MFactory Final Drive for Honda Civic and CR-X EF, cable clutch gearbox
Supplier stock
The MFactory final drive in 4.7, 4.9 ratios replaces the ring gear and pinion on the Honda Civic and CR-X EF. A shorter ratio multiplies torque more at the wheels: the car pulls harder in every gear, and top speed drops.
