img{max-width:100%} 4L30E Transmission Boost Valve Medium Ratio Sonnax 54200-01K AR25 AR35Medium Ratio, OE code 448In GM 4L30-E (AR25 and AR35) units the OE boost valves are made of steel, whereas the sleeves are made out of aluminum. Over time the valve wears against the sleeve and causes boost pressure leakage. The result is low line pressure during boost, with associated burnt clutches. Sonnax boost valve and sleeve kit 54200-01K restores pressure control to the boost circuit.Sleeve is made from wear-resistant aluminum and incorporates annular oil passages to distribute boost oil evenly to the valve and reduce side loadingValve is hardcoat anodized and includes oil grooves which allow the valve to ride on a film of oil, further reducing wearValve and sleeve are made from the same material to help reduce leakage due to thermal expansionNoteMedium boost ratio kit.¬†ContentsValveSleeveAPPLICATIONSAcura SLX 1996-1999 V6 3.2L 3.5LBMW 318i 1991-1999 L4 1.8L 1.9L323i 1997-1999 L6 2.5L325i 1992-1995 L6 2.5L328i 1996-1999 L6 2.8L525i 1991-1995 L6 2.5L528i 1996-1999 L6 2.8LZ3 Z3 Roadster 1996-2000 L4 1.9L L6 2.8LCadillac Catera 1997-2001 V6 3.0LIsuzu Amigo 1999-2000 V6 3.2LAxiom 2002-2006 V6 3.5LRodeo 1990-2006 L4 2.2L 2.6LRodeo 1990-2006 V6 3.1L 3.2L 3.5LTrooper 1992-2002 V6 3.2L 3.5LVehiCROSS 1999-2001 V6 3.5LHonda Passport 1994-2002 L4 2.6L V6 3.2LParts ship daily from our distribution center.
