Frequently Asked Questions

Why do the camshafts need to be removed before fitting the head?
The 4D56U uses adjustable rocker arms — the camshafts and rockers must be removed to allow the head to be bolted down correctly, then refitted and rocker clearances set by the installer. This is standard procedure for this engine.

Does this suit both the 2WD and 4WD Triton?
Yes — this head suits both the 100kW 2WD and 130kW 4WD variants of the 4D56U engine. One head fits all Triton ML/MN and Challenger PB/PC models from 2009–2015.

Are the head bolts reusable?
No — the 4D56U uses torque-to-yield (TTY) stretch bolts which are single-use only. New bolts are included in this kit.
