20.75 CORE VARIOUS GM APPLICATIONS ALUMINUM RADIATOR (LS MOTOR SWAP, W/ BRUSHLESS FAN)<br><br>Made as an automatic (will fit both auto and manual) For manual, we can remove oil cooler, just inform us after or when ordering.<br><br>Item made to order in NY. Takes 2 weeks to complete build. Entire unit is ALL USA built.<br><br>This is a direct fit, bolt in replacement aluminum radiator for GM applications with a 20.75" core. Hose connection configured for a LS Motor Swap. This radiator is designed to allow the factory shroud to be bolted to it. Complete with 16" Spal Brushless fan, shroud, and electrical Kit. <br><br>Inlet: 1.375"<br> <br>Outlet:1.625"<br> <br>Direct fit radiator<br>6.5" thick<br>Full aluminum Shroud<br>16 Fins per inch<br>Filler neck is machined from a solid aluminum billet<br>No epoxy, fully furnace brazed<br>Fully TIG welded<br>100% MADE IN THE USA<br> <br>Radiator<br><br>The performance...<br><br>This radiator is built with a true high performance core made with 2 rows of 1? tubes, providing you with a core that is 2.25? thick. The tubes are spaced on 3/8" centers to maximize the total number of fins and tubes over the width of the radiator. As if that wasn?t enough we?ve gone one step further, each fin has been beautifully outfitted with 57 louvers to dramatically increase the heat transfer capabilities of each fin. This is in comparison to competitors cores that typically range from 26-42 louvers per fin, and in some cases... dimple fins... instead of louvers which is substantially less capable of dissipating heat.<br><br>In applications with an internal transmission oil cooler our engineers have replaced the standard ?cylindrical style? of oil cooler with a new state of the art high performance 7-plate style of cooler in order meet the heat transfer demands of your new performance transmission. In addition to the heat transfer benefits of this new transmission cooler this cooler is far less prone to leaks than the cylindrical style and can handle substantially greater pressures.<br>The shroud...<br><br>Our engineers have cleverly developed a new two chamber shroud. The first chamber properly and cleanly funnels the air from the core to the fans. The second chamber properly positions the leading edge of the fan with the backside of the primary chamber to reduce air turbulence in the primary chamber which.

Keep in mind you are considering a true high performance radiator with a thick core, a high fin count and a high tube count. All of that mass that is in front of the fans will create a certain amount of resistance, now if you add additional coolers to the front of the radiator you will be adding airflow resistance and you will be preheating the air before it gets to the radiator. The brushless fans are monsters, they will do a better job than anything else on the market to ensure that you are still getting the highest performance from your radiator regardless of what you stick in front of them.<br>
