Proform Brass Freeze Plug Kits
Water expands when it turns to ice, and if the coolant in your vehicle doesn't have enough antifreeze protection, it can freeze and then crack the engine block. Proform freeze plugs are designed to pop out under such conditions to relieve the pressure on the block. Unlike standard steel freeze plugs, Proform Brass Freeze Plugs resist corrosion better for longer lasting engine protection. These kits include all the necessary freeze, cam, and oil galley plugs for one complete engine block. Made in the USA!
