• Pushrod seat is made of a special powdered metal iron alloy that is heat-treated for strength & wear resistance

• Longer piston than conventional hydraulic lifters, which provides more load bearing surface & increases lifter longevity

• Lightweight check valve disc allows for quicker response, which results in increased engine speed before valve float

• Lightweight check valve disc maintains added control at all engine speeds & loads
