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 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 center line of the ball joint.

Down travel is 50 degrees off center line.

Full range of motion is 90 degrees.

Cerakote clear to protect the ball joint.

 

Do not fit the Superlift 4" kit, will fit if modified to 6" or 8" lift.

Do not fit the Rough Country budget lift, it lifts the front end over 22.50" (see below)

Max lift on the WK/XK is 4”
18.50” center of wheel to underside of fender flare is stock ride height.
21.00” is a 2.5” lift kit
22.50” is a 4” lift kit
over 22.50" the JBA UCAs will not work, you will not get a good front end alignment 

Only good up to 4" of lift (23" center of wheel to underside of fender flare)

 

JBA UCAs give you MORE!

  • More spring clearance is More suspension travel
  • More Caster
  • More Articulation
  • More Traction on the trails

 

Specs:

STD A-arm tubing 5/32" wall and 1" diameter.

 

Installation time: 1-3 hours

 

UCA Maintenance:

We would recommend using a lithium-based grease, one pump of grease in each bushing. Three pumps of grease in the ball joints after the install and every 3000 to 5000 miles.
