SPRiT Designs Slow Extreme 3 Ultra Springs

SPRiT MX Slow Extreme III springs are longer than your typical springs and feature a higher starting force. Perfect for gamers and typists who want to prevent accidental keypresses and those who prefer a heavier switch without increasing their bottom out weight. They are within 0.5% deviation, whereas stock springs are typically within 10% deviation! Note that SE editions are within 0.3% deviation - they are no different than non-SE editions other than superior tolerance.

Slow Extreme III springs feature a +3g starting force compared to their Slow Extreme II counterparts, and +6g compared to Slow Extreme I
