In the world of automotive enthusiasts, accurate information is crucial. Unfortunately, Facebook groups often become a breeding ground for misinformation. One topic that frequently sparks confusion is determining whether an S10 truck has an eight and a half-inch rear end. However, with the right guidance, identifying the rear axle width becomes a simple task. In this article, we will provide you with an easy-to-understand guide to determining whether your S10 truck has an eight and a half-inch rear end, without even needing to look underneath your vehicle.
Identifying S10 Trucks with Eight and a Half-Inch Rear Ends
1. Chevrolet S10 ZR2
If you own a Chevrolet S10 ZR2, regardless of the year and whether it is a truck or a Blazer, it will have an eight and a half-inch rear end. This is a standard feature for all ZR2 models.
2. S10 Pickup and Two-Door Blazer with L35 4.3 Engine and Manual Transmission
For S10 pickups and two-door Blazers equipped with the L35 4.3 engine and a manual transmission, an eight and a half-inch rear end is the norm. However, there is one exception. In 1994, these vehicles required a 308 rear-end ratio in order to have the eight and a half-inch rear end. But for model years 1995 and newer, any stick shift L35-equipped S10 will definitely have an eight and a half-inch rear end.
3. Four-Door Blazer, Jimmy, and Bravada
If you own a four-door Blazer, Jimmy, or Bravada, you will have a seven and a half-inch rear end. This is because these vehicles did not have the option of the ZR2 package or the manual transmission, both of which come with an eight and a half-inch rear end. Therefore, all four-door Blazers, Jimmys, and Bravadas left the factory with a seven and a half-inch rear end.
4. S10 with 4.3 Engine and Automatic Transmission
S10 trucks equipped with a 4.3 engine and an automatic transmission do not come with an eight and a half-inch ring gear. The option for an eight and a half-inch rear end was not available as a standalone option. To have the eight and a half-inch rear end, your S10 would need to have the CR2 package or the L35 five-speed combination. There are no exceptions to this rule.
5. Rare and Desirable Configurations
If you are lucky enough to own a two-wheel drive Blazer with disc brakes, a five-speed transmission, and a G80 rear end, you have one of the most desirable rear ends available for your truck. This specific configuration, although rare, is highly sought after. If you come across one of these at a junkyard, grab it without hesitation.
Debunking Myths and Misinformation
It is important to rely on accurate information and not fall victim to false claims. Some individuals claim to have special order eight and a half-inch rear ends in their S10 trucks. However, this is simply not true. General Motors does not randomly install rear ends without purpose. Every configuration has a specific method and rationale behind it. Therefore, there were no special order eight and a half-inch rear ends for S10 trucks.
By following the guidelines provided in this article, you can easily determine whether your S10 truck has an eight and a half-inch rear end, without the need to inspect the underside of your vehicle. Understanding rear axle width is crucial for enthusiasts and owners who may wish to modify or upgrade their trucks. By having accurate information, you can confidently make decisions about your S10 truck’s performance. Remember, the key points to consider are the model and configuration of your truck, as well as the engine type and transmission. Stick to these guidelines, and you will be well-informed about your S10 truck’s rear axle width.
