Built from forged steel with corrosion-resistant coatings, it installs to mounts with a 2-1\/2\" wide tongue and a 1\" ball hole and carries a 7,500 lb. towing capacity. Because it uses a simple greaseable zerk fitting rather than airbags or bearings, the unit delivers low maintenance performance for everyday towing needs.\u003c\/p\u003e\n\n\u003ch3\u003eHow does the RockerBall reduce jolts and trailer chatter?\u003c\/h3\u003e\n\u003cp\u003eRockerBall uses a built-in ShockDrop elastomer isolator that compresses and dampens impact forces transmitted between the tow vehicle and trailer. Instead of metal-on-metal transfers, the cushion smooths shocks from potholes, speedbumps and abrupt stops, lowering audible rattling and sudden tugging at the hitch.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eElastomer cushion absorbs and disperses impact energy\u003c\/li\u003e\n  \u003cli\u003eReduces coupling-point noise and vibration\u003c\/li\u003e\n  \u003cli\u003eDecreases quick, repetitive jarring during rough road conditions\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWill the RockerBall fit my existing ball mount and hardware?\u003c\/h3\u003e\n\u003cp\u003eThe RockerBall is designed to mount to most standard ball mounts that accept a 2-1\/2\" wide trailer ball tongue and a 1\" diameter ball stud.
