Lotus/Toyota 2ZR/1ZR/AR Titanium Valve Retainer Kit
We have noticed that valve springs are "just about" good enough for 7200rpm, so we have decided to lose some weight in the valvetrain. Unfortunately, there is not such a great choice of good quality and engineered parts for those engines so we have manufactured our own lightweight titanium valve retainers (45% lighter).
Our titanium retainers are lightweight and durable. These have been Plasma Nitrided for ultimate reliability which increases the surface hardness of the material.
Galling common for titanium retainers ( form of wear caused by adhesion between sliding surfaces) with these retainers this will not happen due to the fact they have been Nitrided.
Sold in sets of 16 pieces.
They are also available as a kit with upgraded springs here
