Raise the front of your truck and restore designed ride height with the KYB Truck-Plus Leveling Assembly SR4201K, a complete front corner unit for the 2005-2021 Nissan Frontier. It arrives as a pre-assembled strut, mount, spring, and leveling kit engineered for the front position, so you get a bolt-in leveling solution rather than a loose parts pile. KYB builds corner-specific part numbers instead of a one-size-fits-all strut, because a strut assembly carries vehicle weight, sets ride height, acts as the steering pivot, and controls stability.
- Includes a KYB Excel-G strut with a stronger steel outer shell and KYB's application-specific precision-designed damping valves.
- Application-engineered KYB spring designed to match the strut, maintain proper ride height longer, and control weight without sacrificing ride quality.
- Designed to raise ride height approximately 2.5 inches while maintaining designed performance on your 2WD Nissan Frontier.
- Pre-assembled with all required hardware, and engineered to help vehicles with electronic safety systems (ESC, ABS, etc.).
Winner of the 2021 Best New Product award and assembled in the USA. Fitment: 2005-2021 Nissan Frontier — see the Buyer's Guide tab for the full application details.
