This Bilstein B6 is a rear replacement shock absorber for the 1977 Chevrolet Corvette base model, built as a 46mm monotube unit. It replaces the rear damper on a classic Corvette that is due for a fresh suspension. Enthusiasts searching for a 1977 Corvette rear shock, a Bilstein 46mm monotube shock, or a direct-fit C3 Corvette rear damper will find this part matches that description. Published fitment ranges for this part number vary across references, so confirm the exact model year and drivetrain with the manufacturer before ordering.
Compared with a worn original damper, a monotube design gives a more consistent damping feel as the shock heats up under repeated use, which is the main reason owners upgrade. The rear shock is a straightforward bolt-on job for a home mechanic with basic hand tools, since it mounts at the rear axle and body without requiring suspension disassembly. Check the mounting hardware and bushings for wear while the old unit is off, and confirm the installed length against your current springs.
