Redback Headers.2 HZJ70 HZJ75 HZJ78 1990- (RBH041) fits selected vehicle applications.
Category: Extractors and headers


The Redback RBH041 is a set of headers listed to fit the Toyota Landcruiser 1HZ 4.2 (HZJ70, HZJ75 and HZJ78) from 1990. It replaces the factory manifold with tuned tubes and carries a recommended retail of $909.
Headers (extractors) replace the cast exhaust manifold with separate tubes merging into a collector, giving the 1HZ a freer path out of the head. This part is the front of the exhaust only; the pipework, any cat and the muffler behind the collector are separate. The diameter and material aren't published by Redback in our data, so the workshop confirms the part directly rather than us quoting numbers we can't trace.
It's listed for the 1HZ 4.2 Landcruiser in HZJ70, HZJ75 and HZJ78 form from 1990. Those are different cab and chassis variants on the same engine family, so we match the listing to your exact model before ordering. Tell us your chassis code and we'll confirm the RBH041 suits it.
Headers sit ahead of the emissions and silencing hardware, so road compliance depends on the complete system and how the vehicle is presented for registration in NSW. We don't claim a header is legal on its own — confirm the requirements for your build with the workshop.
Oak Flats Muffler Men fits 70 Series header sets in-house across the Illawarra. We check the head studs and the collector flange while the old manifold is off, then mate the RBH041 up with fresh gaskets. Book the Cruiser in and we'll confirm clearances on the hoist.
