Front Suspension Strut Assembly for Toyota Tundra

The FCS DT345978 is a front suspension strut assembly for Toyota Tundra applications from 2007-2021. It is built around a monotube performance upgrade layout to improve shock absorption response at the front of the vehicle. The FCS DT345978 is a direct-fit option for drivers looking for a front strut assembly with performance-focused damping characteristics.

Key Features

• Front suspension strut assembly for Toyota Tundra
• Monotube performance upgrade construction
• Compressed length: 17.24 in.
• Extended length: 23.62 in.
• Stroke length: 6.38 in.
• Part number: DT345978

Product Details

FCS DT345978 is engineered for the front suspension on Toyota Tundra models and uses a monotube design to support more consistent shock absorption performance. With a compressed length of 17.24 inches, an extended length of 23.62 inches, and 6.38 inches of stroke, this strut assembly is specified for the front end geometry used across the listed Tundra applications. The FCS line focuses on suspension replacement parts, and this assembly follows that approach with fitment coverage for 2007-2021 Toyota Tundra front applications. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

What It Helps Address

• Front-end bounce or excessive oscillation on Toyota Tundra trucks
• Reduced damping response over uneven pavement
• Worn front strut assembly performance on high-mileage vehicles
• Loss of controlled ride quality during braking and cornering
• Front suspension replacement needs on 2007-2021 Toyota Tundra models

Installation Notes and Fitment

Fits 2021 Toyota Tundra, front. Fits 2007-2020 Toyota Tundra, front. Confirm the vehicle year and front suspension configuration before installation. Match the compressed length, extended length, and stroke length to the original strut assembly specifications for proper fitment on the Toyota Tundra. Part number DT345978 should be verified against the existing suspension setup before service.

Quality Assurance

FCS suspension components are cataloged for direct replacement use in listed vehicle applications. The FCS DT345978 front strut assembly is identified for Toyota Tundra fitment from 2007-2021 and is specified with published dimensional data for application matching.
