High Precision Reinforced High-Nickel Alloy Pre-Assembled Cylinder Head Assembly for Mack E7 E-Tech Engine

Our 732GB5341M fully loaded 4-valve cylinder head is a premium direct replacement engineered exclusively for Mack E7 E-Tech heavy-duty diesel engines. Manufactured with reinforced high-nickel alloy castings to resist thermal cracking and deformation under extreme high-temperature and high-pressure working conditions, this assembly features enlarged coolant passages and thickened internal ribs that effectively dissipate heat and reduce heat stress.

Every finished head undergoes strict air leakage, hydraulic pressure and flatness testing to fully meet OEM dimensional tolerances. Pre-assembled with brand-new intake/exhaust valves, valve springs, retainers, valve guides and injector tubes for direct plug-and-play installation without extra assembly work.

Perfectly compatible with Mack heavy trucks ranging from 300HP to 400HP E7 E-Tech models, delivering stable combustion efficiency, excellent sealing performance, extended service life and reliable power output to cut your fleet's engine maintenance downtime and replacement costs significantly.
