Bellhousing Chevy 168 Tooth to T56 SFI 6.1

The Quick Time RM-6023 Bellhousing is a purpose-built adapter designed to mate a Chevy 168-tooth flexplate with a T56 transmission in GM LS-Series engine swaps. This SFI 6.1-certified steel bellhousing delivers the structural integrity and compliance required for high-performance engine conversions, whether in street applications, track builds, or engine transplant projects. The 168-tooth configuration is standard across most LS variants, making this an essential component for builders integrating late-model Chevrolet powerplants into custom chassis or retrofit platforms.

Constructed from steel with black paint finish, the bellhousing provides reliable strength and corrosion resistance in engine bay environments. The SFI 6.1 certification ensures the component meets current racing and performance standards for flexplate containment and structural load distribution. Hardware is included for straightforward installation, eliminating the need for separate fastener sourcing. At 35.7 lbs, the assembly is substantial enough to handle the demands of T56 transmission coupling while maintaining the rigidity required in LS swap applications where tolerance stack-up directly impacts driveline performance and longevity.

This bellhousing is ideal for engine builders, fabricators, and enthusiasts executing LS swaps in non-original platforms or upgrading existing vehicles with modern powerplants and transmissions. T56 manual transmissions are a popular choice in conversion builds because they offer robust durability and clean gear ratios compared to original equipment. The Quick Time RM-6023 is the verified interface component for this drivetrain combination, eliminating guesswork in matching flexplate to bellhousing bore and bolt pattern. Proper bellhousing selection is critical—mismatched adapters can create binding, noise, and premature wear in the transmission input shaft bearing.
