Why synthetic elastomer bushings?

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 they will not squeak like polyurethane bushings.


The Ball Joint Range of Motion:

Up travel is 40 degrees off the centerline of the ball joint.

Down travel is 50 degrees off the centerline.

Full range of motion is 90 degrees.

Cerakote clear to protect the ball joint.


JBA UCAs give you MORE!

  • More spring clearance is More suspension travel
  • More Caster
  • More articulation, See JBA vs Uniball 
  • More Traction on the trails
Every 3,000-5,000 miles: (at the interval of every oil change) Grease the ball joint with 3-4 pumps of lithium complex grease fortified with moly (molybdenum disulfide), grease the A-arm bushings with 1-3 pumps
