The OE accumulator pistons have two seal rings. The seal groove at the open end of the piston is a larger diameter, with the seal ring acting as a guide to prevent piston-to-bore contact. The seal groove at the closed end of the piston is a smaller diameter and the seal ring acts as a conventional seal. However, due to the smaller seal groove diameter, the piston will contact the bore when side-loaded resulting in scuffing, wear and leakage of clutch apply pressure.Each piston in the Sonnax accumulator piston kit 44894-01MK features two guide seal rings, one at each end of the piston to prevent piston-to-bore scuffing when side loaded. Additionally, the oil sealing ring location is relocated on the piston allowing it to run in an un-worn portion of the bore enabling bores with moderate scuffing to be salvaged. Manufactured from 6061 billet aluminum, these pistons will upgrade late model applications with plastic pistons to prevent transmission failure due to piston breakage.Dual-guide seals prevent piston-to-bore scuffingUpdated seal location allows use in scuffed boresPrevents transmission failure from broken plastic pistons  APPLICATIONSDodge Dakota, Durango 2000-2006 V8 4.7LRam 1500 2002-2006 V6 3.7L V8 4.7L 5.7LRam 2500 ST/SLT 2004-2006 V6 3.7LRam 2500 ST/SLT 2004-2011 V8 4.7L 5.7LRam 3500 ST/SLT 2004-2007 V8 4.7L 5.7LRam 3500 ST/SLT 2004-2006 V6 3.7LJeep Grand Cherokee, Laredo 1999-2000 V8 4.7LLiberty 2002-2004 V6 3.7L Parts ship daily from our distribution center.FREE SHIPPING on US Orders GOT QUESTIONS on your specific Year/Make/Model?
