Description
Ski-Doo T-Motion Lockout Kit Gen 4 850 (ZRP) gives riders precise control and enhanced stability when tackling technical terrain. Built for 2017 and newer Gen 4 Ski-Doo 850 models, this ZRP-engineered lockout eliminates the excessive lateral flex of the factory T-Motion system, delivering sharper handling and more predictable suspension behavior.
Why Lock Out the T-Motion
The stock T-Motion joint allows the rear suspension to pivot side-to-side, which can feel loose during side-hill climbs or technical maneuvers. By installing the ZRP lockout kit over the spherical bearing, you restrict unwanted motion and transfer more control to the skis. As a result, your sled tracks straighter on steep slopes and reacts more consistently to rider input.
Construction & Material
Each washer in the kit is machined from bearing-grade bronze—a self-lubricating, high-durability metal chosen for its resistance to wear under load. This material ensures the kit retains tight tolerances over long seasons of hard riding. Moreover, the bronze finish resists corrosion from snow and road salt, ensuring smooth articulation and minimal maintenance.
Installation & Fitment
Installation is simple: one washer installs on each side of the spherical bearing without any modification or special tools. The kit fits 2017 and newer Ski-Doo Gen 4 models, including Summit 850, Freeride 850, and Backcountry 850 configurations. Always verify your chassis generation before installation.
Performance & Handling
After installing, you’ll immediately notice more direct feedback through the handlebars, improved climbing balance, and reduced body roll. Consequently, technical riders can hold a sidehill with less counter-steer and carve with better accuracy. However, locking out the T-Motion changes suspension loading, so riders accept full responsibility for setup and tuning after modification.
Why Choose ZRP
ZRP designs precision components that enhance control without sacrificing reliability. The Ski-Doo T-Motion Lockout Kit Gen 4 850 (ZRP) continues that legacy—easy to install, durable, and engineered for riders who demand precision on every climb.
