SPRiT MX Supreme Springs
MX Supreme is SPRiT's 'standard' single stage line of springs. These are the highest precision springs available on the market, with an allowed deviation of only 0.3g (0.5%). Made in Korea from premium Japanese and Korean spring steel. The number on the springs is the amount of grams required to bottom out a switch with that spring inside.
Each bag contains ~100 springs. For reference, the Supreme 63.5g spring is 13.75 mm long.
