Key Features
- Fitment: Ski-Doo Renegade & MXZ with 137" rMotion (2021-2025)
- Front Track: 2.0 Zero QS3 (Large Body for Cooling)
- Rear Track: 1.5 Zero QS3 with Rifle Bore Technology
- Adjustments: QS3 (Soft/Med/Firm) on both shocks
Rifle Bore: Intelligent Damping
The rear track shock features Fox's Rifle Bore Technology. Spiral grooves inside the body allow oil to bypass the main piston during the "ride zone," creating a smooth, compliant feel for trail chatter. As the shock compresses into the final 30% of travel, these grooves terminate, forcing all oil through the piston. This creates a massive ramp-up in damping force to prevent bottoming out on big hits.
2.0 Front Track Advantage
On 137" sleds, the front track shock takes significant abuse. This kit upgrades that specific shock to a 2.0" body, increasing oil volume and cooling capacity to ensure fade-free performance during long, aggressive rides.
QS3: Tune in Seconds
Both shocks feature the Quick Switch 3 (QS3) adjuster. Instantly toggle between 3 specific settings (Soft, Medium, Firm) to adapt to the trail conditions without counting clicks or removing your gloves.
