The J's Racing Limited Slip Differential was born with the objective of winning races. The J's LSD excels with it's great locking performance, quietness, and the durability. It's quality has been proven by performing excellently in all driving scenes. From the street to the super endurance series, J's Differentials will not leave you disappointed. J's LSDs promise smooth locking and excellent stability and are recommended for all types of drivers.
J's recognized the advantage of using a cone spring in an LSD, which has become the J’s Racing’s consistent LSD concept. From the first production, J's LSDs have been a clutch type which is externally pressured by coned spring.
In general, the power of a spring is proportionate to its force of either pulling or pushing. However, a cone spring features unique characteristics. The power remains constant to a certain point against the external pull or push, then it either increases or decreases in a different rate depending on the design of the cone spring. With these flexible characteristics, J's successfully designed the cone spring for the best LSD possible. It is a widely misunderstood concept that the locking performance of the LSD is equal to its initial torque. J’s Racing design concept is that LSD can generate ideal locking without relying on the strength of the initial torque.
By providing linear response to your throttle movement, adding a J's Racing LSD will provide a very stable driving feel. An LSD with large discs tends to cause erratic behavior on tight corners, creates loud chattering noise, and loses stability on fine throttle movement at high speed cornering. You do not have to worry about those negative points on a J's Racing LSD, though, as a J’s Racing LSD will give you a superb stability with smoothness.
