Find a Dealer
Nobody plans for a flat trailer tire. But if you've ever dealt with one on the side of the road, you know how miserable the experience can be. Crawling around on the ground, fighting a clunky bottle jack, hoping nothing shifts while you work. It's slow and frustrating.
Andersen Hitches built the Single Axle Rapid Jack (S.A.R.J.) to fix that.
Why Changing a Trailer Tire Is Harder Than It Should Be
Changing a tire on your tow vehicle is one thing. Changing one on a trailer is a different problem entirely. Trailers sit low, they're heavy, and most people aren't carrying the right gear to handle it safely. Traditional scissor jacks and bottle jacks require careful placement, slow manual cranking, and a lot of patience you probably don't have when you're stuck roadside.
Single axle trailer owners have had it especially rough. There just hasn't been a purpose-built solution for quickly and safely lifting a single axle trailer tire off the ground. Until the S.A.R.J.
What Is the Andersen Single Axle Rapid Jack?
The S.A.R.J. is a trailer tire jack designed specifically for fast, safe roadside tire changes and maintenance. The way it works is straightforward: place the jack on the axle next to the wheel, drive forward, and the axle lifts the tire off the ground. That's it.
No cranking, no getting under the trailer, no fuss.

- 15" of lift from axle to ground
- Compatible with tires 33" or smaller

- Comes with a rubber pad for traction and stability
- Removable chock adds 6.5" of relief to the post jack
- $74.99 (part #3610)
The Built-In Chock Makes a Difference
Once a trailer is lifted, keeping it stable is just as important as getting it up in the first place. The S.A.R.J. includes a removable wheel chock that locks into the jack and holds everything secure while you swap the tire. Whether you're parked on a flat surface or an uneven shoulder, that added stability matters.
Not Just for Single Axle Trailers
Despite the name, the S.A.R.J. works with double and triple axle trailers too. It's called the Single Axle Rapid Jack because it lifts one axle at a time, not because it's limited to a certain trailer type. So even if you're towing a dual axle camper or a triple axle equipment trailer, this jack belongs in your kit.

The S.A.R.J. is the newest member of a lineup that Andersen has been building for years. If you're looking for more ways to be prepared on the road, here's what pairs well with it:
The Rapid Jack is the original version, built for tandem and multi-axle trailers. Instead of lifting from the axle, you drive the good tire onto the ramp to lift the flat tire off the ground. It's rated up to 30,000 lbs and has been a go-to for trailer owners for years.
The Quick Tire Change Kit bundles a jack with an extendable lug wrench, reversible sockets, a Tuff Chock, and a carrying bag. Everything you need for a roadside tire change, all in one place.
The Tuff Chock is a simple add-on that pairs with the S.A.R.J. for extra security while the trailer is lifted.
Who Needs a S.A.R.J.?
If you're towing any kind of trailer and you don't have a fast, reliable way to change a flat tire, the S.A.R.J. fills that gap. Cargo trailers, boat trailers, utility trailers, small campers -- if it rolls on a single axle, this jack was designed with your setup in mind. And at $74.99, it costs a lot less than the time and stress of dealing with a flat the hard way.
