Jeep Grand Cherokee WK1 Adjustable Rear control arms

Stock control arms use soft rubber bushing at the mounting points at the chassis and axle. Although a more comfortable riding experience for the average driver, rubber bushing has poor performance in terms of handling and traction.

Karma Racing Products uses Pro Krawler joints, the ultimate high strength heim joint, threaded into 4130 chromoly tube ends, all precisely TIG welded.  Karma Racing Products control arms are designed to withstand repeated hard launches and performance use for years.  Krawler joints are completely serviceable and rebuildable.

If your Jeep is lowered, having adjustable upper & lower control arms are particularly important.  The pinion angle needs to be adjusted when lowered, not only for more traction but also to increase longevity by maintaining proper wear and tear on the drivetrain.
