JBA Upper Control Arms are assembled and ready to bolt into your vehicle!
Made of heavy-duty tubing, red powder coat finish, with replaceable ball joints, 4 grease ports for JBA EZ lube bushings, and ball joints.
Note: Left and Right UCAs are symmetrical.
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
- More Traction on the trails
