Redback Headers.2 HZJ70 HZJ75 HZJ78 (03/1990 - 11/1999) (SKU: RBH722) Engineered
Category: Extractors and headers


The Redback RBH722 is a header set listed to fit the 4.2 1HZ Toyota Landcruiser — the HZJ70, HZJ75 and HZJ78 — from 03/1990 to 11/1999. It replaces the factory exhaust manifold on that diesel Cruiser, listed at $1,509.
The RBH722 is a header set for the 1HZ 4.2 Landcruiser in HZJ70, HZJ75 and HZJ78 forms. Headers bolt to the cylinder head in place of the cast factory manifold and form the front of the exhaust. The same set covers the three HZJ chassis codes because they share the 1HZ driveline of the era. This listing is the header set; downstream pipework 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 engine-bay upgrade and the front-most part of the system. Because they bolt straight to the head, the set is matched to the 1HZ engine specifically. No power or sound figures are published; those depend on the whole build.
It's listed to fit the 4.2 1HZ Landcruiser in HZJ70, HZJ75 or HZJ78 form from 03/1990 to 11/1999. Confirm your exact chassis code and engine with the workshop before ordering — the 1HZ note matters, since other Cruiser engines use different headers.
