Arnott Rear Air Strut Assembly - Right - BMw E65 E66

Keep your E65/E66 7 Series riding like a proper flagship—smooth, level, and composed—with no more sag, bounce, or endless compressor cycles. The Arnott Rear Air Spring isn’t just a replacement—it’s the solution for cracked, leaking, or tired OE bags that rob your BMW of ride quality, rear-end balance, and that signature self-leveling precision. As the originals age, the rubber bladders lose pressure, leaving your 7 Series sitting low and forcing the compressor to work overtime. Arnott brings your suspension back to factory spec with rugged multi-ply air bladders, OE-style crimp rings, and reinforced seals built to outlast stock. Designed for direct fit, installation is straightforward—bolt in, inflate, and enjoy. The result is quiet operation, a level stance, and confident handling whether you’re commuting, cruising, or loaded for the long haul. Why choose Arnott Rear Air Springs for E65/E66? Restore factory ride – Swap out sagging OE bags for fresh, durable replacements. OEM-level construction – Premium bladders and hardware built for longevity. Consistent performance – Engineered to resist leaks, dry rot, and pressure loss. Direct-fit design – Bolt-on installation, no cutting or adapters required. If your E65/E66 rear suspension is sagging and the compressor won’t stop, Arnott rear air springs restore the poise, comfort, and legendary BMW ride your 7 Series was built for.
