This adaption package is designed to fit the 6.6L (LB7, LLY, LBZ & LMM) Duramax V8 turbo diesel engine and Allison 5 or 6 speed automatic transmission to the Nissan Patrol GU transfer case.

This custom made adaption kit is engineered and manufactured exclusively by Mark's 4WD Adaptors. It can be used in any Nissan Patrol, however we recommend using the ZD30 manual tailshafts, crossmember and low range lever for ideal engine position.

The Nissan transfer case stays in the factory position when using our adaptor housing allowing you to run standard drive shafts. We supply a new input gear for the transfer case which accepts the factory Allison 4WD output shaft - no coupler shaft is required. The oil filter rotation kit allows for the use of the factory Duramax oil filter eliminating the need for a remote oil filter set up. Our cast aluminium sump is designed to clear the front diff and track rod in the Patrol. Engine mounts are weld in and require the original chassis posts to be removed.

Note 3: Some early LB7 engines had a different oil filter mount which needs to be changed to fit our oil filter rotation kit.
