At pressures over 200 psi, the OE piston can crack, resulting in transmission failure. Sonnax servo piston kit 28821-02K improves transmission performance and durability under high-pressure conditions. The piston can be assembled using only one seal ring for lower friction, two aluminum seal rings or any combination in between.\u003c\/p\u003e\n\n\u003cp\u003e \u003c\/p\u003e\n\n\u003cul\u003e\n\n\u003cli\u003eHigh-strength billet aluminum piston also features a rounded profile for better stress distribution\u003c\/li\u003e\n\n\u003cli\u003eDual PTFE seals improve sealing, are low-friction and interchangeable with the OE cast aluminum seal ring\u003c\/li\u003e\n\n\u003cli\u003eEasy to install, no case modifications required\u003c\/li\u003e\n\n\u003c\/ul\u003e\n\n\u003cp\u003e \u003c\/p\u003e\n\u003c\/div\u003e","brand":"Suncoast Performance","offers":[{"title":"Default Title","offer_id":48219394801905,"sku":"28821-02K","price":110.53,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0641\/1344\/3057\/files\/Servo-Piston-Kit-PTFE-Sealing-Ring-Style-Suncoast-Performance-151094439.jpg?v=1779829249","url":"https:\/\/tamelessperformance.com\/products\/suncoast-28821-02k-servo-piston-kit-ptfe-sealing-ring-style","provider":"TAMELESS PERFORMANCE","version":"1.0","type":"link"}
