The 73-87 C10 12 Bolt Rear End: An Essential Upgrade for Your Truck

As a proud owner of a 73-87 C10 truck, I can attest to the importance of having a 12 bolt rear end installed. This upgrade not only improves the overall performance and handling of your truck, but it also provides a much-needed durability boost.

My Buying Guide on ’73-87 C10 12 Bolt Rear End’

I am a proud owner of a ’79 Chevy C10 and one of the most important components of my truck is the rear end. After much research and personal experience, I have put together this buying guide for anyone looking to upgrade or replace their ’73-87 C10 12 bolt rear end.

Understanding the Basics

Before diving into the buying process, it is important to understand what a rear end is and its function in your truck. The rear end, also known as a differential, is responsible for transferring power from the engine to the wheels. It allows for smooth turns by allowing one wheel to rotate faster than the other when making a turn.

Identifying Your Needs

The first step in buying a rear end for your C10 is identifying your specific needs. Are you looking for an upgrade for better performance or do you need a replacement due to wear and tear? This will help narrow down your options and ensure you are getting the right product for your truck.

Considerations

When shopping for a ’73-87 C10 12 bolt rear end, there are several factors to consider:

1. Gear Ratio: This determines how many times the driveshaft rotates for every revolution of the wheels. A higher gear ratio means better acceleration but lower top speed, while a lower ratio provides better gas mileage but slower acceleration.

2. Axle Type: The most common axle type for C10 trucks is the semi-floating axle. However, if you plan on towing heavy loads or off-roading, consider upgrading to a full-floating axle.

3. Material: The two most common materials used for rear ends are cast iron and aluminum alloy. Cast iron is heavier but more durable while aluminum alloy is lighter but may not withstand heavy loads as well.

4. Brand: There are many brands that offer aftermarket rear ends for C10 trucks such as Moser Engineering, Eaton, and Strange Engineering. Do some research and read reviews to determine which brand offers the best quality and performance.

Budget

It’s important to have a budget in mind when shopping for a new rear end. Prices can range from $500-$2000 depending on brand, material, and features. Keep in mind that investing in a high-quality rear end will save you money in the long run by avoiding frequent replacements.

Installation

Unless you have experience with mechanics, it is best to have a professional install your new rear end. Improper installation can lead to serious damage or even accidents while driving.

Conclusion

The ’73-87 C10 12 bolt rear end plays an important role in the performance of your truck. By understanding your needs, considering all factors, setting a budget, and ensuring proper installation, you can find the perfect rear end that will enhance your driving experience with your beloved C10 truck.
