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 syste;, 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.
