KYB Suspension Front Struts and Rear Shocks / Coil Springs / Trailing Arm Kit

KYB Suspension: Complete Strut, Coil Spring & Trailing Arm Solutions

When it comes to restoring your vehicle's suspension to factory-spec performance, few names carry the credibility of KYB Suspension. As a Tier 1 original equipment supplier to major automakers, KYB engineers suspension components with an intimate understanding of how a vehicle is supposed to ride, handle, and respond — and that expertise is baked into every front strut, rear shock, and coil spring assembly they produce.

KYB's flagship offering in the Front Struts, Rear Shocks, Coil Springs & Trailing Arm Kit category is the Strut-Plus complete strut assembly. Rather than selling a strut alone and leaving the installer to source and compress individual coil springs, mounts, and hardware, KYB bundles everything into a single pre-assembled unit. No spring compressor is required — a significant safety advantage that also dramatically reduces installation time for both professional technicians and experienced home mechanics.

What Sets the KYB Strut-Plus Apart

The Strut-Plus assembly is built around the proven KYB Excel-G twin-tube gas strut, featuring a stronger steel outer shell and application-specific, precision-engineered damping valves assembled by hand in-house. The entire unit ships pre-loaded with the correct spring, top mount, and insulators matched specifically to the vehicle application — so every component is calibrated to work together from the moment it leaves the box.

• Application-engineered coil springs: High carbon steel coil springs are developed around individual vehicle attributes and corner weights, helping restore ride height within OE specifications. After an annealing process, KYB springs receive a zinc phosphate coating and epoxy powder resin paint for industry-leading corrosion protection.
• OE-matched damping valves: Hand-assembled in-house to restore original handling and stability, ensuring compatibility with modern electronic safety systems such as Electronic Stability Control (ESC) and ABS.
• Side-specific design: Left and right components feature distinct part numbers with side-specific engineering, just as the vehicle manufacturer intended.
• Calibrated for worn suspensions: Components are calibrated to compensate for the wear patterns common in aging suspensions, not just match a brand-new vehicle baseline.
• Comprehensive warranty: KYB struts and Strut-Plus assemblies are backed by a lifetime limited warranty for the original purchaser, with coil springs and hardware covered for one year.

Why the Complete Assembly Approach Matters

A strut assembly does far more than cushion bumps — it bears vehicle weight, determines ride height, serves as the steering pivot, and directly influences the performance of crash avoidance electronics. Replacing just the strut while leaving behind a worn or mismatched spring and mount can compromise alignment, reduce tire life, and interfere with safety systems. KYB's Strut-Plus addresses this by delivering a complete, cohesive corner unit engineered as a system, not a collection of parts.

For drivers seeking a reliable, precision-fit solution that eliminates guesswork and reduces garage time, KYB's front strut, rear shock, coil spring, and trailing arm assemblies represent one of the most thorough approaches to suspension restoration available on the market today.
