Built for the 2UZ 4.7L V8, the Exhaust Systems Australia TOYOTA-LANDCRUISER-UZJ100-LEXUS-LX470-2UZ-4-7L-V8-STEEL-HEADER-GASKET-2 is a steel header gasket listed to fit the Toyota Landcruiser UZJ100 and its Lexus LX470 twin — one V8, two badges, one sealing face.
Why the 2UZ V8 needs a dedicated gasket
The 2UZ 4.7L V8 runs a bank of exhaust ports each side, and this gasket is cut to that port pattern. It seals the joint where the extractor or manifold flange meets the head, and steel is used so it survives the heat cycling a hard-worked V8 puts through it. The 2UZ is the common thread between the UZJ100 Landcruiser and the LX470, which is why one gasket covers both.
Landcruiser or LX470 — does the same part cover both?
Yes. The UZJ100 Landcruiser wagon and the Lexus LX470 share the 2UZ 4.7L V8, so the head and port face are the same despite the different badges. A header gasket only seals if that port pattern matches exactly, so confirm your head and manifold setup with the workshop before ordering, and check how many you need given the engine has a bank each side.
Is this a performance part?
No — it's a service and fitment item, not a power part. Its only job is to stop exhaust escaping where the manifold bolts to the 2UZ's head. You'd reach for one whenever the extractors or manifold come off: an extractor fit, a head job, or to cure a blowing leak. Refitting a disturbed old gasket is a common reason a leak comes straight back, so a fresh one any time that flange is opened is sensible.
What does fitting involve at our Illawarra workshop?
Oak Flats Muffler Men fits header gaskets like this as part of extractor and manifold work across the Illawarra. On a heavy V8 wagon like the UZJ100 or LX470 there's bodywork and accessories to clear before the flange is accessible, so it's almost always done within a larger job. We clean the faces, check the flange for distortion and torque the fasteners evenly. At a recommended retail of $26 the gasket is the small part of the work — send your details and we'll confirm it matches your 2UZ V8 first.

Common questions
Will one gasket cover both the Landcruiser and the LX470?
Both the UZJ100 Landcruiser and Lexus LX470 share the 2UZ 4.7L V8, so this gasket is listed for both. Confirm your head and manifold setup and how many you need with the workshop.
What's it made from and why?
Steel, so it holds the seal through the heat cycling of the 2UZ V8 where the manifold bolts to the head.
Can you fit it for me?
Yes, at our Illawarra workshop, normally as part of extractor or manifold work on the 2UZ. We confirm it matches your engine before fitting.
