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.
Your Shocker air hitch rides smooth because of one part doing the hard work: the air spring bag, sometimes called the air bag. It is what soaks up the jarring, the chucking, and the hard stops so they never reach your truck, your trailer, or your cargo. It is a wear part, though, and over the years it fades. When your hitch starts riding harsh again or will not hold air, this is the replacement (formerly part # 58124), sized for the TONGUE MOUNT on the Shocker HD Air Hitch, Air Tongue Mount Coupler, and Pintle Ring. Plan on a new air spring every 100,000 miles or 10 years. If your hitch lives outside on the tow vehicle or trailer year round, replace it every 5 to 7 years. Drop in a fresh bag and let the air ride go back to absorbing the road shock, so towing stays smoother and safer.

What It Fits
- Fits the HD 20K Air Bumper Hitch and Air Trailer Tongue Mounts
How Often to Replace It
The air spring is a wear part, so plan ahead instead of waiting for a rough ride. A fresh bag every 100,000 miles or 10 years keeps the air ride doing its job. If your hitch stays outside on the tow vehicle or trailer year round, the weather works it harder, so swap it every 5 to 7 years instead.
When to Replace the Air Bag
Not sure if yours is done? Watch for three things: it loses pressure overnight, it leaks where you can see it, or the bag is cracked from age. Any of those and this is the part you need. The swap takes about 5 minutes and no special tools, so you are back on the road the same afternoon.
