Building a trailer ?
Couldn't be more simple using a Torflex (same principle as durotorque) complete axle assy - made in the USA.

Single axle with independent suspension.

Dexter Torflex Axles are the best selling axles in the USA.
The difference between towing a trailer with these axles and a leaf spring set up is remarkable. They are extremely quiet and provide a superior smooth ride using independant rubber suspension.
Superb if you have a lighter tow vehicle as the trailer won't cause the tow vehicle to bounce.

Measures 1800mm outside hub face to h/face.

Mount bracket centres 1415mm.

100% complete with 5 stud hubs (Toyota or Ford pattern)

Rated to 1585 KG

Provision to fit electric drum or hydraulic disc brakes.
Axle can be used as a crossmember.

If two units required for a tandem I will supply the second unit with 10% discount.

(I only have two of these axles in stock).

Price up Durotorques on their own - these are a bargain as a complete assy !
