OS Giken Super Lock LSD for MK4 Supra/SC300. This 1.5 way LSD is great for cars that will be driven both on the street and the track. It fits the 200mm diff in the MK4 Supra NA or Turbo Automatic, and also the Lexus SC300/400. It does NOT fit the 6 speed Supra with a 220mm B-Series differential.
The TY031-HA part number is with the standard 1.5 way setting and this is used on street cars and multi-purpose use cars.
The 2 way setup (TY031-HB) is typically used and recommended only for race cars. The 2-way is a special order item.
The OS Super Lock LSD is the culmination of over four years of extensive research and development that led to a revolutionary LSD design with the capacity to house an unprecedented number of friction plates (up to 28 plates in total). Combined with our patented lock timing system, the Super Lock LSD is able to achieve complete lock in a progressive, smooth, and quiet manner, making it suitable for both street and racing performance.
Fits all 200mm differentials, MKIV NA, MKIV TT Automatic: A05A, A01A, A02D, A02A, A02B
