## Overview

The CURT 40047 RockerBall Cushion Hitch Trailer Ball supports up to 7,500 lbs towing capacity with a 2-inch diameter ball and 1-inch shank. Featuring patented ShockDrop technology, it cushions jerks and vibrations at the hitch point, delivering a quieter, smoother towing experience. Constructed from forged carbon steel with a corrosion-resistant chrome finish, it fits standard ball mounts and requires minimal maintenance via a grease zerk fitting. Ideal for professionals seeking enhanced control, durability, and comfort on every haul.

## Description

The CURT RockerBall trailer ball is a cushion hitch ball that dynamically absorbs jerking and jarring from your trailer at the coupling point. Just bolt it onto your existing trailer hitch ball mount to enjoy increased comfort, enhanced control and extended longevity of your vehicle's systems. 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-inch wide trailer ball tongue and 1-inch 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.

Review: Finally Quiet! - Oh the savior to the annoying rattling and clanking sound coming from your hitch while accelerating or braking. This has been in use for hauling my Runaway camper and has saved countless hours of having to turn the radio up. It should be noted that I use it in conjunction with a Quiet Ride Locking Tightening Hitch Pin which had solved part of the problem but not all on its own. The combination has been the answer to the problem and even results in a smoother ride. Well worth the money- I own two different sizes for differing trailer demands. Pros: Quiet, Sturdy, Offers a bit of slack absorption in comparison to a trailer catching up to the tow vehicle. Cons: Pricey comparing to swapping out ball sizes for your different needs, Keeping it properly aligned as to not rotate while tightening the nut is a challenge, the bottom is recessed with a grease fitting- if you ever drag your hitch it tends to fill with dirt- see pic.
Review: So far so good - Bit pricy for what it is but it does seem to work well. We'll see how it holds up long term. It does add about an inch of height so if you have you ball mount dialed in, this will mess up your trailer height a bit.

### ⭐⭐⭐⭐⭐ Curt Rockerball New Hitch design
*by B***. on April 28, 2021*

I purchased this 2 inch hitch ball to use with my New R-Pod Travel trailer we purchased last summer. Looked at the reviews about this hitch and wanted to check it out. The hitch seems well built. It has a shock absorbing feature, which is useful when towing a Travel Trailer down the road. The price point maybe a little higher than typical hitches but will pay for itself in smoother towing. Good product, and will prevent the jerks and usual tugging that comes with towing, and a good safety feature for a reasonable price.
