Whiteline Bushings

Are available for our car's control arms...as well as other components! It's a special poly that isn't as *hard* as Energy Suspension and others. Here is the cataloge. I have made an enquiry to sales oulets in the US to obtain them for the front control arm.

POLYURETHANE BUSHING HISTORY
The use of polyurethane in automotive suspension bushings dates back to the early 1970s when race car enthusiasts looked
for improved handling and suspension performance without having to resort to solid pivot points and connections. Traditionally,
polyurethane bushings and mounts were made from very hard urethane compounds exceeding 100 on the durometer
scale; where rubber was much softer and measured less than 58 on the durometer scale. The main reason for the extreme
hardness was the use of low grade polyurethanes.
In order to achieve abrasion resistance, tearing and compression set, the polyurethane needed to be very hard.
The second reason for this hardness was how the component was designed and manufactured.
While high performance polyurethanes were available they were both very expensive and required complex machinery in order
to process, mix and cast the component. Few customers would pay for the added expense; especially when the automotive
performance aftermarket was selling products at a third of the cost.
One company believed that the market would soon grow weary of ultra hard bushings that were noisy on the road and offered
little improvement in handling.
After many years of extensive development and testing of materials that would offer strength and durability, geometry
retention and memory without the harshness, WHITELINE created a progressive, long-chain polymer compound incorporating
polyurethane constituents, which deliver the combined physical advantages of a solid bushing, with the extreme flexibility
characteristics of rubber.
Whiteline Plus polyurethanes provide the softness needed for low vibration, noise and harshness characteristics, while
displaying extreme abrasion, tear and cut resistance, and near-zero compression set at lower durometer reading of 70-80.
In addition, these performance polyurethanes allowed the polymer chains to be bonded directly to the metal shell, which
provided a method of flow control giving the bushing the characteristics of soft ride while on smooth roads, and when under
cornering pressure caused the bushing to become firmer for improved suspension performance.
The quality ride of rubber, the performance of solid links; offering the best of both worlds!
That range of product is known as WHITELINE ‘PLUS’.
Key Benefits of WHITELINE PLUS polyurethane bushings:
• The quality of ride of rubber, with the performance of solid links.
• Long lasting durability.
• Resistant to chemicals, oils and weathering.
• Enhanced handling, steering response and road holding stability.
• Increased braking capacities and positive brake pedal ‘feel’.
