Restore front ride height and control on your truck with the KYB Strut-Plus Suspension Strut and Coil Spring Assembly SR4202, a complete corner unit that drops in as a front, pre-assembled replacement for the 2005-2021 Nissan Frontier (see the Buyer's Guide tab for engine-level fitment). A front strut assembly helps carry vehicle weight, sets ride height, serves as the steering pivot, and contributes to vehicle stability — KYB pairs the strut, mount, and spring so you replace the whole corner in one step.
- OE-Restoring design: built around a KYB Excel-G strut with a stronger steel outer shell and application-specific, precision-designed damping valves.
- Application-engineered spring: high-carbon steel coil springs developed around the vehicle's attributes and corner weights to help keep ride height within OE specifications.
- Electronic-safety aware: engineered to help vehicles equipped with electronic safety systems such as ESC and ABS.
- Assembled in the USA and pre-assembled for professional installation. Winner of the 2018 Best Overall Import Aftermarket Product.
Signs a strut assembly may need replacing include excessive bounce, nose-dive under braking, uneven ride height, or clunking from the front suspension.
