KYB Suspension Strut and Coil Spring Assembly P/N:SRG4529

Rebuild your truck's front-left corner in one pre-assembled step with the KYB Truck-Plus Performance Assembly SRG4529, a complete strut, mount, and coil spring unit. It's engineered for the front-left position on the 2010-2023 Toyota 4Runner and 2010-2014 Toyota FJ Cruiser — see the Buyer's Guide tab for the full engine breakdown. A strut assembly handles vehicle weight, sets ride height, acts as the steering pivot, and helps control stability, so KYB builds the Truck-Plus with exact, application-engineered fitment rather than a one-size-fits-all part.

• Gas-a-Just monotube: assembled with a KYB Gas-a-Just heavy-duty monotube shock absorber for additional handling and control.
• Application-engineered spring: a KYB spring designed to match the strut, help maintain proper ride height longer, and control weight without sacrificing ride quality.
• Side-specific design: left and right part numbers with side-specific components, as the vehicle manufacturer intended.
• Up to 25% more damping: offers up to 25% more damping performance than standard shock absorbers on your Toyota 4Runner and FJ Cruiser.

Engineered to help vehicles equipped with electronic safety systems (ESC, ABS, etc.) and built for trucks that work, go off-road, tow a trailer, or haul heavy loads.
