KYB Suspension Strut and Coil Spring Assembly P/N:SR4077K

Raise the front of your truck with this KYB strut assembly, the Truck-Plus Leveling Assembly (SR4077K), a complete strut and coil spring assembly that installs as a direct-fit front replacement for the 2004-2008 Ford F-150 and 2006-2008 Lincoln Mark LT — see the Buyer's Guide tab for engine-level fitment.

• Corner-specific engineering: KYB manufactures corner-specific part numbers instead of a one-size-fits-all design, helping restore the vehicle's designed performance.
• Application-engineered spring: a KYB spring matched to the strut to help maintain proper ride height longer and control weight without sacrificing ride quality.
• KYB Excel-G strut: a stronger steel outer shell with KYB's application-specific precision-designed damping valves.
• Safety-system aware: engineered to help vehicles with electronic safety systems (ESC, ABS, etc.).

On a 4WD 2004-2008 Ford F-150, it is designed to raise ride height approximately 2.5 inches while maintaining designed performance. Mounted at the front, a strut assembly handles vehicle weight, sets ride height, acts as the steering pivot and controls stability. It arrives pre-assembled with all required hardware for professional results and is assembled in the USA — and was named a 2021 Best New Product winner.
