Quaife units QDF22R have rivetted crownwheels, so the customer will need either VW or ARP replacement bolt kits.
We offer ARP replacement bolt kits. Just select them up top and it will be added to your shopping cart!
Quaife builds the best torque biasing differentials in the world. These units work beautifully in rear wheel drive cars, but are an absolute must for front wheel drive applications: they allow for power to effectively, and smoothly reach the wheels without causing any additional binding or resistance under part throttle or lift throttle situations.
We used the Quaife Automatic Torque Biasing Differential in our VW GTI Group A Rally car for three seasons and won the championship in the final year.
Application: Volkswagon 020 transmission with 109 mm Crownwheel
