Therefore, if you increase the weight rating of the Axis axle, that has the stiffer rubber rods, it will result in the trailer having a much stiffer ride. Depending on how you may or may not load the trailer, that could cause potentially a structural problem.

On the other hand, if you increase the rating to 4400 or 4500 pounds with the Henschen softer rubber rods, you would be OK.

The Axis rubber rods are made from extruded rubber, 80 Duro, that has a set test of 10.084 to 10.324 percent. They have a modulus test of 3700 pounds.

The Henschen rubber rods are made from molded rubber, 70 Duro, and have a set test of 9.026 to 9.154 percent. They have a modulus test of 2800 pounds.

The lower the set test, the better, and the lower the modulus test, the better, both of which result in a softer ride.

Andy,

The axle that you purchased from me when I worked at Axis may contain different rubber cords than the one Zep is referring to. The lengths and durometer may vary. In order for a "test" to be fair and comprehensive - one must compare apples to apples.

No flames intended - but you may have only tested one Axis axle - thus it is unsafe to speak in generalities or make "all inclusive" statements.

Respectfully,
Henry
