JBA Offroad manufacturers upper control arms (also known as UCAs or upper a-arms) for the Ram 1500 beginning with 2009 model year. With the right modifications, Ram 1500 models are wonderfully capable off-road vehicles.
All Ram 1500 models have independent front suspension and require replacement of factory upper control arms when lifted beyound 3". If factory UCAs are not replaced, your Ram 1500 alignment and clearances can be incorrect.
When Ram 1500s are lifted, caster is lost from the front-end alignment. Caster is critical for stability over 80km per hour and returns the steering wheel to center after going around a corner. Additionally, factory upper control arms often rub on the front springs at certain articulations.
JBA led the industry back in 2004 with the development of the first aftermarket upper control arms, which enabled the vehicles with independent front suspension to be safely lifted. Today, JBA upper control arms are installed on thousands of vehicles, including lifted Ram 1500s, and driven all over the world. JBA UCAs work with Ram 1500 lift kits up to 4 inches above factory ride height.
The JBA A-arms now come with JBA's own EZ Lube bushings! JBA 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.
