Show original supplier description
The Tomei Technical Trax Advance LSD Kit (TC101A-HYKA2) is engineered to significantly enhance your Hyundai Genesis's driving dynamics. It features optimized cam angles, spring discs, and larger surface area clutch discs, coupled with a higher initial torque setting. These advancements translate into improved corner entry, more precise driving, better corner exit traction, and quicker response through successive corners, offering superior performance. The friction quality has been refined with a new surface finish, ensuring smoother operations and more stable behavioral changes. It notably eliminates loud LSD crackling sounds, making it more comfortable for daily street-driven cars. The LSD case itself is built to withstand extreme driving and high initial torque without warping, ensuring consistent performance. Each T-TRAX ADVANCE kit includes everything required for installation, such as Tomei's special differential oil, carrier cover gaskets, bearings, and oil seals, which are essential when upgrading the differential for many vehicle applications. The kit is compatible with Hyundai G4KF and Hyundai G6DA engines and has an initial torque range of 11.0-13.0kg.
