Frequently asked questions

What is the RTC4778020 piston ring set for?
The RTC4778020 supplies the compression and oil-control rings for one piston on the 2.5L 4-cylinder naturally aspirated diesel. It's machined 0.020 inch oversize to suit a cylinder that has been rebored, sealing the piston to the bore and controlling oil.
How many sets do I need for a full engine?
One set covers a single piston, so a 4-cylinder 2.5L diesel typically needs four sets for a complete rebuild. Order by the number of pistons in your engine, as this listing is priced per piston rather than per engine.
What does 0.020 inch oversize mean and when do I need it?
The 0.020 inch oversize (020) rings suit a cylinder bore machined out by 0.020 inch. Order this size only if your block has been rebored to 020. A standard, unbored cylinder needs standard-size rings, so match the rings to your actual bore size.
Which engine and vehicle does this fit?
This ring set fits the 2.5L 4-cylinder naturally aspirated diesel as used in the Land Rover Defender 1987 to 2006. It's the 0.020 inch oversize size, so it suits a rebored engine of that type.
