4585198 RH Cylinder Head Gasket – 4.4L V8 LR3/L322/RRS

Restore proper sealing and top-end reliability on your 4.4L V8 engine with this Right-Hand (RH) Cylinder Head Gasket (Part No. 4585198). Designed to meet OEM specifications, this gasket ensures correct compression sealing, prevents coolant or oil cross-leaks, and maintains long-term durability under the high heat of Land Rover’s AJ-based 4.4L V8.

Ideal for overheating repairs, head rebuilds, or complete engine refreshes, this RH gasket fits the right cylinder head only. Order the matching LH gasket separately if servicing both banks.

Fits:

• LR3 / Discovery 3 4.4L V8 (2005–2009)

• Range Rover L322 4.4L V8 (2006–2009)

• Range Rover Sport 4.4L V8 (2006–2009)

Install tip: Replace head bolts during every head gasket service—these are torque-to-yield and cannot be reused.*
