      Prism Supply Co. FAQ

      Are Prism Supply Co. parts made in the USA?
      Yes. Prism Supply Co. is a small shop outside Charlotte, North Carolina, founded by two brothers in 2012 to build handcrafted, American-made motorcycle parts. Most of the catalog is manufactured in-house rather than sourced overseas.
      What size petcock do I need for my gas tank?
      Petcock size depends on the thread pattern in your gas tank. Common options include 1/4-inch NPT, 3/8-inch NPT, 3/4"-18, and 22mm. Check your tank's existing petcock or threaded bung before ordering to confirm the correct size and thread pattern.
      Do Prism Supply Co. mid-controls fit both Sportster and Big Twin models?
      Fitment varies by product. Some Prism Supply Co. mid-control and mid-peg kits are designed specifically for Sportster models, while others fit Big Twin frames with Cone Shovelhead or Evo engines. Check the product listing to confirm compatibility with your motorcycle.
      What's the difference between a weld-on and bolt-on tail light mount?
      A bolt-on tail light mount attaches using existing hardware without modifying the frame or fender. A weld-on mount is permanently welded in place, which can provide a cleaner, more integrated look for a custom motorcycle build.
