Description
This is a Lower Control Arm (A-Arm) Bushing Set (8) POLY for a MG TD, TF, MGA, MGB. They are very easy to install, much easier than your stock bushings. These bushings are graphite impregnated for long life and no squeak. This will be the last set that you have to install. Cross Ref.# Similar 280-485, Y889P
Below are the advantages of using a poly urethane bushing in your British Car over rubber and a Delron product.
High Load Bearing Capacity Polyurethane has a high load capacity in both tension and compression. Polyurethane may undergo a change in shape under a heavy load, but will return to its original shape. Unlike rubber which will deform and deteriorated. Or a Delron product which is so hard there is no give.
Flexibility Polyurethanes perform very well when used in high flex fatigue applications. Flexural properties can be isolated allowing for very good elongation and recovery properties. Unlike rubber which will degrade under high loads.
Abrasion & Impact Resistance For applications where severe wear prove challenging, polyurethanes are an ideal solution even at low temperatures.
Tear Resistance Polyurethanes possess high tear resistance along with high tensile properties.
Resistance to Water, Oil & Grease Polyurethane's material properties will remain stable (with minimal swelling) in water / oil / grease. Polyether compounds will last many years in subsea applications.
Wide Resiliency Range Resilience is generally a function of hardness. For shock-absorbing elastomer applications, low rebound compounds are usually used i.e. resilience range of 10-40%. For high frequency vibrations or where quick recovery is required, compounds in the 40-65% resilience are used. In general, toughness is enhanced by high resilience.
Performance in Harsh Environments Polyurethane is very resistant to temperature extremes, meaning harsh environmental conditions and many chemicals will not cause material degradation.
