L.S.D. refers to Limited-Slip Differential Gear, used in the center and final-drive, differential-gear section of most automobiles. While standard "open-differential" is commonly used on mundane production vehicles to allow the rotational difference of outside and inside wheels, in motorsports application requires that the driving wheels transfer power to the road surface regardless of condition, surfaces, driving style, and automobile design weaknesses.

The purpose of LSD is to limit the 'free-wheeling' of any wheels that are slipping, or airborne, and otherwise preventing the power from transferring to the ground. LSD system does this by providing a certain controlled amount of locking effect to each of the driving wheels, so that the power is transmitted to all driving wheels affected.

Common and generic discussions about LSD systems, floating around the modern Internet, stress that the LSD systems simply increase traction. Or, simply claim to provide grip for "better performance." However, we at Cusco believe and design our products based around principles that are much deeper than these simple generalizations. Our racing background and deep R&D experience goes back nearly half century, and as a company founded in 1977, our products have always stayed true to advanced motorsport benefits and on-going development.

We believe that the L.S.D systems should work to provide drivers with least amount of compromises, and fine-tuning in all aspects to cater a precise character that a driver might need for a very wide variety of motorsport stages. It should not simply lock the differential, but be available to lock when needed, and not lock when it isn't optimal to do so. Cusco LSD provides many elements that can be tuned and tailored, and have multiple system configuration to match the character of how it locks, when it locks, and releases, and adjustability of strength of the lock, and responsiveness of each of these factors.

Cusco also understands that the Limited Slip Differential systems can affect the overall handling of the car, therefore also the chassis and suspension requirements and optimization will also change accordingly. It is the cumulative overall design of every component of the car, which will determine the settings and needs of each of these items. This is why Cusco offers a full-line of chassis bracing, suspension systems, and dynamic alignment correction components to setup a car to the best potential, counting on each element to achieve the best balance, and closer to the goal of the driver and teams to win competitions, or provide more tactile road cars for the discerning owners.

At Cusco, we call this adherence to constantly strive for total balance, and relentless tuning to be ever closer to perfection, with a single Japanese word, "TAKUMI."

Suited for Drivers who:

  • Prefer lower maintenance on racing-grade Limited Slip Differential Units.
  • Prefer more immdiacy in actuation response right from the initial lock setting to maximum preset lock rate.
  • Drive lower-powered, compact cars in competitions
  • Does a lot of Standing-Start drag racing and short track, autocross with light-trigger starts.
Features:
  • Initial lock setting is more consistent and evenly spread over friction plates over traditinoal LSD systems
  • Inner-coil spring design allows for less initial lock settings on frictions plates than traditional LSD to achieve similar response.
  • Springs keep the friction plates in contact evenly and aids to prolong the life of the plates, while also preventing deformation of plate surface.
  • Choice of 2 Cam Ramps on the Pressure Plate for Tuning.
  • Ability to be adjusted for initial torque settings via positioning and number of coil springs.
  • Vector of forece applied by the pressure plate is the same as the intitial lock springs,making the LSD actuation consistent.
  • Chattering of plates are minimized in the RS Type design with consistent pressure across the radius of the friction plate surface.
Fitment:
  • Suzuki Swift Sport ZC31S
