▶ Vehicle Fitments
The OS Giken Super Lock Limited Slip Differential is a high-performance drivetrain component designed for Subaru WRX STi models from 2004 to 2014. Engineered with an innovative design, it features the capacity to house up to 28 friction plates, enabling exceptional locking capabilities. The patented lock timing system ensures a progressive, smooth, and quiet lockup, which enhances handling precision and reduces drivetrain noise. This LSD is built for enthusiasts seeking quick lap times, consistent performance, and reliable tuning adjustments. Its robust construction and advanced friction plate technology deliver improved traction and stability during aggressive driving or track use, making it a top choice for performance-oriented applications.
Designed specifically for 2004-2014 Subaru WRX STi GD/GR models, this Super Lock LSD is a direct replacement for the factory differential. It is suitable for street, track, or rally use where maximum locking performance is desired. Installation involves replacing the stock differential with this bolt-on upgrade, providing an immediate performance boost without extensive modifications. The kit includes the differential assembly with all necessary friction plates and components for installation. Compatible with the vehicle's existing drivetrain, it offers a reliable upgrade for drivers seeking enhanced cornering, reduced wheel spin, and improved overall handling in demanding driving conditions.

Overview
Overview
Super Lock Limited Slip Differential by OS Giken
The OS Super Lock LSD is the culmination of over four years of extensive research and development leading to a revolutionary LSD design. With the capacity to house an unprecedented number of friction plates (up to 28 plates in total) and combined with our patented lock timing system, the Super Lock LSD is able to achieve complete lock in a progressive, smooth, and quiet manner. This effort translates to quick lap times and repeatable tuning and performance.
Features
- Miniaturized pressure ring and a superior spline-through-side-gear design allows for fitment of more friction plates (up to 2x as many as competitors versions), offering true 100% lock capability.
- Patented pressure ring design allows for smooth, progressive locking.
- LSD case has a relief cut-out for the cone spring, resulting in minimal cone spring degradation and enhanced durability.
- All components are chemically heat treated for maximum durability
- LSD case is machined from a single billet piece to ensure uniformity.
- Initial torque can be adjusted by using thicker / thinner cone springs
- Lock progression timing can be adjusted by using stiffer / weaker pressure ring springs, allowing the progression of full lock to be fine-tuned to the vehicle/driver.
- Ramp angles can be customized by swapping the pressure ring and iron cross for even more tuning possibilities.
- TCD spec disks can be installed for increased oil cooling and even smoother operation.
