Fiat Fullback Differential Replacement Parts

The Fiat Fullback was sold in the UK from 2016 to 2020, based on the Mitsubishi L200 fifth generation (Series 5), and received a mild facelift around 2019. The differential is a mechanically shared unit with the L200 of the same generation, so the facelift year is the key boundary to be aware of when sourcing a used part. Whether a pre-facelift differential crosses that 2019 boundary to fit a post-facelift Fullback is something you should confirm with the breaker against your registration, as ancillary and mounting changes can occur mid-production.

2017 and 2019 both fall within the Fiat Fullback's single UK generation (2016–2020), but 2019 sits at the facelift boundary, which is the point where subtle mechanical changes can sometimes be introduced. The engine code is the most important detail here — check your V5 or run a VIN check and supply that code to the breaker, as two trucks with the same year can differ if the engine code changed around that time. Confirm compatibility directly with the breaker against your registration before purchasing.

Trim level does not affect differential fitment on the Fiat Fullback — the SX and LX are mechanical siblings sharing the same drivetrain components. What matters is the engine code, fuel type, and whether the vehicle has a manual or automatic gearbox, not the badge or trim specification. You may find cosmetic differences between trim-level donor vehicles at the breaker, but the differential itself is determined by the mechanical specification, so focus your enquiry on those drivetrain details.

The engine code matters above everything else — it is the single most reliable way to ensure you source the correct differential for your Fullback. The year gives a useful starting point but two Fullbacks built in the same year could have differing specifications if, for example, output variants were offered. Pull the engine code from your V5 logbook or a VIN check and give it to the breaker alongside the gearbox type (manual or automatic) for the most accurate match.

The Fiat Fullback shares its platform and drivetrain with the Mitsubishi L200 fifth generation (2015–2019), so a differential from the equivalent L200 is widely regarded as mechanically interchangeable. Engine code, fuel type, and gearbox type must still align between the donor L200 and your Fullback — do not rely solely on the model name. Confirm the specific part number and your registration details with the breaker before buying, as ancillary fittings can vary between the two marques.

Yes, the differential specification can differ between manual and automatic gearbox variants even when the engine code is identical, because the torque management and transfer case setup may vary. Always tell the breaker both your engine code (from the V5 or VIN check) and your gearbox type to avoid ordering an incompatible unit. Never assume a differential from an automatic-equipped donor will suit a manual vehicle or vice versa without the breaker confirming compatibility against your registration.
