KYB Suspension Strut and Coil Spring Assembly P/N:SRG4131
$230.99

Take on work, towing, and off-road miles with the KYB Truck-Plus Performance Assembly SRG4131, a complete corner unit that combines the strut, mount, and coil spring into one pre-assembled piece. This is a front left assembly engineered as a direct-fit replacement for the 2003-2009 Toyota 4Runner and 2007-2009 Toyota FJ Cruiser. A strut assembly carries vehicle weight, sets ride height, acts as the steering pivot, and helps control stability, so KYB builds the Truck-Plus for exact fitment rather than a one-size-fits-all approach.

  • Gas-a-Just monotube: assembled with a KYB Gas-a-Just heavy-duty monotube shock absorber for added handling and control.
  • Application-engineered spring: a KYB spring matched to the strut to 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.
  • Safety-system aware: engineered to help vehicles equipped with electronic safety systems (ESC, ABS, etc.).

Built for trucks that work, go off-road, tow a trailer, or haul heavy loads, it delivers up to 25% more damping performance than standard shock absorbers on your Toyota. Assembled in the USA and pre-assembled for professional results. See the Buyer's Guide tab for engine-level fitment.
