Quaife ATB Helical LSD differential for Dodge Charger SRT8 is suitable for Dodge Charger SRT8 models. A direct replacement for the standard Dodge open differential, the Quaife ATB Helical LSD differential transforms your car’s performance. Unlike a conventional plate-style limited slip differential, the Dodge Charger SRT8 Quaife ATB Helical LSD differential relies on gears rather than clutch plates for its operation. That means it is much smoother in operation. The Dodge Charger SRT8 Quaife ATB Helical LSD differential never locks harshly with a set pre-load of wheel slip across the driven axle, like a conventional LSD. Rather, the Dodge Charger SRT8 Quaife ATB Helical LSD differential automatically biases the torque away from the spinning wheel across the axle, to a constantly varying degree, and never locks. The Dodge Charger SRT8 Quaife ATB Helical LSD differential has many benefits over a standard open differential, including maximising traction and minimizing wheelspin, eliminating torque steer and snatching in front wheel drive cars compared to conventional LSD units, and a maintenance-free design which retains the standard oil lubrication. The Dodge Charger SRT8 Quaife ATB Helical LSD differential is proven in circuit and drag racing, rallying and road use, and is produced from Corus steel billets, and is CAD designed and CNC machined, then inspected to ISO 9001 standards. Quaife ATB Helical LSD differentials are used by Ford, General Motors and Daimler-Chrysler as original equipment. The Quaife ATB Helical LSD differential for Dodge Charger SRT8 is also now subject to a lifetime warranty (subject to terms and conditions). Thanks, Lisa.
