Piston Ring Set for the engine bottom end — the compression and oil-control rings that seal the pistons in their bores.

Fitted into the piston ring grooves, the rings seal combustion pressure above the piston, regulate the oil film on the cylinder walls and carry heat from the piston into the bore. This set covers a full engine. For the 2.5L 4-cylinder naturally aspirated diesel engine.

Frequently asked questions

What is the STC77240 piston ring set and what does it do?
The STC77240 is a piston ring set for the 2.5-litre four-cylinder naturally aspirated diesel. Fitted into the piston ring grooves, the rings seal combustion pressure above the piston, control the oil film on the cylinder walls and carry heat from the piston into the bore.
Does the STC77240 set cover the whole engine?
Yes, this set covers all four cylinders for one complete 2.5-litre naturally aspirated diesel engine. You don't need per-cylinder packs. It supplies the compression and oil-control rings for a full engine rebuild or re-ring.
Which Land Rover does the STC77240 piston ring set fit?
The STC77240 piston ring set fits the Land Rover Defender (1987-2006) with the 2.5-litre four-cylinder naturally aspirated diesel engine. It's specific to the NA diesel, so confirm your engine isn't the turbodiesel or Td5 before ordering, as those use different rings.
What are the signs the piston rings need replacing?
Worn piston rings usually show as blue exhaust smoke, high oil consumption and loss of compression or power. On the 2.5 NA diesel, rings are renewed during a bottom-end rebuild once bore wear or glazing lets combustion gases past. New rings restore the seal between piston and bore.
