Review ARCTIC CAT Spar Rear Axle Suspension fits TWIN F8 F6 F5 F570 2010–2014

The Arctic Cat 3604 series, spanning models like the **3604-300**, **3604-472**, **F8**, **F6**, **F1000**, **F5 Twin Spar**, and **F570**, represents a pinnacle of off-road performance, engineered for riders who demand relentless power, cutting-edge suspension technology, and unmatched durability in the most demanding terrains. Introduced across the 2010 to 2014 model years, these ATVs are built to conquer everything from rugged backcountry trails to high-performance racing circuits, blending Arctic Cat s legendary craftsmanship with advanced engineering. The **3604-300** and **3604-472** serve as the foundational models, offering a balance of power and versatility, while the **F-series** variants particularly the **F8**, **F6**, and **F1000** push the boundaries with high-octane performance, featuring upgraded engines, aggressive styling, and precision-tuned suspension systems designed for aggressive riding. The **F5 Twin Spar** and **F570** stand out as the apex of this lineup, combining Arctic Cat s signature **Rear Axle Suspension (RAS)** with a twin-spar chassis for enhanced rigidity and handling, making them ideal for both trail domination and competitive racing.

At the heart of these ATVs lies Arctic Cat s **liquid-cooled, high-performance engines**, delivering explosive torque and sustained power across a wide RPM range. The **F8** and **F1000** models, in particular, are equipped with Arctic Cat s most potent engines of the era, producing **472cc** and **1000cc** displacements respectively, with the **F1000** offering a rare blend of brute force and precision for riders tackling extreme terrain or high-speed racing. The **F6** strikes a middle ground with its **600cc** engine, providing a perfect balance of power and fuel efficiency for those who seek versatility without sacrificing performance. All models feature **Arctic Cat s legendary fuel-injected engines**, ensuring consistent power delivery, improved throttle response, and reduced emissions features that were groundbreaking in their time and remain hallmarks of Arctic Cat s engineering philosophy.

The **Rear Axle Suspension (RAS)** system is one of the most innovative and defining features of these ATVs, particularly in the **F5 Twin Spar** and **F570** models. Unlike traditional ATVs with front-only suspension, the RAS system on these Arctic Cats incorporates a **fully independent rear suspension**, allowing the rear wheels to move independently of the front, significantly improving traction, stability, and ride comfort over rough terrain. This system is complemented by **Arctic Cat s Twin Spar chassis**, a lightweight yet ultra-rigid frame construction that minimizes flex and enhances handling precision. The result is an ATV that not only absorbs impacts seamlessly but also delivers razor-sharp steering and cornering capabilities, making it a favorite among racers and serious off-road enthusiasts. The suspension is further refined with **adjustable damping** on select models, allowing riders to fine-tune the ride height and firmness to match their weight, terrain, and riding style.

The **F5 Twin Spar** and **F570** models take this performance ethos to the next level with their **aggressive, aerodynamic styling** and **high-performance components**. The **F570** is often regarded as one of the most iconic and sought-after Arctic Cats of the era, featuring a **sleek, low-profile design** with a **wide stance** that enhances stability at high speeds. Its **twin-spar chassis** is paired with **Arctic Cat s proprietary suspension tuning**, which includes **long-travel shocks** and **reinforced linkages** to handle the most extreme jumps and impacts. The **F5 Twin Spar**, while slightly more approachable for everyday trail riding, retains the same chassis rigidity and suspension sophistication, making it a versatile choice for both recreational and competitive use. Both models are equipped with **high-performance brakes**, including **front disc brakes** and **rear drum or disc options**, ensuring reliable stopping power even under heavy loads or in high-speed racing scenarios.

For riders who demand the ultimate in off-road capability, the **F8** and **F1000** models offer a **more aggressive, race-ready package** with **stiffer suspension tuning**, **heavier-duty drivetrain components**, and **enhanced cooling systems** to handle prolonged high-performance use. These models are often outfitted with **racing-specific accessories**, such as **spoilers, roll cages, and lightweight racing seats**, making them ideal for **dirt bike racing, ATV motocross, and extreme trail riding**. The **F1000**, in particular, is a powerhouse that punches well above its weight class, capable of **blistering top speeds** while maintaining the agility and control expected from an Arctic Cat. Meanwhile, the **F6** serves as a more accessible entry point into high-performance ATV riding, offering a **refined 600cc engine** that provides plenty of power for trail riding, utility work, or light racing without the overwhelming power of the larger displacements.

In terms of **build quality and durability**, Arctic Cat s 3604 series is constructed from the highest-grade materials, including **high-strength steel frames**, **forged aluminum components**, and **heat-treated suspension parts** that are built to last. The **RAS system** is particularly robust, designed to withstand the rigors of **rock crawling, jumping, and high-speed cornering** without compromising performance. The **transmission** is a **6-speed manual** (with some models offering an optional **automatic transfer case** for easier handling), providing smooth, precise gear shifts that allow riders to optimize power delivery for any situation. The **exhaust systems** are also engineered for both performance and durability, featuring **stainless steel construction** and **high-flow mufflers** to maximize power output while minimizing backpressure.

For those who prioritize **versatility and utility**, the **3604-300** and **3604-472** models offer a more balanced approach, combining **Arctic Cat s signature power** with **practical features** such as **spare tire mounts, towing hooks, and durable cargo racks**. These models are well-suited for **farm work, hunting expeditions, and recreational trail riding**, where a mix of power and ruggedness is essential. The **F-series variants**, while more specialized, still retain **practical elements** such as **adjustable seats, removable windshields, and easy-access fuel tanks**, ensuring that they remain functional in both racing and everyday use.

In summary, the Arctic Cat 3604 series encompassing models like the **3604-300, 3604-472, F8, F6, F1000, F5 Twin Spar, and F570** represents a golden era of ATV engineering, where **innovation, power, and durability** converge to create machines that are as capable in the backcountry as they are on the racetrack. Whether you re seeking the **raw power of the F1000**, the **precision handling of the F5 Twin Spar**, or the **versatility of the 3604-472**, these ATVs deliver an unmatched riding experience that continues to captivate enthusiasts decades after their initial release. Built for those who refuse to compromise, the 3604 series remains a benchmark for off-road performance, blending **Arctic Cat s legendary heritage** with **cutting-edge technology** to produce ATVs that are as legendary as the riders who push them to their limits.
