On the other hand, the Z71 package offers an eight-speed automatic transmission system. The benefit of the Z71 transmission is that it offers better performance and is more fuel efficient.

– Performance

The last difference to note is in terms of the performance offered by the two packages.

On the other hand, the Z71 package is the better option to consider if you want to drive your Chevrolet Avalanche off-road and with an exceptional level of performance.

Basically, the Z71 package prioritizes performance more than comfort. This is because it features better suspension and a powerful engine. It’s the best of both worlds and the option most people normally opt for.
