E46 xi Bilstein B8 Rear Shock Absorber - Part Number 22-153927

For E46 xi owners running lowering springs and chasing fast-road composure or track-day repeatability - not just a taller spring perch or softer rebound.

• Monotube gas pressure design, shortened body & E46 xi-specific valving - no spacers, no guesswork
• Works with E46 xi rear trailing arms and standard top mounts; fits with M-sport, non-M and xDrive variants
• Stage 1 or stage 2 fast-road setups: pairs cleanly with Eibach Pro-Kit, H&R Sport, or Swift Spec-R
• Also used on decat + remap builds where chassis control matters more than comfort - think N52 or S54 swaps
• Sold individually; for full upgrade, add two (part number same)
