Put truck-tuned ride control back in your corner with the KYB Suspension Strut and Coil Spring Assembly SRG4130, a complete front-right corner unit that pairs the strut, upper mount, and an application-engineered coil spring in one pre-assembled piece. It installs as a direct-fit replacement on the 2003-2009 Toyota 4Runner and 2007-2009 Toyota FJ Cruiser, ready to bolt into place.
A strut assembly carries vehicle weight, helps set ride height, acts as the steering pivot, and helps control vehicle stability, so KYB builds the Truck-Plus for trucks that work, go off-road, tow a trailer, or haul heavy loads.
- Gas-a-Just monotube: assembled with a KYB Gas-a-Just heavy-duty monotube shock absorber for additional handling and control — up to 25% more damping performance than standard shock absorbers on your Toyota.
- Matched spring: application-engineered 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 — this is the front-right unit — as the vehicle manufacturer intended.
- Assembled in USA and engineered to help vehicles with electronic safety systems (ESC, ABS, etc.).
Signs this corner may need replacing include excessive bounce, uneven ride height, clunking over bumps, or fluid leaking from the strut.
