The overall performance of an LSD is naturally tied to the locking of left and right shafts, but do you really know to what extent the actual locking performance (generated torque) is transmitted to the shafts? In the case of poorly manufactured LSDs, the generated torque delivered to the left and right shafts can be quite different. This imbalance can make controlling the vehicle difficult during acceleration and deceleration (in the case of a 2-way), a situation that forces the driver to execute extra steering maneuvers. It will also make suspension and brake adjustments difficult, at which point installing the LSD makes no sense at all. The extreme precision of the GT L.S.D. series leverages large capacity with uniform torque to both the left and right shafts. GT L.S.D.’s stable, high traction performance permits fine tuning of both brakes and transmission settings.

The greatest disadvantage in increasing plate size or number is a resulting reduction in the size of the plate teethe or in the groove area of the side gear and case. This adds up to poor slip stability as well as a reduction of plate strength because of thinner plates. The GT L.S.D. series features plates with 16 outer and 8 inner precision tooled teethe manufactured to exacting standards in a dedicated, high-tech production facility for the highest slip performance attainable. Rather than focus on securing some meaningless oil line, we concentrated on stabilizing slip performance. The plates assembled in the LSD function in the same way as a rag clutch, shifting from slip to lock. When manufacturing standards are lower and the plates are badly manufactured, they do not lock correctly but only partially. The badly made LSD is thrown into an unending slip-lock-slip-lock cycle that causes gear oil temperatures to rise while reducing product lifespan due to plate judder vibrations. In an LSD, torque is generated when the pressure ring opens and the plate moves from slip to lock to produce the“ moment of force”. In the schematic below, the gray area representing the operation of another manufacturer’s LSD is wide and amorphous, whereas the blue GT L.S.D. area is thin and concentrated. A wide line is evidence that though the plates are slipping, the LSD is just barely engaging the locked state. Unnecessary slippage is something that should never happen in an LSD. It is not only inefficient but has a very negative effect on driver handling. This is reflected in driver comments such as“: Angle handling is very unstable. Something’s weird”“, Starting a drift was no problem, but I couldn’t hold it” or“ Oversteering and understeering are way out of whack”. On the other hand, the concentration of the GT L.S.D. blue area shows that the LSD is moving from slip to lock very precisely and without any unnecessary slippage both during acceleration and deceleration. Installing a GT L.S.D. is the shortcut to improved driving technique as well as vehicle tuning.
