Choosing a liner

Sierra 2500 HD floor liners hold what boots bring

An HD Sierra spends its days somewhere muddy, and the argument for a deep-channel floor liner is simply that it holds what comes in on a boot instead of passing it into the carpet. Crew cab fitment covers most of them. 8 options fit.
