Features

• Maintains maximum valve lift; increases stiffness and column rigidity
• Maximizes valve-train stability to increase engine rpm, horsepower and torque output
• Minimal adjustment parameter eliminates flex and loss of valve-train stability problems
• Individual length intake and exhaust pushrods keep the adjustment extension to a minimum
• Designed to exceed performance engine needs using larger lift cams and high spring pressures while maintaining proper and critical oil flow to top-end valve gear
• Made from CNC-machined 7/16" tapered 4130 chromoly steel tube; 32 thread per-inch adjustment
• Double jam nut lock system
• Can be used with hydraulic or solid lifters and street or race engines; "Race" Series recommended when extreme spring pressures are used
• Fueling pushrods can be used with factory pushrod tubes
• Made in the U.S.A.
• Require removal of rocker covers and rocker arm supports.
