The width of a S10 rear end varies depending on the year and model of the vehicle. Generally speaking, most standard S10 models have a 56 inch wide rear end, while extended cab models may be up to 67 inches wide. The S10 Blazer has an even wider rear end at 68 inches across.
Depending on what type of wheels are installed, there may be some additional width added due to wheel offset or backspacing. If you are unsure as to how wide your particular S10 is, it’s best to measure from one wheel mounting surface to the other in order to get an exact measurement for your specific vehicle.
The rear end of a S10 is pretty wide, measuring just over 60 inches at its widest point. This makes it an ideal choice for those looking to make their truck wider and more stable in the back. The width also allows for larger tires and wheels, allowing your ride to look even more aggressive on the road!

How Wide is a 1997 S10 Rear End?
The rear end width of a 1997 S10 is typically 59.5 inches, which marks the distance between the wheel mounting surfaces on either side. This measurement is important to know when replacing axles or installing wheels and tires because it determines how far apart the hubs are from each other.
It also helps you decide what size differential cover you need for your vehicle, as well as any aftermarket parts such as air bags or traction bars that may be installed in order to improve handling and performance.
Additionally, this width will determine what type of leaf springs are needed if your vehicle has a live axle setup, so measuring it properly beforehand can save time and money when it comes time to upgrade components later on down the road.
How Wide is a Chevy 10 Bolt Rear End?
The width of a Chevy 10 bolt rear end can vary depending on the model, but generally speaking it measures 9.3 inches across the axle flange and 12.2 inches at its widest point (including wheel studs). The 10 bolt is most commonly found in Chevy/GMC trucks from 1973-1998 as well as some classic muscle cars such as Camaros and Chevelles from 1964-1972.
It’s considered to be one of the strongest rear ends for its size, making it an ideal choice for those looking to upgrade their vehicle with a little extra strength without having to make major modifications or invest in more expensive aftermarket parts.
In terms of performance, this rear end is capable of handling up to 600 horsepower with some minor upgrades like hardened axles and heavy duty bearings which makes it perfect for drag racing applications or any other type of high performance driving you may have planned for your car.
What is the Diameter of an S10 Axle?
The diameter of an S10 axle is 5.625 inches, which is the same as that of a full-sized Chevy truck. This makes it possible to use common parts and accessories from standard GM trucks on your S10. It also means that you can swap axles between different models and generations of trucks without worrying about compatibility issues.
For example, if you have an older model S10 with a worn out axle but still want to keep driving it, you can simply install an axle from a newer model instead of having to find one specifically made for your vehicle’s year and model. The fact that they all share the same 5.625” diameter makes swapping them between vehicles easy and cost effective!
What Year S10 Has a 8.5 Rear End?
The 8.5 rear end was introduced in the Chevrolet S10 pickup truck line for the 1991 model year, and remained until 2004 when it was replaced by an 8.6 inch axle. This change came about due to a larger diameter ring gear which provided improved strength and durability over the smaller 7.625 inch axle that was used prior to 1991.
The increased size of the axle also allowed for more power handling capability, making it a popular choice among those who used their S10s for off-road or hauling applications.
It is important to note that not all trucks from this era had an 8.5 rear end installed as some were equipped with either 7 5/8″ or even 9 1/4″ axles depending on factory optioning at time of purchase – so be sure to check your vehicle’s VIN number before ordering any components related to changing out rearends!
