  • 4.8L GM LS Engine 1.25" inlet (FB400), 1.50" outlet (FB401)
  • 5.3L GM LS Engine 1.50" inlet (FB401). 1.50" outlet (FB401)
  • 5.7L GM LS Engine 1.50" inlet (FB401), 1.50" outlet (FB401)
  • 6.0L GM LS Engine 1.50" inlet (FB401), 1.75" outlet (FB402)
  • 6.2L GM LS Engine 1.50" inlet (FB401), 1.75" outlet (FB402)
  • 7.0L GM LS Engine 1.75" inlet (FB402), 1.75" outlet (FB402)

This again only serves as a guide and any size fitting can be utilized with any LS-Swap Radiator. Our Frostbite LS-Swap Series Radiators do not come with Inlet and Outlet fittings.
