Chevy Avalanche vs Silverado: which Chevrolet is better?

When it comes to American-made heavy-duty off-road capable pickup trucks, the Chevrolet Avalanche and the Chevrolet Silverado are two very well-known names.

Manufactured by General Motors-owned Chevrolet, both these trucks gained popularity in the American and International markets as rugged offroad utility vehicles that are also capable of towing heavy loads while maintaining good performance.

However, there are advantages and disadvantages to owning these trucks which we’ll discuss in detail as we go on.

Avalanche vs Silverado: which one is better?

One of the most important differences between these trucks is the fact these tracks have very different frame types.

The Avalanche has a unibody structure. This means that the body and the chassis of the vehicle are manufactured as a single piece and cannot be separated from each other.

On the other hand, the Silverado has a body-on-frame body type. This means that the body or frame of the car is a separate piece that is mounted on the chassis of the car.

When you look at the differences between these two vehicles, all of those differences eventually boil down to their body types.

Chevy Avalanche: Short Overview

The Avalanche debuted in 2001 and was manufactured in two generations.

The first generation ran from 2001 to 2006. During this time, the truck came with a Vortec 5.3L V8 option or a Vortec 8.1L V8 option, both options were accompanied by variations of the same 4-speed automatic transmission.

The second generation started hitting the markets from 2007 all the way to 2013. During this time, the approach towards the chassis remained the same. An upgraded version of the Vortec 5.3L V8 was offered, and models from 2009 also came with a 6.0L V8 option.

Unlike the first-gen, the second-gen came with a 6-speed automatic option besides the already existing 4-speed automatic.

Unfortunately, the Avalanche was discontinued by Chevrolet from 2014 onwards.

About Silverado: Short Overview

The Silverado is one of Chevy’s oldest running models that is currently still in production. Debuted in 1999, the Silverado has seen five generations of iterations with a wide range of models as well as engine and transmission specs.

As a result, there is an enormous number of combinations of Silverado trucks that can still be found on the streets.

In the 20+ years of production, the Silverado came with a huge number of engine and transmission options. Aside from the 4.3L V6, the majority of the options were V8 engines with displacement ranging from 4.8L all the way to 8.1L V8. Some of the later generations also had a Duramax Diesel engine option.

In terms of transmission, the Silverado came with a 4-speed automatic, 5-speed automatic, and manual as well as 6-speed automatic and manual.

Additionally, plans to manufacture a fully electric version of the Silverado are already in place with the concept fully developed.

Amenities	Reversing camera, parking sensor, heated seats, media system	N/A	The Avalanche is more luxurious.

Before we dive deeper into the comparison, we need to set some standards. As the Avalanche was last manufactured during the 2012-2013 period, we’re comparing an Avalanche of that time period with a Silverado of the same period.

In order for more consistency, we’re making the Avalanche vs Silverado comparison based on models that have similar cab styles as well as engine and transmission. For this comparison, we chose the 4WD Crew Cab with the Vortec 5.3L V8 FlexFuel engine.

Comparing Avalanche vs Chevrolet Silverado, even though they’re manufactured by the same company, their purpose is very different. Whereas the Avalanche focused on utility and comfort, the Silverado mainly focuses on utility.

Body type:

Firstly, the Avalanche has a unibody structure, meaning that the body and chassis of the car are built as a single piece and cannot be separated. This means that the Avalanche had better ride quality.

Unlike the Avalanche, the Silverado came with a body-on-frame structure, which meant that the body was a separate piece that was mounted on the chassis. Therefore, it was possible for the body to have a wide range of combinations, as the body was built separately from the chassis.

Because of its structure, the Silverado can carry a lot more weight and handle a lot more structural stress on its body. This makes it the ideal choice for towing and carrying.

Repair Cost:

As the Avalanche has a unibody structure, any significant damage to the body also indicated serious damage to the chassis. Therefore, the repair of such damage was very expensive. On the other hand, any damage to the body of the Silverado mostly kept the chassis unharmed as they were separate pieces.

As a result, the Silverado is better when it comes to the cost of repair and maintenance.

Bed Length and Cargo Volume:

When it comes to the size of the load that can be carried in the bed, the Silverado can be considered the winner. The Silverado’s bed is considerably longer than the Avalanche. Moreover, it has a higher height and width, giving the cargo space more volume compared to the Avalanche.

However, the bed size of the Avalanche can vary depending on the midgate. Basically, the back wall of the Avalanche’s cab can be removed and the rear seats can be folded down. In this way, the bed can be extended to where the back row would be. Doing this increases the bed length as well as carrying capacity hugely, however you do lose the back row seating in the process.

Interior Space

In terms of space inside the cab, we can say that the areas are very similar in size. However, a little bit of extra legroom can make a huge difference. The Silverado offers almost an inch more of added legroom, which definitely increases the comfort level within the cab. Thus, the Silverado is clearly the winner in this category.

Payload and Towing Capability

As mentioned earlier, the body-on-frame structure of the Silverado allows its chassis to carry a lot more weight, and this idea is supported by the official data provided by Chevrolet.

We can see that in excluding the towing, the Avalanche can carry a maximum of 1263 lbs whereas the Silverado can carry around one and a half times that at 1890 lbs.

The same trend continues when we look at their hauling capabilities, where the Silverado can carry an enormous tow of over 10000 lbs whereas the Avalanche tops off at about 8000 lbs.

Therefore, the Silverado is a much better load carrier and hauler.

Suspension and Ride Quality

Even though the front suspension is similar on both of these trucks, the rear suspension is more suited to their individual purposes.

As the Avalanche focuses on comfort and rides quality, its rear suspension consists of coil springs with dampening capabilities, ensuring a much smoother ride for its passengers. The dampening capabilities allow the vehicle to be better at off-roading as well.

On the other hand, the Silverado’s rear suspension has traditional leaf springs. This is mostly because leaf spring suspensions can carry a lot more weight on them. However, these suspensions do compromise a lot on ride quality, making the ride stiffer.

In this case, the suspension of the Avalanche is clearly superior.

Amenities and Luxuries

As the Avalanche was more focused on comfort, it came with a higher amount of comfort amenities. On the other hand, the Silverado was built more as a utility vehicle thus skipping on amenities was done to save cost.

However, as the Silverado had a wide range of options, there were trim levels available with more luxuries.

Avalanche and Silverado Similarities

There are a lot of similarities when you’re considering Avalanche and Silverado. This is because they are manufactured by the same company.

Both of these models have a lot of parts in common, as they helped Chevrolet reduce the cost of manufacturing and research & development. As the parts were similar, the cost of maintenance for consumers was also very low for both these trucks.
These trucks share the same group of transmission. But as the Silverado has a lot more trim levels, it comes with additional transmission options. The most common across both these models was the Hydra-Matic 6L80 six-speed automatic.
These trucks had a lot of engine options in common. Some of the more popular engine options include the Vortec 5.3 L V8 and Vortec 6.0L V8.
Both vehicles had four-wheel disc brakes accompanied by ABS.
Both vehicles had independent coil-over suspensions at the front.
Both trucks had similar performance in terms of power and torque output.
Both trucks had similar mileage in cities and highways.

Both the models have very similar fuel economy as well as seating arrangements. Most importantly, as they are manufactured by the same company, they share a lot of parts and components which makes manufacturing and maintenance cheaper.
