KYB 15-20 Toyota Sienna FWD Strut-Plus Assembly - Front Right - SR4745

The KYB SR4745 Strut-Plus Assembly – Front Right is a direct-fit front strut replacement engineered specifically for 2015–2020 Toyota Sienna FWD models. If your Sienna's ride has become bouncy, wandering, or just plain worn out, replacing the front strut with a KYB Strut-Plus Assembly restores the handling confidence and smooth ride your minivan had when it left the factory. This is a complete, pre-assembled strut unit — not a bare strut — making it one of the most practical suspension upgrades available for the third-generation Sienna.

Key Features & Benefits

• Pre-Assembled Strut-Plus Design: The SR4745 arrives as a complete assembly, meaning less time fighting with spring compressors and more time on the road. This dramatically reduces installation complexity and minimizes the risk of install errors.
• Engineered to Meet or Exceed OE Standards: KYB is a well-known original equipment supplier to vehicle manufacturers globally, and uses the same materials and techniques for its aftermarket products — so this unit is built to restore your Sienna's ride to factory-like performance rather than simply patch it.
• Restores Original Handling & Control: Over time, struts lose their damping ability, leading to excessive body roll, longer stopping distances, and uneven tire wear. The SR4745 is designed to bring back the precise handling and stability characteristics the Sienna was tuned for at the factory.
• Durable Construction for Long Service Life: Components are built from durable materials intended for enhanced longevity, reducing the frequency of repeat repairs — an important consideration for a high-mileage family hauler like the Sienna.
• Specific to Front Right Position: The SR4745 is the front right strut assembly. The companion front left is SR4746. Buying the correct side-specific unit ensures proper geometry and alignment after installation.
• KYB's Safety-First Philosophy: KYB builds products with vehicle control, stability, and stopping distance in mind — qualities that matter especially for a family minivan carrying passengers daily.

Frequently Asked Questions

Q: Does the SR4745 fit AWD versions of the 2015–2020 Toyota Sienna?
A: No — the KYB SR4745 is specifically engineered for the Front-Wheel Drive (FWD) Sienna. If your Sienna is equipped with All-Wheel Drive, this part number may not be the correct fit. Check your vehicle's drivetrain configuration before ordering, or contact ThreePiece.us for confirmation.

Q: Is this the complete strut assembly, or do I need to buy a spring separately?
A: The SR4745 is a Strut-Plus Assembly, meaning it is a pre-assembled unit — not a bare strut cartridge. This design is intended to simplify installation significantly compared to building up individual components. If you need specifics on every included component, reach out to our team before ordering.

Q: Do I need to buy the left side separately?
A: Yes. The SR4745 covers the front right position only. The front left strut assembly for the same application is sold separately under KYB part number SR4746. It is generally recommended to replace front struts in pairs to maintain balanced handling and even ride quality.

Q: Can I use Affirm to finance this purchase?
A: Yes — Affirm financing is available at checkout on ThreePiece.us, allowing you to spread the cost of this repair over time. Free shipping is included on every order regardless of payment method.
