OS Giken 1.5 way LSD
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.
Details
Each component of every OS Giken Super Lock LSD uses only the highest grade materials and manufacturing processes. They are constructed and finished to extremely tight tolerances to eliminate “break-in” period prior to racing conditions. Expect longer life out of LSD performance compared to its competition. Rebuilds are rarely needed and is recommended to have fluids changed periodically to prolong the life of the unit.
More Info
The OS-250R gear fluid is a specially formulated synthetic gear oil that contains the proper amount of gear oil and limited slip additive for LSD protection and reliable locking performance for our RWD applications With that being said, we have had success using a select few non-OS fluids in regards to protection.
