Redback Headers.2L 1HZ (01/1990 - 02/1998) (RBH723) Fits Toyota. Fast.
Category: Extractors and headers


The Redback RBH723 is a header set listed to fit the 80 Series Toyota Landcruiser with the 4.2L 1HZ engine, from 01/1990 to 02/1998. It replaces the factory exhaust manifold on that diesel Cruiser, listed at $1,575.
The RBH723 is a header set for the 80 Series Landcruiser running the 4.2L 1HZ diesel. Headers bolt to the cylinder head in place of the cast factory manifold and form the front of the exhaust. This is a Redback fitment specific to the 1HZ 80 Series, and the listing covers the header set; downstream pipework, any cat and the muffler are matched separately to the build.
Headers replace the single cast manifold with separate tubes that merge downstream, giving exhaust a clearer path off the head than the factory casting. On a heavy diesel 4x4 like the 1HZ Cruiser they're a common exhaust upgrade and an engine-bay job. Because they sit at the very front of the system and bolt straight to the head, the set is matched to the specific 4.2L 1HZ engine. No power or sound figures are published; those depend on the full build.
It's listed to fit the 80 Series Toyota Landcruiser with the 4.2L 1HZ engine from 01/1990 to 02/1998. Confirm your exact engine and build with the workshop before ordering — the 1HZ note matters, since other Cruiser engines use different headers.
