Restore original ride height and factory-tuned handling with the KYB Strut-Plus Suspension Strut and Coil Spring Assembly SR4431, a complete front-left corner unit that bundles the strut, mount, and spring into one pre-assembled part. It drops in as a direct-fit replacement for the 2009-2013 Honda Fit and 2010-2014 Honda Insight (see the Buyer's Guide tab for engine-level applications). As an original-equipment supplier, KYB engineers this unit to help bring back the handling and control your vehicle had when new.
A strut assembly supports vehicle weight, sets ride height, serves as the steering pivot, and influences stability. Pre-assembled for professional results and assembled in the USA, this named a Best Overall Import Aftermarket Product winner and is KYB's #1 recommended OE replacement choice for Asian vehicles.
What vehicles does the KYB SR4431 fit?
It's a direct-fit front-left corner assembly for the 2009-2013 Honda Fit and 2010-2014 Honda Insight. Check the Buyer's Guide tab to confirm the application for your specific vehicle.
What comes in this assembly?
It's a complete corner unit — the KYB Excel-G strut, the mount, and an application-engineered high-carbon steel coil spring, all pre-assembled and ready to install.
Which corner is this unit for?
This is the FRONT LEFT unit. KYB uses left and right part numbers with side-specific design and components, so order the matching part number for the opposite corner.
Does this work with vehicles that have ESC or ABS?
Yes. It's engineered to help vehicles equipped with electronic safety systems such as ESC and ABS function as intended.
Should I replace both sides at once?
Replacing struts as a pair on the same axle is a common best practice for balanced, even handling, though it isn't strictly required. This listing covers the front-left unit only.
