    PAC Valve Spring Retainers are a must have when upgrading your valvetrain. Valve springs with larger diameters and higher spring pressures will require new retainers.

    Beehive 300 Series Valve Spring Retainers are designed for smaller beehive springs and made from heat treated 4140 chrome moly steel with black oxide finish.

    PAC-Tuff 400 Series Valve Spring Retainers are constructed from 6AL4V Titanium alloy and they are completely sonic tested to aerospace standards prior to CNC-machining. Robust PAC-Tuff retainers are designed for standard to high durability.
