The KYB Truck-Plus Performance Assembly SRG4171 is a front suspension strut and coil spring assembly built for 2009-2013 Ford F-150 applications with specific package and suspension configurations. It combines KYB Gas-a-Just monotube performance with exact-fit assembly engineering for a direct replacement on the front end.

• KYB Gas-a-Just complete strut assembly from an OEM-quality shocks and struts brand
• Up to 25% more damping performance than standard shock absorbers on Ford F-150 applications
• Heavy-duty monotube shock absorber design for added handling and control
• Built for trucks that work, tow, haul, or see off-road use
• Pre-assembled for professional results and exact fitment
• Engineered to help vehicles with electronic safety systems such as ESC and ABS
• Assembled in the USA

Truck-Plus Performance Line Details

KYB Truck-Plus Performance Assembly products are designed as application-specific replacements rather than one-size-fits-all parts. For the Ford F-150, SRG4171 is built to address the demands placed on the front strut assembly, including vehicle weight support, ride height, steering pivot function, stability control, and interaction with electronic crash-avoidance systems. This part number is also a cross-reference for Monroe Shocks & Struts 153031 for the same application.

Fitment

What It Helps Address

• Suspension wear on 2009-2013 Ford F-150 front applications

Installation Notes

SRG4171 is a pre-assembled front strut and coil spring assembly for the specified Ford F-150 configurations. Verify package, suspension, bed length, and front position before installation. Because the strut assembly affects steering geometry and electronic safety system behavior, professional installation and a post-install alignment are recommended.

Quality Assurance

KYB is known for OEM-quality shock and strut engineering, and the Truck-Plus line is built with application-specific design rather than universal fitment. SRG4171 is assembled in the USA and engineered for front suspension performance on the listed Ford F-150 models.
