The 1968-1977 GM A-Body with LS Swap Aluminum Performance Dual Flow Radiator and 14 Inch fan kit is meant to be used with an external trans cooler.
When you need the best and biggest, look no further than the Cold Case Super Duty Line.
All Super Duty kits include radiators with 2 rows and 1.25 Inch tubes, aluminum fan shroud, and dual 14 Inch fans, flowing at 2200cfm per fan!
For extreme horsepower applications OR if you just want the best of the best...
These COLD-CASE radiators are 100 percent aluminum and Tig welded, and absolutely beautiful.
Don't buy a 3 or 4 row aluminum radiator!
It doesn't cool as good as these oversize 2 row models.
These radiators have the correct stamping and are original appearing.
Once painted, you'd be hard pressed to find a difference over an original versus a COLD-CASE.
