Type 4 Barrel And Piston Kit - 90mm - 1700cc

This replacement barrel and piston kit is designed specifically for Type 4 1700cc aircooled engines fitted to early VW Baywindow buses. Suitable for CA and CB engine codes, this kit uses flat top pistons and correct factory dimensions to restore original compression, performance, and reliability.

The pistons and barrels form the heart of the engine’s combustion system. Worn cylinders or pistons can lead to low compression, excessive oil consumption, poor starting, and reduced power. This complete matched kit provides all the critical components required to rebuild the top end of your 1700cc Type 4 engine, ensuring proper clearances and consistent performance across all four cylinders.

Manufactured as a good-quality reproduction, the cast barrels are precision-machined to accept the supplied flat top pistons, rings, and gudgeon pins. The flat top design is essential for maintaining the correct compression ratio on CA and CB engines and should not be substituted with domed or dished pistons.

This kit is ideal for full engine rebuilds, worn bore replacement, or performance restoration, and offers a straightforward installation when used with standard Type 4 cylinder heads and components. Strongly recommended to replace piston rings, wrist pins, and clips as a matched set to ensure long service life and smooth operation.
