When purchasing these arms, the package content includes:
8 synthetic elastomer a-arm bushings retaining washers
4 steel bushing sleeves

Installation Instructions
Made of heavy-duty tubing, red powder coat finish, with replaceable ball joints, 4 grease ports for JBA EZ lube bushings, and ball joint.
Note: Left and Right UCAs are not 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.
JBA offers a ball joint on their UCA's so what’s the Difference between JBA Ball Joint vs Uni-Ball?
Range of Motion
The Uni-Ball has 66 degrees total range of motion. The JBA Ball Joint, on the other hand, gives you 90 degrees range of motion. That is the widest range of motion that you will find on the market today! The increased range of motion you get from our JBA Ball Joints will allow you to tackle even the toughest off-road traveling in your Toyota 4Runner.
Use Case
The Uni-Ball was designed for offroad racing applications, these vehicles are disassembled and they replace worn parts on their vehicle after every race. In other words, the Uni-Ball is not designed for the everyday weekend warrior who uses their vehicle for regular transportation more than they go off-road. The open design of the Uni-Ball allows dust, dirt, salt, and other debris to enter the component and wear it out prematurely. The JBA Ball Joint, on the other hand, has a semi-sealed construction that keeps debris and the elements out, extending the life of the joint and allowing you to use it in your daily driven vehicle.
Maintenance
When performing maintenance on your off-road vehicle, you will have a much easier time working with a JBA Ball Joint. Why? Because with a Uni-Ball, you must remove the control arms, press out the Uni-Ball to remove it from the control arms, wash it out and re-lube by hand, then press it back into the control arms, then reinstall them onto the vehicle. But the JBA Ball Joint comes with a grease fitting to expedite maintenance.
