QS3 shocks from FOX represent a breakthrough in performance and adjustability. Think of it as three performance shocks in one. Giving you performance akin to the LXR, the Sno Pro, and the RR. How? Set the clicker to number 1. Like the LXR, the ride is smooth, comfortable, confident. Click it up a notch to setting 2, and you’ll straighten out the corners like a Sno Pro. When the competition heats up, click to number 3 and go head to head with an RR. This remarkable shock represents the first time you’ll actively adjust your shocks to suit the riding conditions (without removing your gloves). Top-of-the-line FOX quality is apparent. The FOX ZERO QS3 is a premium coil-over shock boasting a forged aluminum reservoir.

Ultra quick, super simple shock adjustability is now a reality thanks to the new FOX QS3 shocks
