CURT RockerBall 2" Cushion Hitch Trailer Ball — 1" Shank, 7,500 lb Capacity with ShockDrop Vibration Isolation

The CURT RockerBall 2" Cushion Hitch Trailer Ball with ShockDrop technology smooths tow-line shock and vibration at the coupler for quieter, more controlled towing.

Designed to replace a standard 2" trailer ball on any compatible ball mount, the RockerBall adds a cushioned isolator that absorbs sudden jerks, chatter and bounce at the hitch connection. 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.

How does the RockerBall reduce jolts and trailer chatter?

RockerBall 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.

• Elastomer cushion absorbs and disperses impact energy
• Reduces coupling-point noise and vibration
• Decreases quick, repetitive jarring during rough road conditions

Will the RockerBall fit my existing ball mount and hardware?

The 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. Installation is straightforward — unbolt your old ball and replace it with the RockerBall using the same pattern, ensuring proper torque on the shank nut and a secure fit.

• 1" shank diameter fits common 1" ball holes
• Compatible with 2" trailer ball couplers and standard mounts
• Includes grease zerk for periodic lubrication

What are the materials and maintenance requirements?

The tow ball's core is forged steel for high strength; exterior surfaces are finished with powder coat plus chrome plating to resist corrosion. Maintenance is minimal — the design avoids air bladders or bearings and only needs occasional grease via the zerk fitting to keep the isolator moving smoothly.

• Forged steel construction for long-term durability
• Powder coat and chrome for weather resistance
• Simple zerk fitting for periodic lubrication, no complex servicing

How does RockerBall affect vehicle wear and handling?

By moderating sudden impact loads at the hitch, the RockerBall reduces shock transmitted to the tow vehicle's suspension, frame and braking system. That can translate to steadier trailer tracking, less driver fatigue from continuous vibration, and potentially lower long-term stress on towing components.

• Lessens strain on suspension and braking components
• Promotes smoother trailer control and tracking
• Helps reduce noise and driver distraction while towing

Who is this for: The CURT RockerBall 2" Cushion Hitch is intended for drivers who use a 2" trailer ball and want a simple, rugged upgrade to reduce tow-line shock and noise without complex maintenance. It's suitable for owners of trucks, SUVs and vans who tow utility trailers, small campers or boats up to the 7,500 lb. rating and who prefer a bolt-on solution that fits standard ball mounts.
