These high flow brass jet extensions are a must for high power applications.

These are a full flow design and do not restrict or change the jets flow characteristics like the thread in style do. These are a " trapped" design.. insert Jet at the black end and screw the jet and ext to the metering block as an assembly.

we make these in our shop and can accommodate custom lengths if needed.

sold as a pair. instructions included.

for secondary jet use only. notched float required.

questions welcome and encouraged.
