Product Details
Triple S Lowering Springs for the 2012-2017 BMW 340i (6cyl) lower your BMW 340i's center of gravity for a cleaner stance, sharper turn-in, and reduced body roll while keeping daily-driver comfort. Engineered specifically for the 2012-2017 BMW 340i (6cyl), these progressive-rate springs deliver an approximate -21mm front and -19mm rear drop — a balanced stance that improves handling without the harshness of an aggressive cut. They are a direct replacement for the factory coils and bolt in without cutting, welding, or other modifications.
Unlike most aftermarket lowering springs, every Triple S application is engineered around the chassis it fits — in this case the BMW 340i (6cyl) — so the drop is matched to the factory damper's stroke. That means you keep your OE shocks and avoid the extra cost of replacing dampers just to prevent them from bottoming out. The result is a mild, street-friendly drop that preserves ride quality and extends the life of your factory suspension.
Triple S springs are cold-forged from SAE9254 silicon-chromium alloy by Yang Min Enterprise — an OEM coil-spring manufacturer with over 50 years of experience and ISO 9001, IATF 16949, and ISO 14001 certifications. Cold forging yields higher stress tolerance and tighter rate consistency than hot-forged springs, so each set delivers predictable, repeatable performance for the life of the part. A durable blue powder-coat finish resists chips and corrosion, and every set is backed by a 1-year manufacturer defect warranty.
Kit includes one pair of front springs and one pair of rear springs (4 total) engineered for the 2012-2017 BMW 340i (6cyl). Silencer rubbers are included where applicable.
