Description


Supertech Retainer Kit for the 4G63 DOHC Engines.

These Retainers are manufactured with high quality, military certified Titanium alloy, and are CNC machined for precise fit.

Lighter and stronger (by far) then the Mitsubishi stock retainers, and a must-have for those of you that like to live on the high-side of 8500 rpms, or with high-lift/duration bumpsticks! For more information, please visit this products webpage.
