Description

When your F-Body or GTO T56 build needs a bellhousing you can trust, don't settle for cheap knockoffs. This is the genuine TREMEC aluminum bellhousing - the same unit that came factory-installed on LS1-powered 1998-2002 Camaro and Firebird models, as well as the 2004-2006 Pontiac GTO. Factory machining ensures proper transmission alignment, starter positioning, and clutch clearance for a direct bolt-on installation with no modifications required.

Cast from lightweight aluminum at approximately 8.1 lbs, this bellhousing delivers the perfect interface between your LS engine and T56 transmission. It fits all GM T56 transmissions from F-Body and GTO applications, plus the aftermarket T56 Magnum. Whether you're restoring an F-Body to stock condition, building an LS swap, or upgrading to a Magnum, this is the bellhousing that thousands of LS/T56 combinations have depended on for reliable, factory-spec performance.

This bellhousing also fits Gen V LT engines, though note that the top bolt location will not be utilized in LT applications. Cross-referenced as GM part number 12453263 and TREMEC 1386-212-005 (also 92142856). When you need OE engineering with a proven track record, accept no substitutes.
