When it comes to choosing the right differential for your vehicle, the options can be overwhelming. One of the most common differentials is the 10 bolt, which is available in two variations: the 8.2 and the 8.5. In this article, we’ll take a closer look at these two options to help you make an informed decision about which one is right for your needs.

8.2 vs 8.5 10 bolt Differentials: Key Differences
The primary difference between the 8.2 and 8.5 10 bolt differentials is their size. The 8.2 has an 8.2-inch ring gear diameter, while the 8.5 has 8.5-inch ring gear diameter. While this may seem like a small difference, it can have a significant impact on the strength and durability of the differential.
Strength and Durability
The larger ring gear diameter of the 8.5 10 bolt differential provides a stronger and more durable option than the 8.2. This is because the larger ring gear provides more teeth engagement, which distributes the load more evenly across the gears. Additionally, the larger ring gear can handle more torque and horsepower than the 8.2, making it a better option for high-performance applications.
Size and Weight
While the 8.5 10 bolt differential is stronger and more durable than the 8.2, it is also larger and heavier. This can be a consideration if you are looking to reduce weight in your vehicle or if you have limited space in your differential housing. The 8.2 is a more compact and lighter option, making it a better choice for some applications.
Gear Ratio Options
Both the 8.2 and 8.5 10 bolt differentials are available in a variety of gear ratio options. This allows you to choose the gear ratio that best suits your needs, whether you are looking for improved acceleration or better fuel efficiency. However, it is worth noting that some gear ratios may not be available for both the 8.2 and 8.5 differentials, so it is important to check availability before making your decision.
Aftermarket Support
Another factor to consider when choosing between the 8.2 and 8.5 10 bolt differentials is aftermarket support. While both differentials have a wide range of aftermarket parts available, the 8.5 has a larger aftermarket support due to its popularity and durability. This means that you may have an easier time finding replacement parts or upgrades for the 8.5 differential.
Pros and Cons
Now that we’ve discussed the key differences between the 8.2 and 8.5 10 bolt differentials, let’s take a closer look at their pros and cons.
8.2 10 Bolt Differential Pros:
- Compact and lightweight
- Available in a variety of gear ratios
- Can be a more affordable option
- Suitable for lower horsepower and torque applications
8.2 10 Bolt Differential Cons:
- Not as strong or durable as the 8.5
- Limited aftermarket support
8.5 10 Bolt Differential Pros:
- Strong and durable
- Can handle the high horsepower and torque
- Wide range of gear ratio options is available
- Larger aftermarket support
8.5 10 Bolt Differential Cons:
- Larger and heavier
- More expensive than the 8.2
- May not be suitable for all applications

To help you compare the key features of the 8.2 and 8.5 10 bolt differentials, we’ve created a comparison table:
| Feature | 8.2 10 Bolt Differential | 8.5 10 Bolt Differential |
| Ring Gear Diameter | 8.2 inches | 8.5 inches |
| Strength and Durability | Less Strong and Durable | Strong and Durable |
| Size and Weight | Compact and Lightweight | Larger and Heavier |
| Gear Ratio Options | Available in a variety of gear ratios | Wide range of gear ratios available |
| Aftermarket Support | Limited | Larger aftermarket support |
| Cost | More affordable option | More expensive than 8.2 |
| Suitable for | Lower horsepower and torque applications | High horsepower and torque applications |
Conclusion
In conclusion, choosing between the 8.2 and 8.5 10 bolt differentials depends on needs and requirements. If you’re looking for a more affordable and lightweight option that can handle the lower horsepower and torque applications, the 8.2 may be the right choice for you.
However, if you need a stronger and more durable differential that can handle the high horsepower and torque, the 8.5 is the way to go. Keep in mind that the 8.5 is also larger and heavier, so it may not be suitable for all applications.
