Boost Valve Kit Sonnax (Large Ratio) 4L30E ML4

Boost Valve Kit for 4L30-E Large Ratio, OE Code 264 In GM 4L30-E the original equipment (OE) boost valves are crafted from steel, while the sleeves are manufactured from aluminum. As these components interact over time, the valve experiences wear against the sleeve, leading to a leakage of boost pressure. This leakage subsequently results in a low line pressure during the boost phase, which is often accompanied by burnt clutches. The Sonnax boost valve kit 54200-06K is engineered to restore optimal pressure control within the boost circuit. The sleeve is constructed from wear-resistant aluminum and is designed with annular oil passages. These passages facilitate the even distribution of boost oil to the valve, thereby minimizing side loading. The valve, made of hardcoat anodized aluminum, is designed to resist premature wear effectively. The valve is equipped with oil grooves, allowing it to operate smoothly on a film of oil and further reducing wear. To minimize leakage resulting from thermal expansion, both the valve and sleeve are manufactured from the same material. The Drop-in Zip Valve™ components are designed for swift and simple installation. Note This kit is configured for a large boost ratio. Sonnax Part No. Boost Ratio Sonnax I.D. Mark OE/Euro I.D.
