Heavy Duty Rover 3.5 Ring & Pinion - Rear

  • FAQs

    I want to fit the Heavy Duty 3.5 ratio ring and pinion in the rear axle but leave the 3.54 in the front (or visa versa), will this be OK ?

    There will be a ratio difference but it is quite small, with the centre diff locked on a low traction surface this will be OK as occasionally one wheel may slip to stop the driveline ‘winding up’. When on road with the centre diff unlocked, the centre diff will turn slowly to allow for the ratio difference, this slow turning will not wear the diff excessively. The only instance where this ratio difference could cause a problem would be if you were on the road or on a high traction surface with the centre diff locked which of course you should not be.
