A Limited Slip Differential (LSD) is a type of differential that improves traction by limiting the slip between the drive wheels. Unlike an open differential, which can send all power to one spinning wheel, an LSD distributes torque more effectively—especially during hard acceleration, cornering, or uneven terrain. LSDs are essential in motorsport, off-roading, and high-performance street applications.
As the global automotive market shifts toward performance upgrades and advanced drivetrain systems, the LSD industry is experiencing significant growth. From amateur tuners to OEM manufacturers, demand for high-quality LSDs is rising across all segments. This surge is fueled by increased motorsports participation, the growth of car customization culture, and a broader interest in performance vehicles. Whether it’s track racing, drifting, or off-road challenges, LSDs have become a critical component for drivers seeking control and efficiency.
In this guide, we’ve compared LSD manufacturers from around the world and selected the top 10 most recognized based on their global popularity, reliability, technological innovation, and proven performance. It’s designed to help LSD buyers, performance tuners, and automotive professionals find the most trusted brands available in 2025.
