Product Questions & Answers

Q:Do these come with the caps that hide the actual bracket?
Rick r.
A:BEST ANSWERHi Rick, There is no mention of the caps for the brackets on our system. It would be best to call the manufacturer (Dee Zee) about part number DZ15340. Their telephone number is 1-800-779-2102. Show less

Q:Would these brackets fit a sierra 1500 and make the steps closer to the ground? Show Less
Tim H.
A:BEST ANSWERHi Tim, I'm glad to assist you. No, it is not compatible with your original running boards that came with your car. We do not carry factory running board brackets replacement for most of the truck models. Show less
