Product Note: 2019 Silverado/Sierra 1500

2019 is a transition year for GM. They produced a new body style for the Chevy Silverado/GMC Sierra 1500, but they also continued the "Old Body Style" (really 2018 body style) for the 2019 Silverado/Sierra 1500 as well. This accounts for both the 5'7" (short) and 6'4" (standard) and 8' (long) bed lengths. There is no body style update for the 2019 2500/3500 GM trucks. 

The 2019 "Old Body Style" Silverado/Sierra 1500 takes a different DECKED system than the new body style 2019 Silverado/Sierra 1500.

The three most significant visual differences between the "Old Body Style" and the new body style are the fenders, headlights and exhaust:
 

1). FENDERS: The "Old Body Style" 2019 Silverado 1500 is boxy around the fenders. The new 2019 Silverado 1500 is "swoopy" around the fenders.

 

2). EXHAUST:  The "Old Body Style" 2019 Silverado 1500 has a regular exhaust. The new 2019 Silverado 1500 has a fully branded tailgate and incorporated split dual exhaust tips.

 

3). HEADLIGHTS:  See images below.
