Frequently asked questions

What does the STC958R piston ring set do?
The STC958R piston ring set seals one piston in the 2.5L 300 TDi diesel engine. It carries the compression rings and oil control ring for a single piston, sealing combustion pressure above the piston and controlling oil on the bore. It's supplied in standard size for bores at their nominal diameter.
How many sets are needed for a full 300 TDi rebuild?
Four sets are needed to ring a complete 300 TDi engine, since each set covers one piston and the engine has four cylinders. Order the STC958R in multiples of four for a full rebuild, or singly if you're only replacing rings on one piston.
Which Land Rovers use the STC958R piston rings?
The STC958R fits the 2.5L 300 TDi engine in the Defender (1987-2006), Discovery 1 (1989-1998, chassis FA393361 to WA799999) and Range Rover Classic (1992-1994, from chassis JA610294). Confirm your engine is the 300 TDi, as the earlier 200 TDi typically uses different rings.
What does 'standard size' mean for these rings?
Standard size means the STC958R rings suit bores and pistons at their original nominal diameter. If the block has been rebored oversize, standard rings won't seal correctly and you'll need matching oversize rings instead. Check the bore size before ordering.
