KYB Suspension Strut and Coil Spring Assembly P/N:SR4521

$264.99

Description

The KYB Strut Plus SR4521 helps restore the ride height, handling, and control your suspension had when new, arriving as a fully pre-assembled front-left complete strut and coil spring assembly. It drops in as a direct-fit replacement for the 2011-2016 Scion tC and 2012-2017 Toyota Prius V, pairing a KYB Excel-G strut, mount, and application-engineered spring in one corner unit. KYB builds it starting from an OE-restoring strut, with side-specific components carried as left and right part numbers just as the vehicle manufacturer intended.

OE-restoring damping: Includes a KYB Excel-G strut with a stronger steel outer shell and application-specific precision-designed damping valves.
Matched coil spring: High-carbon steel coil springs developed around the vehicle's attributes and corner weights help keep ride height within OE specifications while controlling weight without sacrificing ride quality.
Electronic-safety aware: Engineered to help vehicles equipped with electronic safety systems such as ESC and ABS.
Pre-assembled convenience: Exact-fitment engineered and factory pre-assembled for professional, ready-to-install results.

Signs the original strut may need replacing include excessive bouncing, nose-dive under braking, uneven tire wear, or a sagging, uneven ride height. This is a KYB complete strut for the front-left corner.

Frequently Asked Questions

What is the KYB strut plus assembly SR4521?

It's a KYB Strut Plus front-left strut assembly, combining an Excel-G strut, mount, and application-engineered high-carbon steel coil spring pre-assembled into one ready-to-install unit.

Which vehicles does this KYB quick strut assembly fit?

It's a direct-fit replacement for the 2011-2016 Scion tC and 2012-2017 Toyota Prius V. See the Buyer's Guide tab to confirm your exact vehicle.

Is this a front or rear strut, and which side?

This is a front-left assembly. KYB uses side-specific part numbers with side-specific design and components, so order the number matching your corner.

Do I need to replace both KYB front strut assemblies together?

This listing is for one front-left assembly. Replacing struts in axle pairs is a common best practice for balanced handling, though it isn't strictly required.

What are the signs my strut needs replacing?

Common signs include excessive bouncing, nose-dive under braking, uneven or cupped tire wear, and a sagging or uneven ride height. Diagnose the cause before replacing.
