\n\u003cli\u003eStandard trailer ball diameter fits 2-5\/16\" couplers\u003c\/li\u003e\n\u003cli\u003eRated for 12,000 lbs. gross trailer weight\u003c\/li\u003e\n\u003cli\u003eTested for safety to meet SAE J684 specifications\u003c\/li\u003e\n\u003cli\u003eBall mount sold separately (not compatible with Rebellion XD ball mount)\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eThe mounting platform must be at least 3\/8\" thick and the hole size must not be more than 1\/16\" larger than in diameter than the threaded shank.\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eLimited lifetime warranty (one-year finish, one-year parts)\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Curt","offers":[{"title":"Default Title","offer_id":51914352394372,"sku":"CUR40249","price":70.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1009\/3199\/3732\/files\/orig_29-153232.jpg?v=1780438426","url":"https:\/\/unchartedusa.com\/products\/curt-rockerball-2-5-16cushion-hitch-ball-1-1-4-shank-12000-lbs-40249","provider":"Uncharted USA","version":"1.0","type":"link"}
