The AMS Performance Q50 & Q60 Rear Limited Slip Differential allows for quicker acceleration and faster cornering, no matter the road conditions. The Infiniti Q50 and Q60 as they come from the factory utilize an “open” differential with no ability to lock or reduce slip between the left and right wheels. This unequal distribution of power causes massive wheel spin and loss of traction for one of the tires. To rectify this, our team has designed a helical type LSD constructed of HRC60 hardened 8620 forged steel, allowing for a mechanical reduction in slip between the two rear wheels. Put simply, the AMS Q50 & Q60 LSD allows the rear wheels to operate in unison, improving traction. The best part of the AMS Q LSD is its refined road manners, with no clunking, binding, or chatter that you would normally experience with other types of differentials.
