View Instructions Find a Distributor

The 96201-23K kit replaces both the original 4-spooled converter regulator valve and the original 2-spooled version.
Valve is manufactured from hardcoat anodized aluminum and incorporates four valve spools to provide better stability and prevent bore wear.
Annular grooves have also been added to center the valve in the bore and prevent side loading that leads to bore wear.
Two replacement springs are included to compensate for the oversized valve, to reduce the excessive spring force that accelerates bore wear, and to work with either the original 2- or 4-spooled OE design.
Either [96201-TL3] or F-96201-TL23 can be used to enlarge the bore to accept the oversized valves, for all applications.

Note

Reamer kit 96201-TL3 is no longer in production but may be available from distributor inventory.
