Diff length is measured from Wheel mounting face to Wheel mounting face, from this measurement we then deduct 5mm per side for 35Spl Axles & 7.5mm per side for 31Spl Axles to allow for Rotor thickness. Please allow up to 10mm+/- on the finished diff length for variances in manufacturing.
Please ensure you have the correct measurement, no refunds will be given on incorrect diff length.
