Powerflex Heritage front arm inner bush BMW E21 (1975-1978) (2 parts)

The products in the Heritage range are made from polyurethane. This is a specialized plastic that has been around for some thirty years. Advances have enabled this material to be endowed with special properties. Suspension parts are among the most highly stressed components on a car, and are subject to enormous stress.

Originally, these parts were made from rubber containing products that deteriorate with age. Eventually, the vehicle moves more and more, offering less and less control over suspension geometry.

The result is accelerated tire wear, braking instability and poor roadholding.

The products in the Heritage range are distinguished by their dark gray color, to maintain the standard look of the original rubber parts.

Powerflex therefore created the material to overcome these problems. They designed a polyurethane compound that makes it possible to manufacture parts 25% to 30% stiffer than the old rubber products, while retaining exactly the same noise-absorbing properties.
