Is this a front or rear strut assembly?
This is the rear left corner unit. It carries a side-specific part number with side-specific components, so be sure to order the correct side for your vehicle.
Does this KYB quick strut assembly come pre-assembled?
Yes. As one of KYB's complete struts, it ships as a pre-assembled corner unit with the strut, mount, and spring together for exact, professional-ready fitment.
What is included in this complete strut and coil spring assembly?
It includes a KYB Excel-G strut with a stronger steel outer shell and precision-designed damping valves, an upper mount, and an application-engineered high-carbon steel coil spring.
Should I replace both sides at the same time?
Struts wear together, so replacing the matching side as a pair is recommended for balanced, even handling. This listing covers the single rear left assembly.
