Black Polyurethane Axle Pivot Bushings.
Replace those original equipment rubber bushings that deteriorate fast with any use.
Polyurethane bushings will last up to 3 times longer than original and perform better under the stresses of off-road punishment.
Durometer (the measure of softness) and tensile strength are some of the terms automotive engineers use to describe properties of elastomeric suspension components.
Automotive applications should vary in durometer between 65(soft) and 88(firm).
Performance, heavy duty and off road tensile strength should not be less than 2000-2500 psi.
With most polyurethane companies it ends up being the lower durometer, the lower the tensile strength.
Custom compounds and in-house proprietary formulations, engineers can now custom tailor the urethane properties in polyurethane products to provide the proper mix of strength and durometer as required by application.
RIDES BETTER, LASTS LONGER!
The suspension components abused by heavy off-road use, require good control.
In these off road applications, engineers specify a durometer of 80-85 to ensure good control.
Tensile strengths are achieved on the order of 5000 psi! to assure durability and long component life.
