Fox Racing Shocks 853-02-052 1.5 ZERO QS Rear Track Shock

The Fox Racing Shocks 1.5 ZERO Quick Switch (QS) coil shock represents the next generation of lightweight mountain snowmobile suspension technology, engineered specifically for rear track applications on Ski-Doo Gen5 sleds. Designed to deliver exceptional performance in backcountry conditions, this shock allows riders to push harder with less fatigue while maintaining durability and control on top of the snow.

Quick Switch (QS) Technology:

• Easy adjustment of compression and rebound damping to match riding conditions
• Three-position switching keeps adjustments simple, allowing focus on the ride instead of counting clicks
• Equipped with lockout mode to prevent trenching in deep snow or when climbing steep faces
• Tool-free adjustability for on-the-fly tuning

Lightweight Design:

• Optimized through strategic material reduction without sacrificing ride quality or structural integrity
• Redesigned coil springs retain the same spring rate with fewer coils
• Built from lighter steel alloy, delivering same performance at approximately half the weight
• Reduced outboard weight enhances sled handling and reduces rider fatigue

Position-Sensitive Damping:

• Technology derived from desert truck racing, now applied to mountain sled shocks
• Spiral grooves inside the shock allow oil to flow around the main piston, reducing damping force in the ride zone for a plush feel
• Bypass grooves terminate through the final 30% of travel, forcing oil through the main piston only
• Provides significant increase in bottom-out resistance to cushion hard hits and inspire confidence on big sends

Temperature-Stable Performance:

• Coil-sprung design maintains linear feel regardless of temperature fluctuations
• Keeps sled setup quick and simple in varying conditions
• Consistent performance from first ride to last

This Factory Race Series shock is designed for serious mountain riders who demand the ultimate in weight savings, adjustability, and performance. The combination of Fox's proven QS technology with the lightweight ZERO platform delivers exceptional control and confidence in the most challenging backcountry terrain.
