Important Installation Notes: This kit is designed for models built from 2001 through September 2005 and fits LB7 and LLY engines only.

South Bend recommends ordering hydraulics upgrade (part number HYDX-MAX) for optimal performance.

Proper break-in is essential: drive 500 miles with stop-and-go driving before towing heavy loads to ensure maximum clutch life and performance.
