Steering Stems work with Anti-Vibe Clamp to Reduce Rider Fatigue. All Houser steering stems are made from 4130-chromoly steel. Houser Racing steering stems are professionally welded to ensure high quality product that will hold up to the harshest conditions. The welded upper portion of Houser Racing steering stems over the wimpy casting is an industry standard. The Houser Steering Stems are backed by more then ten years of developing and testing ATV suspension and chassis components resulting in one of the most durable ATV steering stems available. Handle Bar Clamp is required and sold separately.
