Piston Assembly for the 2.7L TDV6 diesel engine, supplied in the +20 oversize.

The piston reciprocates within the cylinder bore of the engine block, transferring combustion pressure through the connecting rod to the crankshaft. The +20 oversize is fitted after the cylinder block has been rebored, restoring the correct piston-to-bore clearance during an engine rebuild or reconditioning.

Select the oversize to match the finished bore of the reconditioned block.

Frequently asked questions

What is the BR 4102 piston assembly used for?
The BR 4102 is a +20 oversize piston assembly for the 2.7L TDV6 diesel engine. It reciprocates in the cylinder bore, transferring combustion pressure through the connecting rod to the crankshaft. The +20 oversize is fitted after the block has been rebored during an engine rebuild.
How many pistons are needed to rebuild a 2.7 TDV6 engine?
A 2.7 TDV6 has six cylinders, so a full rebuild typically needs six matched pistons. They're usually fitted as a complete set so every bore shares the same oversize and piston-to-bore clearance. Order the quantity to match the number of bores being reconditioned.
What does the +20 oversize mean and how do I choose it?
The +20 oversize means the piston is machined larger than standard to suit a cylinder block that's been rebored. Select the oversize to match the finished bore of your reconditioned block, otherwise the piston-to-bore clearance will be wrong. Confirm the machined bore size before ordering.
Which Land Rover models use the BR 4102 piston?
The BR 4102 fits the 2.7L TDV6 diesel in the Discovery 3 (2005-2009), Range Rover Sport L320 (2005-2013) and Range Rover L322 (2006-2012). All three share the same TDV6 engine. Use your VIN to confirm the engine variant before ordering.
