Sonnax Smart-Tech Input Housing Kits

Maximize Automatic Transmission Strength 

Input Housing Kits by Sonnax are built stronger for extending the reliability and durability of an automatic transmission. Engineered to allow more clutch packs for increased capacity while a stronger backing plate eliminates flexing to help protect clutch burnup. A reinforcement sleeve and treated housing will resist failure in stressed areas, all providing a more robust unit than OE for extended service.
