PROTHANE POLYURETHANE BUSHING

Why Use Urethane?
Production vehicles are built using rubber bushings in control arms, strut arms, leaf springs, body mounts, motor mounts, transmission mounts, sway bars and shocks. Additionally, rubber components can be found being used on coil spring pads, leaf spring pads and suspension bump stops. Not only are rubber components on the soft side to accommodate the typical car and truck buyer, they tend to deteriorate rapidly. This contributes to premature component failure, a "spongy" ride and less than ideal performance handling. Urethane can correct these conditions, while improving drivability
Polyurethane is a term used to describe a wide ranging family of elastomers (any compound exhibiting the characteristics of natural rubber; stretchy and elastic). Poly meaning "many" and "urethane" the classification of the chemical structure. Polyurethane or urethane for short, is used as a solid cast material (bushings, mounts and mount inserts) and can be as soft as a rubber band or as hard as plastic.
How Are Urethanes Rated?
There are approximately 20 categories in which urethanes are rated based on physical properties. The most common is hardness. Others include: abrasion resistance, compression set, tensile strength, tear strength; etc. Ratings are not affected by the color. Does Urethane Squeak? In a word, NO. Squeaking is caused by high frequency vibrations that can be heard rather than felt. It is usually caused by lack of lubrication, poor installation, incorrect part, or urethane that may be too hard for the application. In sway bar mount applications, most squeaking is the result of not cleaning the bar thoroughly prior to installation and failing to use our "squeak proof" Super Grease! Additionally, all of our dynamic application bushings feature grooves or splines designed to hold our grease (Included) providing even greater performance.
Will I Lose Ride Quality?
The original rubber bushing or mount was fairly soft which helped to attenuate noise and vibration that is generated by the tires and road surface. Increasing the hardness of the bushing either with harder rubber, urethane or even bronze, will allow more transmission of noise and vibrations. Some manufacturers formulate the hardness and design to reduce this effect. A softer urethane bushing allows the vehicle to perform better without the harshness, even over rubber components of the same hardness. The only change in ride quality is increased performance! Do I Need Special Tools To Install? No. Installing urethane components requires no special tools. However, if unique tools and equipment are required due to the type of vehicle, you will need them in order to do the job properly.
