Master Rebuild Kit for Honda/Acura K-Series 6-Speed

The MFactory Master Rebuild Kit provides an essential solution for servicing 2005-2015 6-speed K-series transmissions, including models like the RSX, TSX, ITR, CTR, and Civic Si. The kit features high-performance carbon-material synchros, which offer improved engagement and heat resistance compared to standard factory replacements. It is engineered specifically for transmissions equipped with single-cone (1-piece) 5th and 6th gears. Compatibility covers a wide range of K20 and K24 engine configurations, including EP3, FN2, and FD2 chassis, as well as specific transmission codes like NSN4, PNN3, PNN4, and SPNM. Please verify your transmission's cone configuration before installation, as this kit is intended for single-cone setups only. Professional installation is recommended to ensure correct tolerance setup and long-term reliability of the transmission internals.
