Clutch-type LSD with adjustable initial torque (6.5-8.5-14.0kgf·m *1)
The GT L.S.D. Pro is the ideal solution for drivers who are spending too much time working on their LSD. Otherwise identical to the standard GT L.S.D., the GT L.S.D. Pro adds one unique feature: you will be able to re-set your initial torque with just a turn of your socket wrench and without disassembling your LSD. With a low, middle and high setting (6.5 - 8.5 - 14.0kgf·m), easy adjustments can be made for changing driving styles, tires, suspension, tuning or track conditions. As initial torque decreases with aging parts, changing the initial torque setting -LOW two times, MIDDLE once- will save you money on overhaul costs.
*1 The design standard for initial torque output values is 6.5 - 8.5 - 14.0kgf·m. After the LSD is broken in and the plates are working well together, these figures will stabilize at LOW: 5.0 to 5.5; MIDDLE: 7.0 to 7.5; HIGH: 12.5 to 13.0kgf·m. The GT L.S.D. Pro ships pre-set to the "middle" setting.

Parts & Build
- Shallow groove = High initial torque (plate spring pressure is high)
- Deep groove = Low initial torque (plate spring pressure is low)
The plate springs (#3 top right) press against the adjustment plate (#2 top right) inside the pinion mate shaft and function together as a set. Three different grooves of varying depth are cut into the "adjustment" plate (2). Initial torque is changed by depressing the spring and moving the plate to the groove corresponding to the desired setting.
<Details> The plate (#2 top right) is held (fitting into "Right side") by the cap (#1 top right) and reset.
Re-setting initial torque
*The central hex bolt (#1 in photo above) is turned using a socket wrench.
With the car raised on a jack or rack, the right side axle is unbolted and the side flange removed. A ratchet and socket can then be inserted to turn the pinion mate shaft left for low, center for middle, right for high.
