Bring back OE-level ride height, handling, and control on your 2005-2021 Nissan Frontier with the KYB Suspension Strut and Coil Spring Assembly SR4201 — a complete front corner unit that combines the strut, mount, and coil spring in one pre-assembled package. A strut assembly carries vehicle weight, sets ride height, acts as the steering pivot, and helps control stability, so this KYB Strut-Plus is engineered to help restore those handling and control capabilities.

  • Complete corner unit: includes a KYB Excel-G strut, upper mount, and coil spring — no separate spring compressor needed at install.
  • Application-engineered spring: high-carbon steel coil spring matched to the strut and corner weights to help maintain proper ride height without sacrificing ride quality.
  • Built to perform: a stronger steel outer shell and KYB's application-specific precision-designed damping valves.
  • Safety-system aware: engineered to help vehicles equipped with electronic safety systems (ESC, ABS, etc.). Assembled in the USA.

Named 2018 Best Overall Import Aftermarket Product and KYB's #1 recommended OE replacement choice for Asian vehicles. Fits the front position on the 2005-2021 Nissan Frontier — see the Buyer's Guide tab for engine-level detail.

Frequently Asked Questions

What is included in this assembly?

It is a complete front corner unit that comes pre-assembled with a KYB Excel-G strut, the upper mount, and an application-engineered coil spring.

Does this fit my Nissan Frontier?

It is a direct-fit front assembly for the 2005-2021 Nissan Frontier. Check the Buyer's Guide tab to confirm the engine and configuration for your vehicle.

Do I need a spring compressor to install it?

No. The strut, mount, and spring ship pre-assembled as one unit, so no separate spring compressor is required for the corner install.

How many should I buy?

This listing is for one assembly. For even, balanced handling it is best practice to replace both front struts as a matched pair.

What are the signs this strut assembly may need replacing?

Common signs include excessive bouncing, nose dive when braking, uneven tire wear, fluid leaking from the strut, or reduced ride height. Diagnose the cause before replacing.
