CURRIE SUPER SPORTSMAN THIRD MEMBER - 3.70 GEARS - 31 SPLINE CURRIE TWINTRAC - ALUMINUM DAYTONA PINION SUPPORT - 1350 CHROMOLY YOKE

The Currie Enterprises CE-9CT370S50 is a Ford 9-inch Sportsman Series Complete Third Member Assembly, built-to-order for 31-spline axles. This assembly features a 3.70 gear ratio and a Twin Trac differential, which is a helical gear limited-slip differential (HGLSD) type. The design includes a rigid nodular iron gear case and a nodular iron Daytona big-bearing pinion support to minimize gear deflection and enhance durability. The assembly utilizes high-quality Motive Gear Performance series ring and pinion sets, along with premium Timken or Koyo bearings and high-performance seals for long-lasting performance. It also includes a 1350 Series yoke. This part is ideal for street rods, muscle cars, or trucks requiring a new gear ratio or performance differential. It is fully assembled in-house by skilled professionals. The manufacturer recommends using a severe-duty 85w-140 non-synthetic gear oil with an API GL-5 rating for lubrication.
