Founders Performance 23962R-PHR On Car Adjustable Lower Control Arms & Panhard Bar Kit Rod/Rod Red - Car Set Replace those weak, factory stamped lower control arms with Founders Performance extreme duty tubular on car adjustable arms. These are a direct bolt-on replacement that minimize wheel hop, improve cornering, lowers Elapsed Time and greatly help your track consistency. The chrome-moly heat treated spherical rod ends allow your rear suspension to be bind free which makes these a great upgrade for both your track and auto cross driven car. Founders Performance control arms are constructed from U.S. made DOM steel tubing 1.250" OD x 0.095" wall, 1045 steel threaded tube adaptors (stronger than chrome-moly), completely CNC machined and fully pulse welded for outstanding strength.
