FAQ
What is the KYB3438020?The KYB3438020 is an Excel-G rear shock absorber built for the Nissan Leaf. It uses OE spec valving in a gas charged twin tube design to restore factory ride comfort without changing ride height.
Is this a direct replacement or will I need extra parts?It's a direct bolt-on replacement that installs at the factory shock mounting points without modification.
Do I need to replace both rear shocks at once?It's sold individually, but replacing both sides together is recommended for even handling.
Will this handle the extra weight of the battery pack okay?Yes, it's engineered to OE specifications that already account for the Leaf's curb weight, including the battery pack.
Does it come with any kind of warranty?Yes, it's backed by KYB's standard limited warranty covering manufacturing defects.
Do I need any special tools to install it?No, standard hand tools are enough since it bolts into the factory shock location.
Will this change how the car rides compared to stock?It's designed to match the factory ride feel, so you shouldn't notice a dramatic difference beyond restored damping.
Is there a break-in period after installing new shocks?No formal break-in is required, though damping performance can feel slightly firmer for the first several miles as components settle.
