Most Tippmanns use a drive spring to push the hammer forward into the valve. This kit includes 6 springs of varying strength so that you can use the spring that best works for your setup. Silver is the weakest, then green, blue, red, black, and then steel gray is the strongest. The steel gray spring is the spring TechT uses with Zero Kick Hammers. Its slightly shorter, but the wire is thicker, and it packs a pretty good punch. This DELUXE Kit also includes three Trigger Springs and Two Valve Springs. This way you can fine tune the hammer, valve and trigger. No matter what the setup, low pressure or high pressure, the deluxe spring kit is what you need to get the most out of your Tippmann
