1.025″ Tab & Notch Modular Valve Spring Retainer System

⚠️ NOTICE: Avoid inserting a modular notched spacer without a valve attached to it. The sharp edges at the notch can snag inside the bore, when attached to a valve it will slide smoothly.
⚠️ If you get a spacer without a valve stuck in the bore- use only wood or plastic (pen/marker, wood BBQ skewer) to slowly and evenly push and tap it out. DO NOT use a screwdriver or other metal prying tool!

→Need to make the skirt length a bit shorter? Apply even pressure and rub it in a figure 8 pattern on sandpaper placed over a flat surface.
