1.5 Way
A 1.5-way limited-slip differential is the most common LSD upgrade option in performance and race cars. It is referred to as a 1.5-way because it functions under acceleration and to a lesser extent under deceleration. It provides differential locking characteristics under acceleration, maximizing power distribution to the wheels that need it most. Under deceleration, the 1.5-way LSD engages to assist in braking stability and smoother turn-in.
SuperQ (WPC treatment)
Every Kaaz limited-slip differential is offered in a SuperQ variant. SuperQ units feature reduced chattering and smoother engagement for an enhanced driving experience. With the help of WPC metal treatment, SuperQ limited-slip differentials also come with better heat dissipation and longer wear life with no break-in process required. Just like all of Kaaz’s limited-slip differentials, SuperQ units allow for locking rate adjustments.
