Description

Restore front ride height and original handling on your 4WD Ford F-150 with the KYB Strut-Plus Suspension Strut and Coil Spring Assembly SR4171 — a complete corner unit that combines the strut, mount and spring in one pre-assembled front piece. It drops in as a direct-fit replacement for the front of the 2009-2013 Ford F-150 (4WD).

A strut assembly helps support vehicle weight, sets ride height, acts as the steering pivot and contributes to vehicle stability. As an OE supplier, KYB builds the Strut-Plus to help restore those handling and control capabilities.

Complete corner unit: strut, mount and spring engineered and pre-assembled for professional results.
KYB Excel-G strut: stronger steel outer shell with KYB's application-specific precision-designed damping valves.
High-carbon steel coil spring: application-engineered to match the strut, help maintain proper ride height longer and control weight without sacrificing ride quality.
Electronic-safety aware: engineered to help vehicles with electronic safety systems (ESC, ABS, etc.); assembled in the USA.

See the Buyer's Guide tab for full engine-level fitment.
