Quaife ATB Helical LSD differential for Vauxhall/Opel F40 is suitable for all models with the F40 gearbox. A direct replacement for the standard Vauxhall open differential, the Quaife ATB Helical LSD differential transforms your car's performance.
Unlike a conventional plate-style limited slip differential, the Quaife ATB Helical LSD differential relies on gears rather than clutch plates for its operation. That means it is much smoother in operation.
The 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 F40 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 F40 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 F40 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.
The Quaife ATB Helical LSD differential for F40 gearboxes is also now subject to a lifetime warranty (subject to terms and conditions).
We recommend changing to Millers CRX Fully Synthetic 75-90 gearbox oil when changing a differential and having a pair of driveshaft seals handy just in case.
