Piston set w/rings B18 0.040"

Volvo B18 Piston Set – +0.040" (85.16 mm)

Oversize piston set for the Volvo B18 engine, intended for blocks that have been bored and honed to +0.040" (85.16 mm). Ideal for rebuilds where worn cylinders need to be restored to correct tolerances for stable operation and long-term durability.

The set fits Volvo B18 engines used in classic models such as the Amazon, PV/Duett, 140 Series, and early P1800. A proven choice for original restorations, street-driven cars, mild performance builds, track days, and historic motorsport where standard-type components are often preferred.

Designed for the complete B18 inline-four engine and used together with piston rings in the matching oversize to ensure proper sealing and long service life.
