Griffin Radiators

What you need to know about Aluminum Radiators

Whatever your need – radiators for racing, street rod, classic, muscle, exotic or late model cars and trucks – Griffin has your radiator in inventory or can build it to your exact specifications. Griffin is the only manufacturer that maintains templates of virtually every car or truck, make and model. Your Griffin radiator is truly a performance radiator, not an adaptation of an OEM product. In most cases it is a direct fit, bolt-in replacement that is made to fit your vehicle, although sometimes requiring modifications due to core thickness.

Why Aluminum Radiators ?
{Also see > > > Griffin Radiator FAQ's (all the questions customers ask . . . well most any way)}

4 Core Copper Brass - vs - 2 Core Aluminum

Seen in example A is a copper brass core cross section using 1/2" tubes. Much of the cooling efficiency is lost because of the limited amount of tube-to-fin contact. Seen in example B is an aluminum core cross section using 1" tubes. Since the aluminum tube is a minimum of 1", the efficiency of the tube-to=fin contact is much greater. In fact a two row 1" tube radiator has 40% greater tube-to-fin contact over a 4 row copper brass radiator (this can be seen in the examples above by a comparison of the measurement B) Therefore the cooling efficiency is increased by 25% over that of a copper brass core.
Aluminum radiators are also 60% lighter than the same copper brass radiator.
