Ordered produt for my 2015 GMC Sierra Denali 2500HD Duramax. They look great, built VERY strong. Passanger size fits perfect as advertised. The drivers side is a disaster installer spent day tryin to line up. Still not even! Called Amp, they said truck frame not straight from factory! Really?? What kind of answer is that?? Also have painted trim around wells that had to be trimed. Not happy! VERY EXPENSIVE! Would care about $$ if they were straight! I would NOT recommend this product.
