The Bilstein B6 Performance 36mm rear shock is a gas-pressure monotube damper built on Bilstein's upside-down monotube design. The manufacturer describes the B6 Performance line as an upgrade over OE dampers, with each unit individually tuned during road testing. For a 924 owner replacing a tired stock unit, that means a firmer, more controlled rear end on spirited driving, and the long-life gas-pressure construction is a durability argument over cheaper twin-tube replacements.
Fitment is the first thing to verify. Retailer listings place this rear unit on 1977 to 1982 Porsche 924 Base models, with 1979 to 1982 924 Turbo and 1983 to 1984 944 Base also appearing, but the year cutoffs and submodel coverage differ between sources, so confirm with the manufacturer against your VIN before ordering. Lower eye diameter also varies across listings, so check your existing bushing or mount before you buy. Searchers looking for a Bilstein 24-001618 rear shock for a 924 or 944, a B6 performance rear damper, or a 36mm gas monotube for a Porsche 924 will find this is the right part family.
The manufacturer describes the B6 Performance rear unit as a gas-pressure monotube design with upside-down construction, which differs from the twin-tube layout found on many standard replacements.
Published fitment varies between sources, with year ranges and submodel coverage differing for the 924 Base, 924 Turbo, and 944 Base. Confirm the application with the manufacturer using your VIN and compare the lower eye size with your existing hardware before ordering.
