FOX Factory Race Series QS3 Coil Shock Kits

FOX Technical Performance & Engineering

Key engineered features, technical highlights, and manufacturer specifications

• Fox’s Factory Series QS3 coil shock kits represent the latest evolution of the brand’s high‑performance suspension line.
• Engineered as the lightest shocks in the series, they carry the updated MY‑26 styling and are offered in both Coil and Float configurations to suit a range of off‑road applications.
• The “Rifle Bore” design incorporates spiral grooves along the interior of the shock body, allowing oil to bypass the main piston during the central portion of the travel.
• This fluid path reduces damping force in the ride zone, delivering a smoother, more plush feel for the rider.

• In the final 30 % of stroke the spiral grooves terminate, forcing oil through the main piston and dramatically increasing bottom‑out resistance.
• This transition provides a firm cushion against hard impacts while preserving comfort earlier in the travel range.
• The QSE rear‑track version adds an electronic lock‑out mode that can be engaged with a single click of a handle‑bar‑mounted button, giving riders instant control over suspension firmness without compromising the kit’s lightweight, performance‑focused architecture.

• Completely redesigned and refined Factory Series Shocks are the lightest yet!
• Available in Coil and Float series with updated MY 26 styling
• Rifle Bore have spiral grooves on the inside of the shock allowing oil to flow around the main piston reducing the damping force in the ride zone for a plush ride
• The grooves end through the final 30% of the travel forcing the oil to flow through the main piston resulting in a significant increase in bottom-out resistance to cushion hard hit
• QSE model rear track shocks include an electronic lock out mode with the simple click of a handlebar mounted button!
