Sportsman Steel Features

Tool Steel Lash Adjusters – CNC machined, heat treated alloy steel lash adjusters have been proven through years of abuse.
Centerless Ground Shafts – Precision ground and heat treated Tool Steel shaft provides years of durable service.
Optional Ball Adjuster – Has less friction than cup type adjusters. Makes rocker arm stronger by increasing the adjuster thread area and eliminates counterbore area.
Optional Needle Roller – Recommended for use with high lift, high spring pressure applications. Prevents the roller from stalling and skidding across the valve tip. Highly recommended when using .312” or smaller valve stems.
