This is a one piece product that bolts into your existing bolt holes where your king pin box is mounted currently. Simply unbolt your existing king pin box and install the RVGC-AIR in the same bolt holes. This product is rated at 24,000 lbs and a tongue weight rating of 6,000 lbs. A smooth ride for you and your cargo. A single high quality airbag does the job.  Buy Now! $1424

The RVGC-AIR is the air-ride adjustable model which gives you about 4″ of adjustment down by the coupler and most trailer manufacturers have adjustable whole patterns to allow you an extra 3″ of adjustment where it bolts to your 5th wheel. Which makes the total about 7″ of adjustment.

Bolt hole location and number of holes will vary depending on the configuration of your current pin box model. Picture shown may not be the exact model for your application. The number of holes, and size of holes are specific to the pin box model currently on your unit. Buy Now! $1424

The RVGC-AIR will fit 12″ and 12.5″ wide pin boxes with the following bolt patterns.

Fits LCI 1621, 0719, 1716, 1116, 0115. Also fits Fabex 500, 503, 520, 530, and 560.

If your current pinbox is 12.5″ wide you must use the included 1/4″ spacer plates. 

Note: Keeping the airbag protected from the elements such as sunlight will help extend the life of the rubber cushion.

Pulling a trailer with this coupler is like riding on a cloud. It absorbs up to 59% of the bumps, jolts and jars that make towing hard on you, hard on your cargo and hard on your equipment. Living Quarters horse trailers really need this to save bedroom cabinets. Simply swap it out with the coupler on your gooseneck now – and, Walla! Instant gratification. Trailers keep getting larger with more weight on your truck. You need a buffer between your truck and trailer. The CC 2 Cushion Coupler costs hundreds less than air-bag style couplers – and its maintenance-free. The remarkably smooth ride comes from a patented system that uses world famous Timbren cushions combined with other proprietary shock-dampening technology.

You don’t sacrifice strength for smooth towing. With a gross trailer weight rating of 24,000 pounds and 8,000 pounds maximum tongue weight, this cushion coupler will take you wherever you’re going in remarkable comfort. The rubber inside the tube works as a guide for up and down motion as well as dampening front to back vibration. Designed to apply trailer cushion at different tongue weights, Cushion Coupler will work with a loaded or empty trailer or anywhere in between.
