OS Giken Mazda Miata NC (MT Only) Super Lock LSD

OS Giken is well-known for making high-performance drivetrain components, and their Super Lock Limited Slip Differential (LSD) for the 2006-2014 Mazda MX-5 Miata (NC generation, manual transmission only) is a prime example. If you're looking to significantly improve your Miata's traction and handling, especially during spirited driving or track use, this LSD is a solid option. It's designed to put power down more effectively, reducing wheelspin and allowing for more controlled acceleration out of corners.

What sets the OS Giken Super Lock LSD apart is its advanced internal design. It utilizes a unique multi-plate system that can lock up to 100% under acceleration and deceleration, providing a very direct and predictable feel. Unlike some other LSDs that can be grabby or noisy in daily driving, OS Giken's design aims for a smooth engagement, making it a more comfortable choice for a street-driven car that also sees track time. The internal components are made from strong, well-built materials designed for durability under demanding conditions. This unit is specifically engineered for the manual transmission MX-5 Miata, ensuring a direct fit and optimal performance for that application.

When installing this LSD, it's important to note that it replaces your factory differential. This is a significant upgrade that requires professional installation or a mechanic with experience in drivetrain work. You'll want to ensure you have the correct gear oil for break-in and ongoing use as recommended by OS Giken. The result of this installation is a much more capable and engaging driving experience, allowing you to put the power down more effectively and confidently.
