Hello Fernando,

Thanks for writing in!

For the Westin HDX Nerf Bars with Drop Steps # W49XQ on your 2021 Chevy Silverado 1500, you need the Replacement Mounting Hardware Kit for Westin HDX 4" Nerf Bars with Drop Steps # 56-14135PK. This kit includes the replacement brackets and mounting hardware needed to get your nerf bars installed.

Did you get a good deal on some used ones, or transferring them over and lost the hardware?
