Tilton Engineering 52-681 Aluminum Bellhousing GM LS 102-Tooth 5.5in Reverse Mount Starter

The Tilton Engineering 52-681 is a high-performance aluminum bellhousing designed specifically for GM LS-series engines. This precision-engineered component is built for use with 102-tooth flywheels and 5.5-inch clutches, featuring a rear-mount (reverse mount) starter configuration that provides secure mounting and easy serviceability.

Key Features:

• Lightweight aluminum construction resists flexing for maximum power transfer
• Side-bolt mounting starter design for secure attachment and easy access
• Compact design provides only 4.7 inches from crankshaft centerline to bellhousing bottom for improved ground clearance
• Compatible with transmissions featuring traditional GM 4-bolt mounting pattern and 4.68-inch register diameter
• Designed for use with Tilton 102-tooth flywheels and 5.5-inch clutches
• Natural aluminum finish

This bellhousing replaces Tilton part number 52-601 with an improved design. The rigid aluminum construction minimizes wear to driveline components while the compact footprint allows for better exhaust header clearance in tight engine bay applications. Ideal for racing and high-performance street applications where reliability and precise fitment are critical.
