  • 1x Kryptonite Alignment Pins Part# KR86326
    • ​These pins replace the alignment pins in the GM vehicles listed. The pins make it easier to align the vehicle and often become bent or crushed and need to be replaced. This kit includes 8 pins.

Note: These control arms work best on leveled or cranked torsion key applications.

Installation note: Mount upper ball joints using supplied 5/16” bolts, flat washers, and locknuts. Mount the ball joint to
the bottom of the control arm if your truck is adjusted above stock height. Mount the ball joint down through the
top of the control arm if your truck is stock height, or if you have a 4” and up lift kit and are keeping torsion keys
relaxed and control arm is flat.
