Speedway SBC Universal Double-Pass Aluminum Radiator
This double pass radiator works well for oval track racing applications where maximum efficiency is needed. The double-pass design offers a 5° to 20° coolant temperature drop versus a standard, single-pass radiator with equal core size.
100% all-aluminum construction. The furnace-brazed core increases durability compared to other radiators with epoxy-glued or crimped-gasket sealing methods. Two rows of 1" aluminum tubes allow this radiator to out-cool a similarly sized radiator with five rows of copper tubes. A rugged billet aluminum filler neck with screw-in bleed is also included.
All-aluminum, furnace-brazed construction
No cheap epoxy glue or crimped in gaskets
Maximum amount of fins per inch allows greater heat transfer
