Product Description

The KONI 8250 1021 STR.T Rear Shock is a direct-fit performance shock absorber engineered for the rear suspension of the 1997-2003 BMW 5-Series E39 (including 525i, 528i, 530i, 540i, and M5 sedan applications). As part of KONI's STR.T ("Street") series, this shock delivers a tuned damping rate that improves handling dynamics and ride quality compared with basic OE replacements. Its non-adjustable design provides a balance of performance and comfort suitable for both daily driving and spirited street use.

Featuring a gas-charged twin-tube construction and a corrosion-resistant orange finish, this shock absorber offers long-lasting durability and consistent damping performance. It pairs effectively with either stock springs or compatible lowering spring setups, making it a versatile choice for enthusiasts looking to upgrade their rear suspension without adjustable components. Sold individually, this shock is ideal for replacing worn rear shocks to restore improved control and ride feel.
