CURT RockerBall ShockDrop Tow Ball Solution for your Vehicle

The CURT RockerBall™ (40047-85) is a revolutionary 50mm trailer ball that dynamically reduces jerking and jarring during transit. Featuring patented ShockDrop™ technology, this cushioned tow ball isolates the metal-on-metal connection, turning a standard ball mount into a performance cushion hitch for a smoother, quieter ride.

Key Features:

  • ShockDrop™ Technology: Integrated cushion isolator absorbs vibrations, jolting, and chucking.
  • High Capacity: Rated for 3,500kg Gross Trailer Weight (GTW) and 350kg Tongue Weight (TW).
  • Universal Retrofit: Easily fits onto most existing ball mounts with a 75mm wide tongue and 7/8" hole.
  • Low Maintenance: No airbags or bearings to service; includes a zerk fitting for easy lubrication.
  • Anti-Sway & Anti-Rattle: Provides enhanced control and reduces noise at the coupling point.
  • Safety Tested: Meets AS4177-2 and SAE J684 specifications for peace of mind.
  • Premium Finish: Durable Carbide Black Powder Coat for superior corrosion resistance.

Traditional tow balls transfer every bump and pothole directly to your vehicle's frame, causing discomfort and wear on your suspension. The RockerBall™ acts as a buffer, cushioning the impact and providing an "anti-wobble" effect. Its anti-swivel base ensures the ball stays aligned with the tongue, while the carbon steel construction provides the strength needed for heavy-duty 3.5-tonne towing.

Please Note: The ball mount is sold separately. This product is not compatible with the CURT Rebellion™ XD ball mount series.

Specifications:

  • Ball Diameter: 50mm
  • Shank Diameter: 7/8" (22.22mm)
  • Max Capacity: 3,500kg GTW / 350kg TW
  • Material: Carbon Steel
  • Finish: Carbide Black Powder Coat
  • Warranty: Limited Lifetime (One-year finish/parts)

Good product. What you see is what you get.
Color: 1-Navy Blue
Material feels sturdy and was a perfect fit compatible for my iPad. There's adequate grip and padding for a comfortable yet slim feel. Magnets hold it close and in one position when propping it up for watching landscape videos. Back is translucent as advertised. Solid product, put it on as i opened my new ipad for immediate protection. Perfectly safe blind buy if you're also getting that 'frequently bought together' suggestion from Amazon.

Bright & Pretty Hot Pink.
Color: Pitaya Red, Color: Pitaya Red
Very pretty and bright. It’s thick and great quality. Strong grip and doesn’t come off easily. Easy to clean when it gets dirty. It also has a nice backing. I prefer the transparent bright pink backing than the clear version. I love the strong magnetic for when I position it upwards. It can be positioned downwards too.

Very protective iPad case
Color: 1-Navy Blue
This MoKo iPad case is excellent! It fits perfectly and provides great protection without adding bulk. The navy blue color looks very sleek, and the translucent back shell is a nice touch. It’s super magnetic, with great padding. The smart cover works flawlessly with the auto wake/sleep feature, and the cutouts line up perfectly for Touch ID. Lightweight, durable, and a fantastic value!
