OS Giken Superlock LSD — a proven, patented mechanical limited-slip differential featuring the L.T.C.S. (Lock Timing Control System) for smooth, open-diff-like behaviour under light throttle and progressive 100% lock under acceleration. The S.T.S.G. (Spline Through Side Gear) design fits 1.5-2x more friction plates than a conventional LSD, delivering full lock with minimal heat generation and no measurable degradation after 150,000km+ of testing.
Fitment: Suits Nissan Skyline GT-R BNR32, BCNR33, BNR34 (rear diff). Not for V-spec models with active LSD. Early BNR32 (pre-Jan 1993) 30-spline flanges need upgraded flanges 38220-12U00/12U01.
