Steering knuckle for 150s and 250s.  This is the older-style steering knuckle used on most karts before 2009.  This steering knuckle is NOT adjustable and measures roughly 11 inches from end to end.  

This steering knucle is used on most 150s without an adjustable steering rack.

Please check to see if your gokart uses the other steering knuckle (part # 6.000.093-250) before ordering.

Hammerhead part # 6.000.093
