What It Helps Address

• Front-end sag on a 1992 BMW 320i or 325i
• Uneven ride height at the front suspension
• Loss of spring tension from age or fatigue
• Noise or harshness caused by worn coil springs
• Suspension refresh during front-end service

Installation Notes

Compatible With 1992 BMW 320i, front, through 06.1992, and 1992 BMW 325i, front, through 06.1992. Verify the vehicle build date before ordering, since fitment is limited to cars produced up to month/year 06.1992. Seat included is not provided, so reuse or source the correct spring seat as needed. Because coil springs are under high load, professional installation and proper spring compression equipment are recommended.
