Sonnax offers a hardened steel sleeve that reinforces the input drum to prevent this failure. Sonnax input housing overrun sleeve kit 77733-51KA includes a custom manufactured overrun piston designed for use only with a stamped steel forward piston, eliminating the need to use aluminum forward pistons. For additional torque capacity, this kit can be used in conjunction with input housing forward sleeve kit \u003ca href=\"..\/i-30503063-input-housing-forward-sleeve-kit.html\"\u003e77733-52K\u003c\/a\u003e.\u003c\/p\u003e\n\n\u003cul\u003e\n\u003cli\u003eHigh-strength, chromoly steel sleeve increases input housing torque capacity by protecting the shaft and overrun piston areas\u003c\/li\u003e\n\u003cli\u003eCustom overrun piston works with steel forward piston\u003c\/li\u003e\n\u003cli\u003eUniversal design fits both early- and late-style units\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003c\/div\u003e\n\u003cdiv class=\"part-accordion cb spaced-vertical\"\u003e\n\u003cp\u003e\u003cstrong\u003e\u003clabel for=\"components-panel\"\u003eContents:\u003c\/label\u003e\u003c\/strong\u003e\u003c\/p\u003e\n\u003cdiv class=\"accordion-content\"\u003e\n\u003cul\u003e\n\u003cli\u003eOverrun Piston\u003c\/li\u003e\n\u003cli\u003eOverrun Reinforcement Sleeve\u003c\/li\u003e\n\u003cli\u003eOuter Overrun Piston Seal\u003c\/li\u003e\n\u003cli\u003eInner Overrun Piston Seal\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003e\u003cstrong\u003eWarning:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThis kit must be used with a '97-later stamped steel forward piston or the aluminum piston in Sonnax forward sleeve kit \u003ca href=\"..\/i-30503063-input-housing-forward-sleeve-kit.html\"\u003e77733-52K\u003c\/a\u003e.
