The RockerBall tow ball is engineered with ShockDrop technology: a cushion isolator that reduces noise, vibrations and chucking at the coupling point. This produces quieter towing, increased driver control over the trailer and reduced strain on the vehicle's brakes, towing system and suspension, compared to a conventional metal-on-metal towing connection. The RockerBall fits onto a variety of standard ball mounts -- virtually any ball mount with a 2-1\/2 wide trailer ball tongue and 1 diameter ball hole. RockerBall is also virtually maintenance-free. Unlike other cushion hitch and torsion hitch options, it has no airbags or bearings to service. Just apply grease to the zerk fitting as needed for continuous lubrication and smooth towing. The RockerBall trailer ball is constructed from forged steel for exceptional strength, and it comes with a powder coat finish and chrome plating for dependable corrosion resistance.\u003c\/span\u003e\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 2-1\/2\" wide ball mount tongues with 1\" 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\" couplers\u003c\/li\u003e\n\u003cli\u003eRated for 7,500 lbs. gross trailer weight\u003c\/li\u003e\n\u003cli\u003eTested for safety to meet SAE J684 specifications\u003c\/li\u003e\n\u003cli\u003e\u003cdiv\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.\u003c\/div\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cdiv\u003eBall mount sold separately (not compatible with Rebellion XD ball mount)\u003c\/div\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cdiv\u003eLimited lifetime warranty (one-year finish, one-year parts)\u003c\/div\u003e\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Curt","offers":[{"title":"Default Title","offer_id":51914352590980,"sku":"CUR40047","price":52.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1009\/3199\/3732\/files\/orig_39-155638.jpg?v=1780438439","url":"https:\/\/unchartedusa.com\/products\/curt-rockerball-2-cushion-hitch-trailer-ball-1-shank-7500-lbs-40047","provider":"Uncharted USA","version":"1.0","type":"link"}
