What Should You Consider When Choosing Rear Axles for Big Tires on the Grizzly 700?
When choosing rear axles for big tires on the Grizzly 700, consider the axle strength, gear ratio, weight capacity, and material composition.
- Axle strength
- Gear ratio
- Weight capacity
- Material composition
- Compatibility with aftermarket tires and accessories
These factors will influence performance and reliability, impacting your choice of rear axles.
-
Axle Strength:
Axle strength refers to the ability of the axle to withstand the stresses and strains of off-road use, especially with larger tires. A stronger axle reduces the risk of breakage. Upgrading to heavy-duty axles can enhance strength. According to a study by ATV Action in 2020, stronger axles improve performance in rugged terrains. -
Gear Ratio:
Gear ratio affects the torque and speed of the vehicle. A lower gear ratio is beneficial when using big tires. It helps in maintaining power and acceleration. For optimal performance, choose a gear ratio compatible with the larger tire diameter. Many enthusiasts recommend a ratio of 28:1 to ensure balance between speed and torque. -
Weight Capacity:
Weight capacity indicates how much load the axle can handle. Upgrading to larger tires generally increases overall weight. A higher weight capacity helps in maintaining stability and safety. According to a report by Off-Road Magazine in 2021, choosing axles with a weight capacity exceeding the vehicle’s total weight is crucial for durability. -

Why Are 4×4 Axles Necessary for Handling Big Tires on a Grizzly 700?
4×4 axles are necessary for handling big tires on a Grizzly 700 because they provide the required torque and stability for off-road performance. These axles also distribute power evenly across all four wheels. This is especially crucial when navigating rough terrains or steep inclines with larger tires.
The definition of a 4×4 axle can be referenced from the American Society of Mechanical Engineers (ASME). They describe a 4×4 axle as a drive system that allows all four wheels of a vehicle to receive power from the engine simultaneously, improving traction and control.
The underlying reasons why 4×4 axles are essential for larger tires on the Grizzly 700 include increased surface area and weight. Big tires have a larger footprint. This larger surface area enhances traction on varied terrains but requires more power to turn. The 4×4 axle system compensates for this increase in demand. Additionally, larger tires often add weight, which can affect handling and stability. The 4×4 setup ensures optimum power distribution to manage this added weight effectively.
When discussing technical terms, “torque” refers to the rotational force produced by the engine. It is crucial for moving the vehicle forward, especially when confronting uphill or rugged surfaces. “Traction” refers to the grip between the tires and the ground. Enhanced traction minimizes wheel slippage, ensuring the vehicle maintains control.
The mechanisms involved in 4×4 axles include the differential, which allows wheels to rotate at different speeds while turning. This is vital for maintaining stability and control, especially with larger tires that can alter the vehicle’s balance. The drive shaft transmits power from the engine to the axles, enabling all four wheels to engage simultaneously.
Specific conditions that contribute to the necessity of 4×4 axles include off-road driving and steep terrains. For example, when traversing rocky paths, a Grizzly 700 with larger tires may struggle without a 4×4 system, leading to reduced control and potential stuck situations. Similarly, during heavy mud or snow, the 4×4 axles provide the necessary traction and power, enabling the vehicle to navigate through challenging conditions with ease.
