Model

If your vehicle has an engine swap, select the option that corresponds to the original factory engine.

Drive

Is your vehicle right hand drive or left hand drive?

Ratio

Choosing the correct diff ratio is essential. All Defenders are fitted with a 3.54:1 ratio as standard. No higher ratios are available, but lower ratios can be fitted. Recommended if running larger tyres. Use the ratio calculator to compare how different ratios affect vehicle speed and engine RPM.

Centre

Choosing the right differential centre is crucial and depends on how you use your Land Rover.

• Long Nose diffs come with a 2-pin centre as standard.

• Short Nose diffs feature a 4-pin centre.

If your Land Rover is used for more than everyday driving such as towing, off-roading, or overlanding upgrading the diff centre is highly recommended.

Options include:

• ATB (Automatic Torque Biasing) Limited Slip and 4-Pin Heavy Duty centres – both improve strength and durability.

• The ATB is our preferred choice, as it not only increases strength but also significantly reduces transmission slack while improving handling and traction.

• Air Locking Diffs are ideal for serious off-road applications.

Casing

Pegging your differential is strongly recommended for any high-powered Land Rover. If your vehicle has a tuned or upgraded engine—such as a tuned TD5, BMW M57, or V8 pegging becomes almost essential.

Pegging involves modifying the differential casing to fit a phosphor bronze pad behind the crownwheel, at the point where it meets the pinion. This pad prevents the crownwheel from flexing and failing under heavy load. The pad is securely held in place by two studs set into the diff casing.
