Detailed Fitment

Compatible with 2003-2008 Infiniti FX35 rear suspension and 2003-2008 Infiniti FX45 rear suspension, this shock absorber is intended for vehicles that need a replacement unit matched to the original mounting location and travel range. The FCS 8341631RL part number should be verified against the existing component before ordering, especially when comparing suspension assemblies with different dimensions or mounting details. For Infiniti FX35 and Infiniti FX45 applications, the listed fitment and measurements help confirm the correct rear shock absorber selection.

What It Helps Fix

  • Excessive bouncing after bumps or dips.
  • Reduced control from worn rear damping.
  • Uneven ride quality caused by tired suspension components.
  • Noisy or unstable rear suspension behavior.
