The **Polaris Matryx SwitchBack Assault 850/650 AXYS Left A-Arm Upper (Model 1824756-067, 2021 2024)** is a high-performance, all-terrain utility vehicle designed for those who demand versatility, durability, and cutting-edge innovation in their off-road adventures. Engineered as part of Polaris s advanced Matryx lineup, this model combines the rugged prowess of the Assault series with the refined handling and advanced technology of the AXYS platform, making it an exceptional choice for both recreational enthusiasts and professional operators. The **850/650** designation indicates its powerful **850cc V-Twin engine**, paired with a **650cc auxiliary electric motor** in the AXYS system, delivering a seamless blend of traditional power and electric assist for enhanced efficiency and reduced emissions. This hybrid configuration not only provides a smooth, responsive ride across rough terrain but also offers a more environmentally conscious option with its electric mode, ideal for shorter trips or urban commutes.
At the heart of the SwitchBack Assault s appeal is its **adaptive suspension system**, which dynamically adjusts to varying terrain conditions, ensuring a stable and comfortable ride whether you're tackling deep mud, rocky trails, or paved roads. The **Left A-Arm Upper** (part number 1824756-067) is a critical component of this suspension setup, contributing to the vehicle s superior articulation and load-bearing capacity. Crafted from high-strength materials, this upper control arm is engineered to withstand the stresses of heavy-duty use while maintaining precision in steering and handling. Its robust construction, combined with the SwitchBack s **articulated frame and independent suspension**, allows the vehicle to navigate obstacles with ease, making it one of the most capable UTVs on the market for tasks ranging from farming and construction to extreme off-roading and tactical applications.
The **AXYS platform** elevates the Assault further by integrating a **12V battery system** with the electric motor, offering a range of operational modes. In **electric-only mode**, the vehicle can glide silently and smoothly at lower speeds, reducing wear on the engine and fuel consumption. When transitioning to **hybrid mode**, the V-Twin engine takes over for higher speeds or demanding climbs, while the electric motor assists with torque and efficiency. This dual-power system not only enhances performance but also extends the vehicle s operational flexibility, making it suitable for both short urban errands and long-distance off-road excursions. The **SwitchBack s** unique **articulated frame** further amplifies its off-road capabilities, allowing the front and rear axles to move independently, which significantly improves ground clearance and maneuverability over uneven terrain.
For those who prioritize functionality, the Assault 850/650 AXYS is equipped with a **spacious and customizable cargo area**, capable of carrying heavy loads with ease. The **left A-arm upper** plays a role in maintaining structural integrity under load, ensuring that the vehicle remains stable and responsive even when fully laden. Additionally, the **650cc electric motor** contributes to a quieter operation, reducing noise pollution in both residential and professional settings. The vehicle s **digital dashboard** provides real-time feedback on speed, battery status, and engine performance, while the **Polaris Link app** allows for remote diagnostics, vehicle monitoring, and even over-the-air updates, ensuring that your UTV stays at the top of its game with minimal downtime.
Safety and comfort are also paramount in the design of this model. The **AXYS platform** includes features like **regenerative braking**, which helps recharge the battery while slowing down, and **adaptive cruise control**, which maintains a set speed while adjusting for terrain. The **SwitchBack s** high ground clearance and robust suspension work together to absorb shocks, reducing fatigue on long rides. For added protection, the vehicle is available with optional **roll cages, roof racks, and winches**, making it a formidable choice for extreme off-roading or utility work. The **2021 2024 model years** of this UTV have also seen refinements in ergonomics, with improved seating positions, better controls, and enhanced visibility, ensuring that operators can focus on the task at hand without compromise.
