The JEGS 555-60347 bellhousing adapter kit adapts GM Gen III and Gen IV LS engines and Gen V LT1 and LT4 engines to a wide range of manual transmissions, including the Muncie, Jerico, T5, T56, TKO 500 and TKO 600, and TKX. That range makes one adapter cover most LS and LT swap combinations, whether the transmission behind the engine is an original four-speed or a modern five- or six-speed. The steel bellhousing is machined on both the engine and transmission faces so the transmission input shaft stays concentric with the crankshaft centerline, which is what keeps the clutch disc, pilot bearing, and release bearing wearing evenly. Engine bolts, transmission bolts, and a block plate are all in the box, so the driveline can be closed up without a separate hardware order.

JEGS 555-60347 GM LS, LT Engine to Transmission Bellhousing Adapter Kit Includes:

• Steel bellhousing adapter
• Engine mounting bolts
• Transmission mounting bolts
• Block plate

JEGS 555-60347 GM LS, LT Engine to Transmission Bellhousing Adapter Kit Features:

• Fits GM Gen III and Gen IV LS engines and Gen V LT1 and LT4 engines
• Adapts to Muncie, Jerico, T5, T56, TKO 500, TKO 600, and TKX manual transmissions
• One bellhousing adapter covers both original four-speed and modern five- and six-speed transmission swaps
• Universal fit design is not vehicle specific, so it suits swaps and factory-style rebuilds alike
• Steel construction resists flex under high torque loads
• Machined engine and transmission mounting faces hold the input shaft on the crankshaft centerline
• Engine-side bolt pattern matches the factory LS and LT block for a bolt-on installation
• Set up for hydraulic clutch operation
• Block plate closes the joint between the engine block and the adapter to keep road debris away from the flywheel and clutch

JEGS 555-60347 GM LS, LT Engine to Transmission Bellhousing Adapter Kit Notes:

• Not SFI approved
• This is a universal fit bellhousing adapter and is not vehicle specific, so confirm transmission tunnel and floor clearance before installation in a swap chassis
• Clutch assembly, flywheel, and hydraulic release bearing are sold separately
• Match the clutch and release bearing to the specific transmission being installed, since input shaft length and bearing retainer diameter vary between the Muncie, Jerico, T5, T56, TKO, and TKX
• Verify clutch stack height and release bearing travel during assembly to set correct clutch engagement
