Cylinder base Spacer (Distance Plate) from DRT made of aluminum - for height compensation of Cylinders and for adjusting the timing/squeeze edge.

Cylinder base spacers from DRT are used when a Cylinder needs to be raised - e.g. for modified stroke lengths (long stroke) or to specifically change the timing. Thicker base/head spacers can provide the necessary compensation for a longer stroke; compensation via the cylinder base influences the timing of the exhaust and transfer ports, among other things. The versions mentioned here are just as suitable as spare parts (for repair/revision) as they are for rebuilding tuned engines:
