Includes 8 synthetic elastomer a-arm bushings, 4 steel sleeves, 4 washers 14ga, 4 washers .16" to service a pair of JBA upper control arms.

JBA proprietary bushings! We have added grease ports to keep the outer face of the bushings lubricated. These bushings will not get extruded from the housing due to being over pressurized with too much grease. This change will increase the performance, durability and lifespan of the a-arm bushings.

The maintenance procedure is simple: Pump grease in them until you see grease come out between the washers and the bushing.  JBA EZ Lube Bushings!

Synthetic Elastomer.
What is it?...... And why is it important?

Synthetic Elastomer is a long-chained polymer with many urethane constituents. Over the years the formulation has evolved to yield stronger, yet softer compounds ideal for on and off-road applications. As the compound advanced to yield higher tensile strength, elasticity, and dynamic load capacity, JBA uses the bushing to help aid and tune suspension geometry and get rid of squeaky poly urethane bushings.
