Benefits of 22226-2B401 TAPPET VALVE
Choosing this specific mechanical tappet is vital for the long-term health of your engine’s camshaft and valves. Because Gamma engines utilize a shimless bucket design, selecting a premium lifter prevents “valve ticking” noise and ensures the engine maintains correct compression across all cylinders. Proper engine lubrication is key; therefore, we strongly recommend browsing our Fully Synthetic Oils to maintain the structural integrity of the tappet’s contact surface.
Check Engine Fitment Verification
Gamma engine tappets come in specific thickness grades (thickness codes) to match your engine’s wear profile. To ensure the 22226-2B401 TAPPET VALVE is the exact size required for your cylinder head, please contact us for professional verification using your chassis number.
