Galvanized Boat Trailer Dexter Torsion Axle w/ Accu-Lube Hubs 6000lbs 95" Hubface. Condition is "New".
This axle is designed specifically for 80" wide I beam boat trailer frames.
This 6000lb Capacity Galvanized Boat Trailer Torsion Axle from Dexter Axle is galvanized for corrosion resistance, and come with pre-installed with hot-dipped galvanized hubs and are common on many different brands of boat trailers. The "springless" suspension system uses four rubber chords surrounding the inner axle shaft to provide shock absorption at the appropriate levels based on the terrain and load spring, and will outlast traditional leaf spring suspension. Torsion Axles are mounted to the frame of boat trailers using U-bolts or bolts and can be affixed to I-Beam Frames, Tubing Frames, and C Channel frames. In most cases this axle would be used on an Aluminum I Beam Frame that previously had a torsion axle, and just needs a replacement.
Torsion Axle Specifications:
- Hubface measurement - 95"
- Brake flange measurement - 88"
- Outside of torsion bracket - 82-1/2"
- Starting angle height (no load) - 4.26"
- Starting angle height (full load) - 2.04"
- Torsion axle starting angle - 35 degree down
- 6 on 5 1/2" bolt pattern

- V Bend Style Torsion Axle with drain hole
- Grease-able spindle
- 4 Hole Brake Flanges for disc brakes
This Hot-Dipped Galvanized Torsion Axle ships with galvanized Idler hubs installed. The hubs and bearings are pre-greased with a lithium-based grease, but additional grease may be added after installation.
Galvanized Hub Specifications:
- 6 on 5 ½ inch Bolt Pattern
- 1-3/4 inch inner bearing, 1-1/4 inch outer bearing
- 2-1/4 inch inner diameter grease seal
- Hot-Dipped Galvanized
- 1.98 dust cap size, dust cap is included and has a removable rubber plug for easy access to the Spindles built-in Grease fitting.
If you need to replace the mounting hardware as well, either Click the Check Box for (4) I Beam Torsion Axle Mounting Bolts SS, or Go to 1/2 inch Diameter by 1 1/2 inch Long Stainless Steel Bolt and order the quantity you need (typically 4 total per axle.)
New Mounting Holes May need to be drilled in order to install the new axle.
These Axles can be used on Boat Trailers or Utility Trailers. Box Trailers, Car Haulers, Horse Trailers etc. can all benefit from the Torsion Arm System over leaf springs, and the Galvanized Coating will last even longer if the trailer isn't entering saltwater.

SELECTING THE PROPER TRAILER AXLE
When selecting an axle for your application remember to consider the following important specifications:
-
LOAD CAPACITY: the load rating of the axle must support the maximum gross vehicle weight rating. For multiple axle trailers divide the GVWR by the number of axles to determine the minimum load capacity of each axle.
-
TRACK LENGTH: measure your axle track length by determining the distance between the center of one tire to the center of the other tire. A more precise measurement can be made by measuring the distance from one 'HUB FACE' to the other. The hub face is also known as the mounting surface where the wheel studs are located.
-
SPRING CENTERS: measure the distance from the center of one spring to the center of the other.
NOTE: not required for replacement torsion axles
-
OVERALL LENGTH: measure the distance from the very end of an axle's spindle to the very end of the opposite spindle.
-
AXLE STYLE: important when reusing old mounting hardware and also for proper tire clearance. Includes straight axles (round or square), drop axles with offset spindles, and torsion axles. Also consider spindle size when reusing existing hubs or drums.
-
AXLE CAMBER: Most trailer axles are designed with a bend in the tube that will deflect when the load (weight of the trailer) is applied. This will theoretically bring the trailer wheel camber toward a 0 value that is the best setting for most trailer applications. This will allow the tires to wear evenly and allow the longest tread life. Camber can be affected by damage to the axle. For example, if the axle spindle is bent, this will usually cause a negative camber on that side which will cause excess tread wear on the inside of that tire.
How can I tell between a torsion axle and leaf spring axle?
If you have spring axle suspension your trailer will have leaf springs. Your suspension should look similar to this:
If you have torsion axle suspension your trailer will look similar to this:
What are the pros and cons of a leaf sprung axles and torsion axles?
Both torsion and suspensions have a record of reliability. There are advantages and disadvantages to both, but it comes down to your preference because they both work great in their own way.
Torsion axles are made up of thick rubber cords concealed in the axle's tubing. As each wheel moves up and down, the rubber cords compress offering an even wheel suspension for a smooth ride. Each wheel acts independently, moving and absorbing shocks.Torsion axles are mounted directly to the frame which means fewer moving parts compared to spring suspensions, resulting in a smoother shock action. This stiffens the frame, reducing flex.
This system is also less likely to corrode because the axle tube is galvanized inside and out. There are no metal-to-metal action like springs, so bare metal isn't exposed, preventing corrosion. There are fewer working parts in a torsion suspension, therefore less maintenance is required.
The disadvantages of torsion are they are more expensive than spring suspensions and more expensive to repair or replace. There is also no impact distribution, so if you hit a curb, the full impact is on one wheel or set of wheels.
Leaf springs have been used for centuries and have proven to be solid performers. This is the most widely used suspension system due to its affordability. Spring suspensions are the most dependable for even tire wear and a steady ride, especially in multi-axle applications. Leaf springs better absorb the load from uneven ground or shock from a pothole. Each tire has its own set of springs. If you have to store your trailer on uneven ground, the independent wheel suspension means the trailer will hold up better over time. Spring suspensions are cheaper and easier to repair compared to torsion suspensions.One con of springs is the metal-on-metal design can lead to faster wear, leading to more frequent repairs. Spring suspensions also tend to be a bouncy ride with an empty load or on uneven, rough roads.
