KYB 15-20 Toyota Sienna FWD Strut-Plus Assembly - Front Left - SR4746

The KYB SR4746 Strut-Plus Assembly is a complete front-left strut and coil spring assembly engineered specifically for the 2015–2020 Toyota Sienna FWD. Sold under KYB's Strut-Plus line, this ready-to-install unit combines the strut cartridge and coil spring into a single, pre-assembled package — eliminating the guesswork and spring-compression risk that comes with replacing components separately. If your Sienna is exhibiting nose dive during braking, uneven tire wear, a harsh or wallowing ride, or leaking strut fluid, the SR4746 is the front-left replacement designed to restore factory handling and ride comfort.

Key Features & Benefits

• Complete Strut-Plus Assembly: The strut cartridge and coil spring arrive pre-assembled as one unit, making installation faster and safer — no spring compressor tool required for reassembly, reducing DIY risk and shop labor time.
• KYB Quality Engineering: KYB is one of the world's largest OE suspension suppliers, and the Strut-Plus line is built to meet or exceed original equipment ride and handling specifications for the Sienna — helping restore the controlled, comfortable ride Toyota designed into this minivan.
• Vehicle-Specific Fitment: The SR4746 is engineered exclusively for the 2015–2020 Toyota Sienna in front-wheel-drive configuration, so you get a part that fits correctly without modification or shimming.
• Restored Ride & Handling Balance: A worn front strut causes the vehicle's nose to dive under braking, reduces steering response, and accelerates tire wear. Replacing with a fresh KYB assembly helps bring back the balanced, predictable handling the Sienna was designed to deliver.
• Convenient Single-Part Ordering: Buying a complete assembly means one part number, one box, and no need to source matching springs separately — simplifying both ordering and installation.

Frequently Asked Questions

Q: Does the SR4746 fit the all-wheel-drive (AWD) Toyota Sienna?
A: No — the SR4746 is specified for the front-wheel-drive (FWD) Sienna only, covering model years 2015 through 2020. If your Sienna has AWD, please reach out to us so we can identify the correct strut assembly for your vehicle.

Q: Is this a complete assembly, or do I need to source a separate coil spring?
A: This is a complete Strut-Plus assembly — the coil spring and strut are already combined into a single unit. You do not need to purchase a separate spring or use a spring compressor to rebuild the assembly.

Q: Do I need to replace both front struts at the same time?
A: While this listing covers the front left position only, most suspension professionals recommend replacing struts in pairs (both front or both rear) to maintain balanced ride and handling characteristics. A separate part number is available for the front right position — contact us and we can help you find the matching unit.

Q: Will I need a wheel alignment after installing this strut assembly?
A: Strut replacement typically affects front-end alignment geometry. It is strongly recommended to have a professional wheel alignment performed after installing new front strut assemblies to ensure proper tire wear and handling.
