The Speedmaster PCE204.1028 TorqueWorm Helical Gear Limited Slip Differential is engineered for Dana 30 axle applications with a 27-spline axle configuration and is compatible with gear ratios of 3.73 and numerically higher. The helical gear design delivers smooth, progressive torque transfer between wheels without the jerky engagement associated with traditional clutch-style differentials, making it an ideal upgrade for improved traction on and off the road.
This drop-in limited slip unit is designed to maximize available traction by continuously biasing torque to the wheel with the most grip, reducing wheel spin during acceleration and challenging driving conditions. Built under the Speedmaster brand and intended for Dana 30 axle housings, this LSD is a straightforward performance upgrade for enthusiasts looking to enhance drivability and traction without sacrificing street manners.
