The answer is Yes and no. The back pair fit perfectly, the front set fits as well but are about 6 inches shorter on the front than the factory 1500 flares. They come down to the line just below your headlamps.

 

Which fit great on a 1500 sport. There is a guy on here with this exact setup on a mineral grey 1500 sport. The way the sports bumper facia comes up by the fender/ headlights looks good with the 2500 flares

 

front come in 2 lengths
short one for those with chrome bumpers
long ones for the painted plastic sports style

so if you have the chrome bumper & so do they, you are set
the short ones should fit with the sports style bumper too, they just won't reach the bottom of the bumper

both types, so you can view the difference, if i can bring the pix up

if you have a sport 1500 get 2500 fender flares, if u dont have a sport , get the 1500 hers mine. i have the 2500 fender flares

 

They would be equally as good on the express model as well as the sport
