Bilstein B6 24-007306 rear shock for BMW E12 (518, 520, 525, 528, 530i, 1972-1981). Monotube gas-pressure damping, 46mm piston, digressive valving - built for drivers who still autocross their E12 or want a tauter, more responsive fast road setup.

• Stage 1 suspension upgrade - pairs cleanly with stock springs and factory geometry; no spacers, no camber kits needed
• E12-specific fit - direct bolt-on to original top mounts and lower brackets; no modification required
• Track day capable - consistent fade-free rebound control under repeated load, unlike twin-tube units
• Daily driver friendly - firmer than OE but not brittle; handles UK B-roads without punishing the spine
