KYB SRG4529 Suspension Strut and Coil Spring Assembly - Front Left

KYB Truck-Plus Front Left Strut Assembly

The KYB Truck-Plus Performance Assembly SRG4529 is a front left suspension strut and coil spring assembly for select Toyota trucks and SUVs. It is built for the vehicle’s weight, ride height, steering pivot function, and stability control demands, making it a direct replacement for applications that need more than a generic, one-size-fits-all part.

Compatible with 2010-2023 Toyota 4Runner front left models without X-REAS suspension, and 2010-2014 Toyota FJ Cruiser front left models, this assembly is a fitment-specific solution for common front suspension service needs. The KYB Truck-Plus line focuses on application-matched performance for truck and SUV platforms, and SRG4529 is part of that dedicated product line.

Detailed Description

KYB SRG4529 is engineered as a complete front left strut and coil spring assembly for Toyota 4Runner and Toyota FJ Cruiser applications that require a precise suspension match. The assembly dimensions, including 17.57-inch compressed length, 21.81-inch extended length, and 4.24-inch stroke, support proper suspension travel and ride-height control for the listed vehicles. The included boot adds protection for the strut shaft area.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application. Use SRG4529 when servicing the front left suspension on a 2010-2023 Toyota 4Runner without X-REAS suspension or a 2010-2014 Toyota FJ Cruiser with the listed performance upgrade configuration. The part number SRG4529 should be verified against the vehicle’s suspension setup before installation.

What It Helps Address

• Front-end ride height changes from worn suspension components
• Excessive bounce or reduced damping control
• Steering response issues caused by worn strut assemblies
• Suspension noise from aging front left components
• Stability concerns on Toyota 4Runner and Toyota FJ Cruiser front suspension service

Installation Notes and Tips

Confirm the vehicle is a front left application and verify whether the 4Runner is equipped without X-REAS suspension before ordering. Compare the original assembly dimensions and mounting configuration to SRG4529, and inspect related suspension parts such as mounts, springs, and hardware condition during service. Because this is a strut and coil spring assembly, proper suspension handling procedures and alignment checks are recommended after installation.

Quality Assurance

KYB designs the Truck-Plus Performance Assembly as an application-specific replacement for truck and SUV suspension systems, with attention to the load, steering, and stability demands of the vehicle platform. SRG4529 is built for the listed Toyota fitments and follows KYB’s focused approach to suspension replacement parts.
