Scott T.
A:BEST ANSWERHi Scott, thank you for reaching out! This set only consists of the bars that go across the bed from left to right. You can click the link below to order the set while stocks last. Do not forget to check the part's fitment to your vehicle before checking out. You can also provide your truck information if you need help finding the matching side rails. Have a great day! https://www.carparts.com/bed-rails/dee-zee/d37dz99799tb?can=cpab2020_csqa_202406018 Show less
