Item Description

*RB25DETT : SET Requires Tomei Valve Springs

NOT compatible with NEO 6

Direct replacement from the stock hydraulic lifters. Adjusted by shims.

Requires solid type camshafts.

Height of the base is 1mm extra. For Φ29 base circle camshafts.

Suited for TOMEI camshafts with 10.25mm lift.

High strength by cold forging,
lightweight. Weighs approximately 35g ( Stock is 57.5g)

High Strength Chrome-Moly Steel + Cold Forging

We adopt cold forging process to the high strength chro-moly steel. This enabled to reduce burden to the valves enormously while raising reliability at the super high RPM sharply.

Carburizing Surface Treatment

The surface was treated with the Carburizing process to increase the surface hardness which raises reliability for longer periods of time even in extreme conditions of performance engines. Carburizing is the process of increasing the carbon content in the metals surface through a heat process to implant carbon atoms into the crystal structure of the metal. This will result in a harder outer surface, while the core remains soft and tough.

The Solid Design

Although hydraulic lifter that is used in stock engines of RB20, VG30 or CA18 are contributed in making it maintenance free, it be comes the hindrance of high-speed rotation interns of tuning the engine. Also, since hydraulic lifter cannot adjust its height, it is impossible to use high lift camshaft. Accordingly, the tuning range and performance of RB20, VG30 and CA18 were restricted by H-lifter. On the other hand, In addition, it is required to use special camshaft designed only for the solid type camshaft, which has enlarged buffer part of the valve clearance.
