Benefits of 22115-42000 GUIDE-EXHAUST VALVE

Choosing this specific exhaust valve guide is vital for preventing stem seizing and maintaining correct exhaust valve cooling. Because diesel exhaust reaches extreme temperatures, selecting a premium guide prevents stem play, which leads to premature wear of the valve stem seals and loss of compression. To ensure a professional cylinder head overhaul, we strongly recommend browsing our Exhaust Valves to ensure perfect stem clearance.

Check Engine Fitment Verification

The D4B diesel series requires exact tolerances for exhaust guide installation. To ensure the 22115-42000 GUIDE-EXHAUST VALVE is the correct specification for your specific cylinder head, please contact us for professional verification using your chassis number.
