Drag racing Powerglides® generate higher line pressure than the OE servo-piston metal seal ring was designed to withstand. With pressures over 200 PSI, the end gap of the OE seal leaks, causing a partial-apply condition in low gear that can result in higher drag, heat and wear of the high clutch. The Sonnax No Leak Powerglide® Dual O-Ring Servo Piston 28821-01K uses dual O-ring seals for superior, positive sealing. In applications with a distorted servo piston bore or case flex, O-rings will conform to the bore surface, a feature not possible with metal sealing rings. Another source of leakage is the servo pin thru bore. The Sonnax No Leak Powerglide Dual O-Ring Servo Piston 28821-01K yields a precise, slip fit with the servo pin to further improve performance.
- Designed for high pressure drag racing Powerglides®
- High quality billet aluminum construction
- Rubber O-Rings offer improved sealing over OE metal sealing rings

Motor Vehicles
WARNING: Motor vehicles contain fuel, oils and fluids, battery posts, terminals and related accessories which contain lead and lead compounds and other chemicals known to the State of California to cause cancer, birth defects and other reproductive harm. These chemicals are found in vehicles, vehicle parts and accessories, both new and as replacements. When being serviced, these vehicles generate used oil, waste fluids, grease, fumes and particulates, all known to the State of California to cause cancer, birth defects, and reproductive harm.
Tools:
WARNING: Some dust created by power sanding, sawing, grinding, drilling, and other construction activities contains chemicals known to the State of California to cause cancer and birth defects or other reproductive harm. Some examples of these chemicals are: lead from lead-based paints, crystalline silica from bricks and cement and other masonry products, and arsenic and chromium from chemically treated lumber. Your risk from exposure to these chemicals varies, depending on how often you do this type of work. To reduce your exposure, work in a well-ventilated area and with approved safety equipment, such as dust masks that are specially designed to filter out microscopic particles.
