Ride harder with less fatigue without a compromise of durability. Experience a new sense of control on the snow due to velocity and position-sensitive damping technology. Quickly adjust the compression damping with Fox's QS3 to suit snow conditions. Three positions keep the gloves on and the adjustment simple. Focus on riding instead of counting clicks. Fox's position-sensitive damping technology, Rifle Bore, is now applied to the Factory Race Series rear track shock. Spiral grooves inside the shock allow the oil to flow around the main piston, reducing the damping force in the ride zone for a plush feel. The grooves terminate through the final 30% of the travel, forcing oil to flow through the main piston. The final result is a significant increase in bottom-out resistance to cushion hard hits.\n\u003cbr\u003e\u003c\/p\u003e\u003cp\u003eThe FOX Part Number 853-04-001 Quick Switch (QS) coil shock is engineered specifically for snow trail and crossover applications, bringing FOX's renowned performance to the backcountry. Designed with a lightweight spring and shock assembly, this suspension component allows riders to push their limits with less fatigue while maintaining high durability and control. The innovative velocity and position-sensitive damping technology enables precise adjustments to adapt to varying snow conditions, giving riders a tailored riding experience without the hassle of complex setups. The QS3 three-position compression adjuster allows quick changes with gloves on, so riders can focus more on the ride and less on adjustments.\u003cbr\u003eFOX's rifle bore technology, now implemented in the Factory Race Series rear track shock, utilizes spiral grooves inside the shock to optimize oil flow around the piston. This results in a plush ride during normal operation and significantly increased bottom-out resistance to absorb hard impacts effectively. The shock's internal floating piston (IFP) ensures consistent performance and enhances the shock's durability over time. Fully rebuildable and re-tunable, it offers long-term value and customization options for serious snow riders.\u003cbr\u003eConstructed with high-quality aluminum mounting hardware and featuring Fox's ice scraper technology (FIST), this shock is designed for high flow velocity-sensitive damping. It provides an excellent balance of plushness and resistance, ensuring optimal performance across a variety of snow conditions. Suitable for a range of Ski-Doo models, including 2021 and 2022 MX Z X and MX Z TNT series with 129\u003c\/p\u003e\n\n\u003cp\u003eProduct Type: Suspension\n\u003cbr\u003eSegment: Snow\n\u003cbr\u003eDivision: Suspension \u0026amp; Swingarms\n\u003cbr\u003eClass: Suspension \u0026amp; Components\n\u003cbr\u003eSub Class: Shocks \u0026amp; Components\u003c\/p\u003e\n\n\u003cp\u003eFITMENT:\n\u003cbr\u003e2021 Ski-Doo MX Z X 600R E-TEC 