Product information

Included in this listing is a set of brand new pistons, rings and gudgeon pins to fit a 3.9 Rover V8, supplied here with +20 thou pistons and rings. The pistons here give a 9.35:1 compression ratio, meaning that they also make a great upgrade for engines which previously ran an 8.13:1 compression ratio, assuming that your bores are machined to +20 thou. Gudgeon/wrist pins are also supplied for fitting the pistons to your rods, and all parts supplied are the same as we would use when building one of our own engines, so you can be sure of excellent quality.


Technical Specifications

RPi Advice
