The Zamp Z-20 Photochromatic Shields go from bright to dark racing conditions without having to change shields. One shield works for Night or Day!

The new Z-20 Photochromatic Shield come is four different options. Choose smoothly transitions from (1) clear to dark; (2) clear prism to red prism; (3) clear prism to gold prism, or (4) clear prism to blue prism (or vice versa) depending on the brightness of the race track without having to change the shield!

Zamp-Racing recommends that you periodically change shields for better vision and safety.

NOTE (1): Zamp Racing DOES NOT recommend using Racing Optic Perimeter Seal Laminated tear-offs on Coated Shield (including ALL Z-20 and Z-24 Prism Shields). They can have a reaction that can potentially damage the shield or shorten the longevity of the shield. The standard non-perimeter seal has no issue.

NOTE (2): If your tear-offs are not allowing the photochromatic to work, it is because the tear-off or adhesive is blocking the UV light. Z-Optics tear-offs do not block UV light, allowing the photochromatic shields to work.

NOTE: DO NOT USE power tools or overtighten screws when changing shields.

Step 1 - Lay a towel on a flat surface and set the helmet on it.

Step 2 - Remove the shield pivot tensioners on each side. (This is the smaller crew on the sides of the shield.)

Step 3 - Remove the shield pivot screws on each side. (This is the larger screw on the sides of the shield. For best results, we suggest using a quarter to loosen/tighten these screws).

Step 4 - Remove the shield. We suggest using a soft cloth towel to wipe down the rubber seal as well as where the shield mounts to the helmet for best results.

Step 5 - Place the new shield on the helmet. There are two white washers that go between the shield and helmet, make sure these are in place before re-installing the shield pivot screws.

Step 6 - Hand thread the shield pivot screws to hold the shield in place. Once hand threaded, use a quarter to tighten until snug with the helmet shell. Do not over-tighten.

Step 7 - Hand thread the shield pivot tensioners, then tighten to desired tension for shield movement.
