*** Inlet and Outlet hose ends show on photo for representative purposes. Fittings must be purchased separately ***
While there is no specific size to use with a particular swap, a good general rule of thumb
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. Please reference Related Parts & Kits for fitting options based on your engine swap needs.
