Helical LSD

The MFactory 1.0/1.5 Way Metal Plate LSD is a high-performance limited-slip differential engineered to significantly enhance vehicle traction and power delivery. Constructed from Diamond-Cut Forged High-Nickel-Chromium-Molybdenum Steel, this differential ensures perfect fitment and finish for hassle-free installation and maintenance. It features advanced gear geometry designed to minimize parasitic drivetrain losses, with MFactory components typically transferring 1-2% more power to the ground compared to competitors. The differential is stress-tested on loaded dynos to withstand the shock loads of racing and the variable loads of daily driving. Its fully adjustable nature allows users to modify initial pre-load, engagement angles, and lock percentage without special tools, although transmission disassembly is required. The Metal Plate LSD requires regular maintenance, with replacement parts like pre-load springs and plates readily available at an affordable price. MFactory covers this LSD with a 1-year, globally transferable warranty for street, strip, or track use. This differential fits the BMW 3 Series E46 models from 1999-2006, including the 325i (M54 2.5L), 328i (M52 2.8L), and 330i (M54 3.0L).
