About These Td6 Diesel Cylinder Heads
A remanufactured pair of left- and right-side cylinder heads for the Land Rover 3.0L Td6 turbocharged V6 diesel (306DT / AJD-V6), found in 2016–2021 Range Rover and Range Rover Sport and 2017–2020 Discovery diesel models. Both heads are fully assembled with valves, springs, camshafts, lifters, and rockers — ready to bolt on.
Left side: part number LR083672 (replaces C2D50972), casting ident 9X2Q6C032BC. Right side: part number LR014249 (replaces C2D3613), casting ident 9X2Q6C032AB. Aluminum DOHC construction with 16.1:1 compression. Fits the 3.0L Td6 diesel only — not compatible with gasoline V6/V8 engines or the earlier 2.7L TDV6.
The Td6 is prone to cylinder head damage after overheating events, often triggered by coolant crossover pipe failures or EGR-related issues. New OEM castings run well over $2,000 bare, before cams and valvetrain — these fully assembled heads get your engine back together for a fraction of dealer cost. Backed by a 1-year warranty. U.S. customers pay no core charge, but the old cores must be returned within 30 days or the warranty is void, A prepaid core return label is included with each box. International customers only need to pay a $200 core charge (non-refundable).
Build time: remanufactured heads typically ship in 10–15 business days. Call for current turnaround.
