None of the five listed torsion axles is rated for 5,000 pounds. The highest stated capacity is 3,500 pounds, so these options should not be treated as 5,000-pound replacements. The 3,500-pound Knott axles are best for boat trailers that match their specified dimensions; the 2,200-pound Triton axle suits a compatible snowmobile trailer, while the 2,000-pound stub axles suit certain custom installations. Confirm the trailer’s required capacity and measurements before choosing.
| Product | Stated capacity | Best suited for |
|---|---|---|
| Knott axle, 94-inch hubface | 3,500 lb | Boat trailers needing this width |
| Knott axle, 86-inch hubface | 3,500 lb | Boat trailers needing this width |
| Triton galvanized axle | 2,200 lb | Compatible snowmobile trailers |
| Knott jetski axle | 1,500 lb | Narrow jetski and boat trailers |
| RIGID HITCH stub axles | 2,000 lb total | Custom frame installations |
Knott 3,500-Pound Axle, 94-Inch Hubface
This galvanized Knott torsion axle is the highest-capacity option in this selection, rated at 3,500 pounds. It has a 94-inch hubface measurement, an 88-inch brake flange measurement, and an 82.5-inch measurement across the outside of the torsion brackets.
Best for: Boat-trailer owners whose replacement axle requires these measurements and a capacity no greater than the axle’s rating. It was selected because it offers the greatest stated capacity here and provides several fit dimensions for comparison.
Limitation: It is not a 5,000-pound axle. Do not use it as a substitute where the trailer requires that capacity.
Knott 3,500-Pound Axle, 86-Inch Hubface
This galvanized Knott boat-trailer axle is also rated at 3,500 pounds, but it has a narrower 86-inch hubface. The listed brake flange measurement is 80 inches, and the outside torsion-bracket measurement is 74.5 inches.
Best for: Boat-trailer owners who need the 86-inch hubface and matching bracket and brake-flange dimensions. Choose this over the 94-inch version when the trailer’s measurements call for the narrower axle.
Limitation: Its 3,500-pound rating is below the 5,000-pound capacity implied by the search. Verify that the rating is appropriate for the trailer’s load.
Triton 2,200-Pound Snowmobile Axle
The Triton 02360-G is a galvanized torsion axle listed for snowmobile trailers with a 2,200-pound capacity. The supplied product information does not provide hubface, bracket, or starting-angle measurements.
Best for: Owners replacing an axle on a compatible Triton snowmobile trailer who can confirm that the part and measurements match. It was selected for its clearly identified trailer use and stated load rating.
Limitation: The available details do not establish fit dimensions, and the 2,200-pound rating is not suitable for a 5,000-pound requirement.
Knott 1,500-Pound Jetski Axle
This galvanized Knott axle is rated at 1,500 pounds and has a 53-inch hubface, a 46-inch outside bracket measurement, and a 30-degree downward starting angle. The product name identifies it for jetski and boat trailers.
Best for: A smaller trailer whose required capacity and dimensions match the listed specifications. The narrow hubface makes it a distinct option compared with the wider 3,500-pound boat-trailer axles.
Limitation: Its 1,500-pound rating makes it unsuitable for a 5,000-pound application.
RIGID HITCH 2,000-Pound Stub Axles
This set of torsional stub axles is rated for 2,000 pounds total, or 1,000 pounds per stub axle. The axles can be bolted to a trailer frame or welded; mounting hardware is not included. The listed starting angle is 45 degrees downward, with 2.5 inches of travel.
Best for: A custom trailer-frame installation where the builder needs separate stub axles rather than a complete axle assembly. It was selected for its stated mounting options and suspension details.
Limitation: Installation hardware is not included, and the total stated capacity is not 5,000 pounds.
Buying Guide: How to Choose a Torsion Axle
What capacity should the axle have?
Match the axle rating to the trailer manufacturer’s requirements and the load the trailer must carry. Do not assume that a product’s title or fit dimensions establish a 5,000-pound rating. In this selection, the highest stated rating is 3,500 pounds. If your trailer requires 5,000 pounds, look for an axle explicitly rated for that capacity.
Which measurements should you compare?
Check hubface, brake-flange, and torsion-bracket measurements against the existing axle or trailer specifications. Hubface width alone does not establish a match. The two 3,500-pound Knott axles differ in hubface width by eight inches and also have different listed brake-flange and bracket measurements.
Does starting angle matter?
Starting angle affects the axle’s installed orientation and suspension position. Compare the required angle with the product specification before ordering. The jetski axle lists a 30-degree downward starting angle; the RIGID HITCH stub axles list 45 degrees downward.
Should you choose stub axles or a complete axle?
Stub axles can suit a custom frame, but their mounting requires appropriate hardware or welding. A complete axle may be a better fit for a direct replacement when its dimensions and capacity match the trailer. Confirm installation requirements before purchase.

No. The highest stated capacity among these products is 3,500 pounds.
Can I use a 3,500-pound axle on a trailer rated for 5,000 pounds?
Do not assume it is suitable. Follow the trailer manufacturer’s capacity requirements and use an axle with an adequate stated rating.
Are the 94-inch and 86-inch Knott axles interchangeable?
Not necessarily. They have different hubface, brake-flange, and bracket measurements. Compare all required dimensions before selecting one.
What does hubface measurement mean?
It is a key axle-width measurement used to compare replacement fit. Check it against the trailer or existing axle specifications, along with other mounting dimensions.
Does the RIGID HITCH set include mounting hardware?
No. The listed product information says mounting hardware is not included.
