Supercharger rear intake and discharge manifold porting for 99-03 Chevy or GM Whipple or Lysholm Supercharger passenger side mount. The rear manifold is very restrictive for side mounted 2300AX/AXO superchargers on a 99-03 Chevy or GM LS truck engine. JB Performance will fully port match the rear to the rear port shape of the 2300AX/AXO and remove material for better air flow. Discharge manifold is ported to allow more air with less restriction.
Please note that there is an extra fee for disassembly and assembly when not combined with a rebuild. We cannot guarantee the condition of any consumable components with supercharger porting services. Remember, this is port work, not a rebuild. If you wish to have it rebuilt, please choose this service when the item is sent in, so that it can be handled by the correct department. See rebuild section on rebuild pricing and information.
