[6] PopMatters writer Nikki Tranter proposed that the lyrics of the song saw singer Miller "relating his band's vision for its future", citing lines such as "A simple sound/A heavy side/Could win the whole world over".

Billboard magazine said that it contained "enough unique elements to raise [the band] above the competition",[4] while Tranter of PopMatters described it in the same category as "Escape from Hellview" and "Frenetic Amnesic" as a "neat heavy rock tune".

[7] Music website Loudwire ranked "Flesh into Gear" as the 35th-best hard rock song of the 21st century, with writer Graham Hartmann claiming that it "barely scratches the surface in regard to the band's accomplishments in both importance and creativity".

[11] The music video for "Flesh into Gear" was directed by Bam Margera, brother of drummer Jess, and released in the week of December 23, 2002.

[13] Writing a review of the album for the website The Movies Made Me Do It, Chad Connolly quoted director Margera as noting that the video was filmed on an "extremely low budget", and described it as a performance video interlaced with stunt clips featuring CKY crew members Brandon DiCamillo, Rake Yohn, and Margera.
