Rifle Bore: Position-Sensitive Performance
The rear track shock in this kit utilizes Fox's Rifle Bore Technology. Spiral grooves inside the shock body allow oil to bypass the main piston during the "ride zone," creating a smooth, compliant feel for stutter bumps and trail cruising. As the shock compresses into the final 30% of travel, these grooves terminate, forcing all oil through the piston. This creates a massive increase in bottom-out resistance, allowing you to ride harder with less fatigue.
QS3: Tune in Seconds
The Quick Switch 3 (QS3) adjusters allow you to instantly adapt to changing trail conditions. Choose Position 1 for a plush morning ride, Position 2 for mixed chop, or Position 3 for high-speed ditch banging—all without taking your gloves off.
