The best kit out there for freshening up your Enderle cube-style barrel valve.

This kit not only provides all the correctly sized methanol/nitro safe o-rings and metering piston clips, but also new stainless screws and lock washers for reinstallation on your hat. O-rings are included to refurb the -6 idle check valve as well.

If your application requires gasoline compatible o-rings, please specify in the comments section of your order.
