Product Details

The Bilstein B8 Performance Plus line is engineered for vehicles using aftermarket lowering springs, making it a strong choice for a Ford Focus suspension upgrade where ride height and handling balance matter. On the 2014-2018 Ford Focus, front left, this strut assembly is tuned to work with lowered spring setups while maintaining the control and precision expected from Bilstein shock absorbers. The monotube construction helps deliver stable damping performance, and each unit is tested to meet or exceed OE standards.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application. Use part number 29-256402 when verifying the correct front left strut for your Ford Focus build.

Common Issues This Part Can Address

• Excessive body movement after lowering the suspension
• Reduced front-end control during cornering
• Inconsistent damping response from worn OE struts
• Loss of ride quality after spring upgrades
• Front left strut replacement on a 2014-2018 Ford Focus

Installation Notes and Tips

Confirm the vehicle is a 2014-2018 Ford Focus and verify the front left position before installation. This strut is intended for use with aftermarket lowering springs, so spring height and suspension geometry should be checked during service. Inspect related suspension components, alignment settings, and mounting points before returning the vehicle to service.
