OS Giken Super Lock Limited Slip Differential | 1989-1998 Nissan 240SX (NS046-HA) OS GIKEN

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.
