A new airbag is recommend
every 100,000 miles or 10 years.
1-Year Manufacturer Warranty

Note
If your airbag hitch is left outside on your tow vehicle or trailer year round, replace every 5-7 years.
Stop destroying your trailer and cargo.
Every bump, pothole, and expansion joint sends a violent jolt through your trailer frame, damaging cargo and wearing out your truck. Shocker Air Ride Hitches absorb that punishment at the coupling, before it reaches your trailer.
When the air bag in your gooseneck hitch wears out, the smooth ride goes with it. The chucking on rough highway comes back, and every hard stop hits like it used to, hammering your truck, your trailer, and whatever you're hauling. This is the replacement air spring bag (formerly part # 58740) that puts the cushion back. It drops straight into your Gooseneck Surge Air Hitch and gets the air ride doing its job again, soaking up the road shock so towing stays smooth and safe. An air spring is a wear part: plan to swap it every 100,000 miles or 10 years, and every 5 to 7 years if your hitch lives outside on the truck or trailer year round. We stock it in Canada and ship it direct, so there's no border wait.
Key Highlights
- Includes the air spring bag and air tank valve, the parts that put the cushion back in your air ride
- Drops straight into the Gooseneck Surge Air Hitch and Quick Air Gooseneck hitches
- Plan on a fresh air bag every 100,000 miles or 10 years to keep the ride smooth

What It Fits
- Drops into your Gooseneck Surge Air Hitch or Quick Air Gooseneck hitch
What You Get
You get the replacement air spring bag and air tank valve, the working parts of your air ride. Plan on a fresh bag every 100,000 miles or 10 years to keep the ride smooth. If your hitch stays outside on the tow vehicle or trailer year round, count on every 5 to 7 years instead.
When to Replace the Air Bag
The air spring bag is a wear part. If your Shocker hitch bleeds down pressure overnight, leaks where you can see it, or the bag has cracked with age, this is the part that brings the ride back. The swap runs about 5 minutes and takes no special tools.
