KYB 15-20 Toyota Sienna AWD Strut-Plus Assembly - Front Left - SR4748

The KYB SR4748 Strut-Plus Assembly is a complete front left strut and coil spring assembly engineered specifically for the 2015–2020 Toyota Sienna AWD. Designed to meet OE standards, this ready-to-install unit simplifies the repair process by combining the strut and coil spring into a single, pre-assembled component — eliminating the need for a spring compressor and significantly cutting down shop labor time. If your Sienna is showing signs of worn suspension — bouncing, nose-dive under braking, uneven tire wear, or a generally vague steering feel — the KYB SR4748 is a direct-replacement solution purpose-built for your vehicle.

Key Features & Benefits

• Complete Strut-Plus Assembly: The strut and coil spring arrive pre-assembled, so there's no need to compress or swap springs at installation — saving time and reducing the risk of installation error.
• Engineered to KYB OE Standards: KYB designs this assembly to meet original equipment specifications, helping restore the ride quality and handling your Sienna had when it left the factory.
• AWD-Specific Fitment: This part is designed for all-wheel-drive Sienna models. Using a correctly matched strut for the AWD drivetrain helps ensure proper suspension geometry and alignment are maintained.
• Front Left Position: The SR4748 is the driver-side front strut. This precision-specific application means you get the correct valving and spring rate for that corner of the vehicle.
• Simplified DIY or Shop Installation: Because everything is pre-assembled, both professional technicians and experienced DIYers can complete the job more efficiently compared to replacing individual components.
• Restores Ride Comfort and Control: A worn strut affects everything from braking distance to cornering stability. Replacing with a fresh KYB unit helps bring back confidence-inspiring handling for daily driving and family hauling duties.

Frequently Asked Questions

Q: What years and drivetrains does the KYB SR4748 fit?

A: The SR4748 fits 2015 through 2020 Toyota Sienna models equipped with all-wheel drive (AWD) and the 3.5L V6 engine. It is the front left (driver-side) position only.

Q: Does this assembly include the coil spring, or just the strut cartridge?

A: The KYB Strut-Plus SR4748 is a complete assembly — it includes both the strut and the coil spring pre-assembled together. You will not need to transfer your old spring or use a spring compressor tool.

Q: Will this part fit my FWD Toyota Sienna?

A: No. The SR4748 is specifically designed for AWD Sienna models. If your Sienna is front-wheel drive, you will need a different part number. Confirm your drivetrain before ordering.

Q: Do I need to buy a matching right-side strut at the same time?

A: It is generally recommended by technicians to replace struts in pairs (both front left and front right at the same time) to maintain balanced handling and even ride quality across the axle. The SR4748 covers the front left position only, so you would want to source the corresponding front right assembly separately if replacing both sides.
