Description
Swapping a modern TREMEC five-speed into your classic GM muscle car or hot rod starts with the right bellhousing. This Lakewood cast aluminum bellhousing bridges the gap between small block and big block Chevrolet engines and transmissions using the standard GM Muncie bolt pattern-including the TREMEC TKO and TKX. For builders running hard at the track, the SFI 6.1 certification satisfies tech inspectors and sanctioning-body requirements for cars dipping into the 11.49-or-faster zone.
The 9:00 fork opening positions the clutch release arm for compatibility with traditional mechanical Z-bar linkage and external hydraulic slave cylinder setups. At 6.45 inches deep, the bellhousing maintains correct geometry for proper throwout bearing travel and clutch engagement. The cast aluminum construction shaves weight compared to heavier stamped-steel alternatives while ensuring precise register bore alignment-critical for smooth shifting and long component life.
Designed for 1958-1987 GM cars equipped with small block or big block Chevrolet V8s, this bellhousing accepts both 153-tooth and 168-tooth flywheel configurations. Whether you're upgrading from a tired Muncie four-speed, swapping out a Saginaw or T10, or installing a fresh TREMEC TKO or TKX five-speed, the shared bolt pattern makes this bellhousing a direct bolt-in solution. Built in the USA to Lakewood's exacting standards.
