1.025″ Tab & Notch Modular Valve Spring Retainer System

⚠️ NOTICE: Do not insert modular notched spacer without a valve attached to it. The Titanium spacers are slightly out of round because it is very thin walls, and this makes the sharp edges catch inside the bore when inserted. When attached to a valve, it brings it back to round and fits very smoothly inside the bore!
⚠️ If you get a spacer without a valve stuck in the bore- use only wood or plastic (pen/marker, wood BBQ skewer) to slowly push and tap it out. DO NOT use a screwdriver or other metal prying tool!

→Need to make the spacer a bit shorter? Rub it in a figure 8 pattern on sandpaper placed over a flat surface.
