Restore composed ride height and controlled handling at the rear-left corner with the KYB Strut-Plus Suspension Strut and Coil Spring Assembly SR4424, a complete corner unit that drops in as a direct-fit replacement for the 2006-2014 Honda Ridgeline. A strut assembly supports vehicle weight, sets ride height, serves as the steering pivot, and helps control vehicle stability — and it can affect electronic crash-avoidance systems. As an OE supplier, KYB builds the Strut-Plus around an Original Equipment Restoring strut to help bring back your Ridgeline's factory handling and control.
- OE Restoring strut: includes a KYB Excel-G strut with a stronger steel outer shell and KYB's application-specific, precision-designed damping valves.
- High-carbon steel coil spring: application-engineered to match the strut, help maintain ride height within OE specifications, and control weight without sacrificing ride quality.
- Side-specific build: left and right part numbers with side-specific design and components, as the vehicle manufacturer intended.
- Pre-assembled: exact-fitment engineered and pre-assembled for professional results; engineered to help vehicles with electronic safety systems (ESC, ABS, etc.).
Winner of Best Overall Import Aftermarket Product and KYB's #1 recommended Original Equipment replacement choice for Asian vehicles.

Frequently Asked Questions
What vehicle does this KYB SR4424 fit?
It's a direct-fit replacement for the 2006-2014 Honda Ridgeline at the rear-left corner. See the Buyer's Guide tab to confirm your exact application.
What comes in this assembly?
It's a complete corner unit: a KYB Excel-G strut with a stronger steel outer shell, a matched high-carbon steel coil spring, and the mount — pre-assembled and ready to install.
Which corner is this strut for?
This SR4424 is the rear-left (driver-side rear) assembly. KYB uses left and right part numbers with side-specific design, so order the correct side for your vehicle.
Will it work with my Ridgeline's electronic safety systems?
Yes. The Strut-Plus is engineered to help vehicles with electronic safety systems such as ESC and ABS, since strut condition can affect these systems.
Should I replace both rear struts at once?
Replacing struts as a pair is a good practice for balanced ride and handling. This listing covers the rear-left corner only; order the opposite side separately if needed.
