Help restore front-right ride height and steady handling with the KYB Strut-Plus Suspension Strut and Coil Spring Assembly (SR4633), a pre-assembled complete corner unit — strut, mount and spring — built as a direct-fit front right (passenger-side) replacement. It fits many vehicles, among them the 2015 Infiniti Q40, 2009-2013 Infiniti G37 and 2011-2012 Infiniti G25. See the Buyer's Guide tab for the full list and engine-level fitment.

As an original-equipment supplier, KYB builds this assembly on an OE-restoring strut so it's engineered to help return the handling and control your Infiniti had when new.

  • KYB Excel-G strut: a stronger steel outer shell with KYB's application-specific, precision-designed damping valves.
  • Application-engineered spring: high-carbon steel coil springs developed around vehicle attributes and corner weights to help hold proper ride height within OE specifications.
  • Side-specific design: left and right part numbers with side-specific components, as the vehicle manufacturer intended — this is the front right unit.
  • Exact-fit and pre-assembled: engineered for exact fitment and pre-assembled for professional results, and engineered to help vehicles with electronic safety systems (ESC, ABS, etc.).

KYB's #1 recommended OE replacement choice for Asian vehicles.

Frequently Asked Questions

What position does the SR4633 fit?

It is the front right (passenger-side) complete corner unit. KYB uses side-specific components, so order the matching part number for the opposite corner.

Which vehicles does this fit?

It fits many vehicles, among them the 2015 Infiniti Q40, 2009-2013 Infiniti G37 and 2011-2012 Infiniti G25. See the Buyer's Guide tab for the full list and engine-level fitment.

Is this a complete strut and coil spring assembly?

Yes. It ships pre-assembled with the KYB Excel-G strut, mount and application-engineered spring, so no separate spring compression is needed at install.

What kind of spring does it use?

A high-carbon steel coil spring developed around the vehicle's attributes and corner weights to help maintain ride height within OE specifications.

What are signs this strut assembly may need replacing?

Excessive bounce, sagging ride height, uneven tire wear, or reduced stability and control. Have the cause diagnosed, since these signs can involve other suspension parts too.
