These liners are produced from high quality spun GG30 cast iron with an outside diameter of 74.3mm, to allow worn-out bores to be reclaimed.

The material quality is that much higher and more consistent than the original blocks.

With an inside diameter of 69.55mm, these can be fitted and bored to a standard (70.6mm/2.78-inch) bore size, right up to +0.060-inch (72.14mm/2.840-inch). These should be fitted to a step in the bore for the best retention.

Sold as a set of four.
