So, what are the differences and similarities between SLT and SLE?

The Similarities

SLT and SLE share many features despite being different trim levels. In fact, they are sometimes not easy to distinguish if you are not familiar with truck features.

Under the hood, SLE and SLT trims come with the same engine. This is especially true when comparing GMC Sierra 2500HD and 3500HD SLT and SLE trims. They both have a 6.6-liter V8 engine. However, some SLT trims have more powerful engines.

Another similarity is in the towing package. Both SLT and SLE GMC trucks come with similar features for towing.

SLT and SLE also share modern features only found on premium cars, including cruise control systems, power-adjustable seats, reversing cameras, heated front seats, premium audio systems, etc.

The Differences

The most visible difference between SLT and SLE trims is the price tag. As expected, SLT is more expensive because of the additional luxury features that enhance the comfort of your ride.

Also, SLE trims are generally fitted with smaller wheels than SLT trims. This is true for most GMC truck models listed in this article. SLT trims often come equipped with more stylish and bigger wheels with better rim accents.

Another difference is in the interior. This, however, does not apply to all models. Most SLE trims have a cloth interior, with a few featuring leather seats. On the other hand, SLT trims have leather as a factory standard.

You can also notice that SLT trims have a hands-free power liftgate and LED fog lamps.
