What is the main benefit of installing a Limited Slip Differential (LSD)?

An LSD helps distribute torque more evenly between the drive wheels. This means that when one wheel starts to lose traction, the LSD can still send power to the other wheel, improving acceleration and stability, especially during cornering or in slippery conditions.

Is this LSD adjustable?

Yes, the OS Giken Super Lock LSD features an adjustable cam system. This allows for tuning the locking effect to better suit your driving style and the specific demands of the road or track.

What is required for installation of this differential?

Installing a differential is a complex job that typically requires transmission removal and disassembly. It's recommended to have this component installed by a professional mechanic experienced with Porsche manual transmissions and differential systems to ensure proper fitment and performance.

Product Details

This is the OS Giken Super Lock Limited Slip Differential (LSD) for your 2005-2012 Porsche Boxster S or Cayman, specifically for manual transmission models. If you're looking to put down power more effectively, especially when exiting corners or in low-traction situations, an LSD is a critical upgrade. It helps manage the torque distribution between your rear wheels, preventing one wheel from spinning freely while the other has grip. This means more consistent acceleration and improved handling dynamics.

OS Giken is well-known for their high-performance drivetrain components, and the Super Lock LSD is a popular choice for enthusiasts who demand more from their car's performance. This unit is designed to provide a very strong locking effect, which can be adjusted to suit your driving style and track conditions. The Super Lock design uses a unique cam system that allows for a progressive lock-up, meaning it engages more smoothly under acceleration but provides a near-solid lock when needed. This makes it effective for both spirited street driving and track use. The unit is built with durable materials to handle the stresses of performance driving.

Installation of a differential like this is a significant job, often requiring specialized tools and knowledge. It's typically done when rebuilding or servicing the transmission and rear axle assembly. Because this is a high-performance component, it's recommended to have it installed by a qualified mechanic experienced with Porsche manual transmissions and differential work. This will ensure proper setup and optimal performance for your Boxster or Cayman.
