Frequently asked questions

What is the RTC437420 piston ring set for?
It's an OEM-spec full piston ring set for one piston on the 2.25 litre 4-cylinder petrol engine, machined 0.020 inch oversize for a rebored block. Fits Defender (1983-2006) and Series IIA/III models with the 2.25 petrol engine.
How many sets do I need for a full rebuild?
One set per piston. A 4-cylinder 2.25 petrol engine needs 4 sets total, since it's sold per piston rather than as a complete engine kit.
What's the difference between RTC437420 and RTC419020?
Both are 0.020 inch oversize ring sets for the same 2.25 petrol engine. RTC437420 is OEM spec, while RTC419020 is the genuine Mahle version. They're interchangeable for the same rebore.
Why does this engine need oversize rings?
Oversize rings are typically fitted once the cylinder bores have been machined oversize to remove wear or scoring during a rebuild. Standard-size rings won't seal correctly against a rebored cylinder.
