What is the primary benefit of installing an OS Giken Super Lock LSD?

The main advantage is significantly improved traction and handling. The Super Lock design locks up almost completely under acceleration, putting power down more effectively and reducing wheel hop, while still allowing for smoother cornering when you're not on the throttle.

Does this LSD come with all the necessary installation hardware?

This product listing is for the OS Giken Super Lock LSD unit itself. It is recommended to consult the manufacturer's installation guide or a qualified mechanic to determine if any additional hardware or specialized tools are required for your specific vehicle's differential installation.

What type of fluid should I use with this differential?

Product Details

This OS Giken Super Lock Limited Slip Differential (LSD) is designed specifically for manual transmission Mazda RX-7 models from 1987-1991 and 1993-1995, as well as RX-8 models from 2004-2011. It's a well-built unit that replaces your factory open or clutch-type differential, offering a significant improvement in traction and handling, especially during spirited driving or track use. The Super Lock design is known for its ability to lock up almost 100% under acceleration, which helps put power down more effectively and reduces wheel hop.

What you get in this package is the OS Giken Super Lock LSD unit itself, ready for installation into your RX-7 or RX-8's rear end. The unique design of the Super Lock LSD uses a special cam mechanism that allows for variable locking degrees. This means it behaves more like an open differential during gentle cornering, reducing tire scrub and drivetrain binding, but locks up firmly when you apply throttle. This dual personality makes it a popular choice for drivers who want improved performance without sacrificing daily drivability. The unit is built with robust materials to handle the demands of performance driving.

Installing an LSD like this is a substantial upgrade for your RX-7 or RX-8. It directly impacts how the car accelerates out of corners and how stable it feels under power. Because this is a specialized drivetrain component, it's recommended to have it installed by a qualified mechanic who is familiar with differential work. They will ensure proper backlash settings and fluid levels are maintained for optimal performance and longevity. This OS Giken unit is a solid option for anyone looking to enhance their Mazda's handling characteristics.
