Answers to your questions regarding Prothane suspension and motion control products
Why Use Polyurethane?
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.
What Is Polyurethane?
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.
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.
How Are Urethanes Colors Rated?
PROTHANE™ kits are stocked only in RED or BLACK polyurethane. (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 Need To Reuse My Metal Shells?
Why are there so many different sway bar bushing sizes for my application?
SWAY BAR BUSHING SIZE INFORMATION
Dont ask us why, but a certain year vehicle may have come from the factory with many different sized sway bars. There is no rhyme or reason to this practice.
The ONLY way to make sure your get the right sized bushings is to physically measure the sway bar before ordering.
As some sway bars on vehicles are offered with many sizes close together, we suggest using dial calipers or a micrometer to get the correct measurment as this will be most accurate.
Buying the correct size bushings is VITAL to ensuring optimum performance from your sway bar. Bushings that are too large will not properly grip and support the sway bar. Likewise bushings that are too small may simply not fit over the bar and make installation impossible.
Due to the following reasons we can be responsible for shipping or other costs associated with improper fitting sway bar bushings.
We have gone to great lengths to ensure the descriptions are correct for all Prothane parts, if you have any questions, please email email@example.com before ordering.
PROTHANE™ has a complete shell program for most popular applications. Many of the control arm bushing kits come complete with a new shell. On some applications you will need to reuse the metal shell, so be very very careful when removing it from the vehicle. The shells themselves are not a replacement item. If you do damage a shell during the removal procedure, you have a few choices: Obtain a used piece from a repair shop or salvage yard or purchase a new shell with rubber bushings from your local parts store.
