Nissan Differential Cover RZ34 / Z34 / Z33
Part Number : HPDOP-N01
Scheduled to start delivery around November 2026!
By maximizing the internal volume, oil capacity is increased by approximately 500cc.
Featuring large cooling fins, it suppresses viscosity drop and oil film breakdown caused by rapid increases in differential oil temperature, preventing damage to the LSD and final gear.
Installing it together with the HPI Differential Oil Cooler delivers even higher cooling performance for stable, continuous driving.
Designed with three service ports (3/8 NPT x 2, 1/8 PT x 1), allowing for the installation of an oil temperature sensor and oil line routing.
For race use, the differential mount can be secured at two points by adding an additional differential mount bolt to increase mounting rigidity.
(Modifications to the rear subframe are required when adding the extra bolt.)
