If you're looking to add a modern transmission to your project, you need a modern bellhousing. Enter one of Lakewood's new Bellhousing Kits, the LK4200K. Designed with Tremec's TKX and TKO 5-speeds in mind, the LK4200K allows you to connect them and most 4-speeds to a Chevrolet LS, Small-Block, or Big-Block engine with ease. Perfect for a new build, swap, or as an affordable replacement, this kit comes with a lightweight aluminum bellhousing, dust cover, and all hardware necessary to attach to both the engine and transmission. This Lakewood cast aluminum bellhousing connects a Chevrolet LS, Small Block, or Big Block engines to aTremec TKX or TKO transmissions (GM pattern). They are a lightweight cast aluminum design and are meant to be used with hydraulic release (throw-out) bearings only (we suggest Hays #82-102). Also included are a stamped dust cover, the necessary hardware kit in Grade 8 or 10.9 (Lakewood #50368), and a grommet for sealing off the hydraulic hose opening. *See LK4000K for the SBC/BBC > TKX/TKO/Muncie/Saginaw kit (mechanically actuated clutch). *See LK4100K for the SBC/BBC > T-56/Magnum kit. *See LK5100K for the Gen III/IV/V LS/LT > GM T-56/Magnum kit.
