KYB Suspension Strut and Coil Spring Assembly P/N:SR4545
Bring back the factory ride and steering feel of your Toyota Sienna with the KYB Strut Plus Suspension Strut and Coil Spring Assembly (P/N: SR4155), a fully pre-assembled front left corner unit that drops into the 2007-2010 Toyota Sienna. As a complete strut and coil spring assembly, it combines the strut, mount and spring so you replace the whole worn corner at once.
A strut assembly carries vehicle weight, sets ride height, acts as the steering pivot and controls stability, and can affect a vehicle's electronic crash-avoidance systems. KYB, an original equipment supplier, engineers the Strut-Plus to help restore your Sienna's handling and control.
Fits the 2007-2010 Toyota Sienna (front left). See the Buyer's Guide tab for engine-level details.
