This differential is for Non-ACD Evo models. Evo 4 5 6 models are Non-ACD. USDM Evo 8 is Non-ACD only from 2003 to 2004 model years. USDM Evo 8 9 from 2005-2006 requires machine work to Quaife differential for proper fitment.
Note: Mitsubishi made 3 cone sizes for the non-ACD models, one is a direct fit, one requires to be machined at one end, and one requires to be machined at both ends. It is impossible to tell if the Quaife differential is a direct fit until the transfer case (front diff) is opened.
Quaife ATB Helical LSD differential is suitable for Mitsubishi Lancer 5, 6, 7, 8, 8MR, 9 (front, without crownwheel, 5-speed non-active centre) models. A direct replacement for the standard Mitsubishi open differential, the Quaife ATB Helical LSD differential transforms your car’s performance.
Unlike a conventional plate-style limited slip differential, the Mitsubishi Lancer Evo 5, 6, 7, 8, 8MR, 9 (front) Quaife ATB Helical LSD differential relies on gears rather than clutch plates for its operation. That means it is much smoother in operation.
The Mitsubishi Lancer Evo 5, 6, 7, 8, 8MR, 9 (front) 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 Mitsubishi Lancer Evo 5,6,7,8,8MR,9 (front) 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 Mitsubishi Lancer Evo 9 front 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 Mitsubishi Lancer Evo 5, 6, 7, 8, 8MR, 9 (front) 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.
With over 370 applications, the Quaife ATB Helical LSD differential is second to none. Accept no imitations!
Quaife ATB Helical LSD differentials are used by Ford, General Motors and Daimler-Chrysler as original equipment.
The Quaife ATB Helical LSD differential for Mitsubishi Lancer Evo 5,6,7,8,8MR,9 (front is also now subject to a lifetime warranty (subject to terms and conditions).
