KYB 340021 front left suspension strut assembly for the 2015 Infiniti Q40 and other vehicles helps manage tire contact, steering response and body movement. This KYB strut assembly is made on KYB's own OE assembly lines and calibrated to restore original, designed performance rather than change it.
- Excel-G line strut with a nitrogen gas-charged, twin-tube design
- Vehicle-specific, hand-assembled damping valves
- Triple lip fluid seal to reduce the chance of oil and gas leaking out
- Thick strut body and brackets that minimize flex and help hold correct alignment
- Internal anti-rollover spring, which may make the extended length appear shorter
Quick facts

A bouncy or floating ride, nose dive under braking or oil on the strut body can mean this strut is worn, though an unbalanced tire or a tired sway bar link can produce a similar feel.
Fits
The vehicles it fits include the 2015 Infiniti Q40, the 2009-2013 Infiniti G37 and the 2011-2012 Infiniti G25.

Frequently Asked Questions
Is the KYB 340021 front strut assembly right for the 2015 Infiniti Q40?
Yes. KYB 340021 is the front left strut assembly for the 2015 Infiniti Q40, and this side takes one. Open the "Vehicles it fits" section to check other models and engines.
Does this KYB suspension strut work on a 2009-2013 Infiniti G37?
Yes. KYB 340021 fits the 2009-2013 Infiniti G37 at the front left, and the front right takes its own separate strut.
What design is the KYB Excel-G strut assembly?
The Excel-G is a nitrogen gas-charged, twin-tube design. It uses a triple lip fluid seal to reduce the chance of oil and gas leaking out.
Does oil on the body of a KYB suspension strut assembly mean it needs replacing?
It can mean the strut is worn, so have it inspected promptly. A bouncy ride or nose dive under braking can also point to wear, and a shop can confirm it.
Why does the extended length of this front left strut look short?
This strut has an internal anti-rollover spring, which may cause the extended length to appear shorter.
