American-made steel tubing, red powder-coat finish, replaceable ball joints, 2 grease ports for the JBA EZ lube bushings, and 1 grease port for the ball joint.

Note: Left and Right UCAs are symmetrical. 

Every 3,000-5,000 miles: Grease the ball joint with lithium complex grease fortified with moly, until you see the boots swell (3-4pumps). Grease the arm bushings with the same grease until you see grease pushing out from the EZ Lube ports.
Product FAQs

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.

The Jeepin' By Al Upper A-Arms were designed for your lowered Grand Cherokee(WK)SRT8 and will directly replace your stock upper a-arms. The original upper control arm equipment is not designed to give a good front-end alignment, which causes premature tire failure on a Jeep with a lowering kit.
