Product Details

The KYB Truck-Plus Leveling Assembly line is focused on truck front-end leveling and suspension restoration, with corner-specific part numbers rather than a one-size-fits-all design. For the Ford F-150, SRG4171KL combines a leveling strut assembly with a KYB Gas-a-Just monotube shock to improve control, steering response, and stability while maintaining the intended side-specific geometry. If you are searching for a 2009-2013 Ford F-150 front left leveling kit assembly or a KYB SRG4171KL replacement strut assembly, this part is built for that application.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

Common Issues This Part Can Address

• Front-end rake that leaves the truck nose-down
• Worn strut performance causing reduced ride control
• Excessive bounce or body movement over uneven roads
• Loss of steering precision from aging front suspension components
• Uneven front ride height on the driver side
