Ultralast Polyurethane Wheels

Ultralast high performance polyurethane wheels

The Ultralast wheel possesses "off the chart" performance characteristics-
specifically in the areas of thermal retention and rollability.  Heat buildup in
polyurethane due to high loads or continuous duty applications is the most common 
cause for material breakdown over the life of the wheel.  Ultralast polyurethane operates
much cooler under load and at higher speeds compared to most other urethanes.
The result is a simply superior dynamic performance and a longer service life. 
93-94 Shore A Durometer
Wheels are equipped with precision ball bearings.