129\"\/1.25\"\n\u003cbr\u003e2021 Ski-Doo MX Z X 850 E-TEC 129\"\/1.25\"\n\u003cbr\u003e2021 Ski-Doo MX Z X-RS 600R E-TEC 129\"\/1.25\"\n\u003cbr\u003e2021 Ski-Doo MX Z X-RS 850 E-TEC 129\"\/1.25\"\n\u003cbr\u003e2022 Ski-Doo MX Z TNT 600R E-TEC 129\"\n\u003cbr\u003e2022 Ski-Doo MX Z TNT 850 E-TEC 129\"\n\u003cbr\u003e2022 Ski-Doo MX Z X 600R E-TEC 129\"\/1.25\"\n\u003cbr\u003e2022 Ski-Doo MX Z X 850 E-TEC 129\"\/1.25\"\n\u003cbr\u003e2022 Ski-Doo MX Z X-RS 600R E-TEC 129\"\/1.25\"\n\u003cbr\u003e2022 Ski-Doo MX Z X-RS 850 E-TEC 129\"\/1.25\"\n\u003cbr\u003e2023 Ski-Doo MX Z Blizzard 600R E-TEC 129\"\n\u003cbr\u003e2023 Ski-Doo MX Z Blizzard 850 E-TEC 129\"\n\u003cbr\u003e2023 Ski-Doo MX Z X-RS 600R E-TEC 129\"\/1.25\"\n\u003cbr\u003e2023 Ski-Doo MX Z X-RS 850 E-TEC 129\"\/1.25\"\n\u003cbr\u003e2024 Ski-Doo MX Z Adrenaline 600R E-TEC 129\"\n\u003cbr\u003e2024 Ski-Doo MX Z Adrenaline 600R E-TEC 137\"\n\u003cbr\u003e2024 Ski-Doo MX Z Adrenaline 600R E-TEC w\/ Blizzard Package 129\"\n\u003cbr\u003e2024 Ski-Doo MX Z Adrenaline 600R E-TEC w\/ Blizzard Package 137\"\n\u003cbr\u003e2024 Ski-Doo MX Z Adrenaline 850 E-TEC 129\"\n\u003cbr\u003e2024 Ski-Doo MX Z Adrenaline 850 E-TEC 137\"\n\u003cbr\u003e2024 Ski-Doo MX Z Adrenaline 850 E-TEC w\/ Blizzard Package 129\"\n\u003cbr\u003e2024 Ski-Doo MX Z Adrenaline 850 E-TEC w\/ Blizzard Package 137\"\n\u003cbr\u003e2024 Ski-Doo MX Z X 600R E-TEC 129\"\/1.25\"\n\u003cbr\u003e2024 Ski-Doo MX Z X 600R E-TEC 129\"\/1.5\"\n\u003cbr\u003e2024 Ski-Doo MX Z X 600R E-TEC 137\"\/1.25\"\n\u003cbr\u003e2024 Ski-Doo MX Z X 600R E-TEC 137\"\/1.5\"\n\u003cbr\u003e2024 Ski-Doo MX Z X 850 E-TEC 129\"\/1.25\"\n\u003cbr\u003e2024 Ski-Doo MX Z X 850 E-TEC 129\"\/1.5\"\n\u003cbr\u003e2024 Ski-Doo MX Z X 850 E-TEC 137\"\/1.25\"\n\u003cbr\u003e2024 Ski-Doo MX Z X 850 E-TEC 137\"\/1.5\"\n\u003cbr\u003e2024 Ski-Doo MX Z X-RS 600R E-TEC 129\"\/1.25\"\n\u003cbr\u003e2024 Ski-Doo MX Z X-RS 600R E-TEC 129\"\/1.5\"\n\u003cbr\u003e2024 Ski-Doo MX Z X-RS 600R E-TEC 137\"\/1.25\"\n\u003cbr\u003e2024 Ski-Doo MX Z X-RS 600R E-TEC 137\"\/1.5\"\n\u003cbr\u003e2024 Ski-Doo MX Z X-RS 600R E-TEC w\/ Competition Package\n\u003cbr\u003e2024 Ski-Doo MX Z X-RS 850 E-TEC 129\"\/1.25\"\n\u003cbr\u003e2024 Ski-Doo MX Z X-RS 850 E-TEC 129\"\/1.5\"\n\u003cbr\u003e2024 Ski-Doo MX Z X-RS 850 E-TEC 137\"\/1.25\"\n\u003cbr\u003e2024 Ski-Doo MX Z X-RS 850 E-TEC 137\"\/1.5\"\n\u003cbr\u003e2024 Ski-Doo MX Z X-RS 850 E-TEC Turbo R w\/ Competition Package\u003c\/p\u003e","brand":"FOX","offers":[{"title":"Default Title","offer_id":47678640423069,"sku":"530-1259","price":1449.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0742\/9242\/8957\/files\/bb3c-6877d808e4371.png?v=1772043823","url":"https:\/\/thepartjungle.com\/products\/fox-part-number-853-04-001-quick-switch-coil-shock-for-snow-trail-crossover-riding","provider":"The Part Jungle","version":"1.0","type":"link"}
