2. Monroe Quick-Strut 172370 Complete Strut Assembly for Infiniti FX35
| Auto Part Position | Front |
|---|---|
| Compatible with Vehicle Type | Truck |
| Automotive Fit Type | Vehicle Specific Fit |
| Material Type | Alloy Steel |
The Monroe Quick-Strut 172370 is a complete front strut assembly engineered specifically for the 2003–2008 Infiniti FX35 to simplify replacement and restore factory ride and handling. It arrives fully assembled with the strut, coil spring, and upper mount installed so you do not need a spring compressor during installation, which reduces labor time and safety risk. Monroe specifies application-specific coil springs to return proper ride height and uses a robust tube and weld design with a protective coating for corrosion resistance. In real-world use this yields firmer, more controlled cornering, reduced body sway and improved steering feel compared with worn original units. Because it is vehicle-specific and includes mounting hardware, alignment is the typical follow-up service to ensure correct tire wear and steering geometry. Trade-offs are that a full assembly can be heavier and more expensive than replacing only internal strut components, and installation still requires standard suspension tools and alignment afterward.
Best for: Performance-oriented owners who prioritize restoring factory handling and steering precision on a 2003–2008 Infiniti FX35 and prefer a ready-to-install, vehicle-specific solution that reduces installation complexity.
Less Ideal for: Buyers looking for the lowest-cost repair or who only need to replace a single strut component should consider separate components or rebuild options instead.
- Comes fully assembled with strut, coil spring, and mount for faster, safer installation
- Application-specific coil spring restores factory ride height and handling
- Durable steel tube and weld construction with protective coating for corrosion resistance
- Includes mounting hardware so fewer additional parts are required
- Full assembled units are typically more costly than replacing individual components
- Requires post-installation wheel alignment to prevent premature tire wear
Verdict: A ready-to-install, vehicle-specific strut assembly that restores ride height and handling for the Infiniti FX35 while simplifying replacement.

Choosing the Right Infiniti FX35 Quick Struts: Key Factors to Consider
Fitment and Vehicle Match
Correct fitment is the most important factor because quick struts must align with the suspension geometry and mounting points unique to the Infiniti FX35. An assembly that bolts in without modification preserves ride height, wheel alignment, and steering response. Poor fitment can lead to premature wear of tires, uneven suspension loading, and added stress on control arms.
When evaluating fitment, check that the assembly is listed specifically for the Infiniti FX35 and that it covers the correct model years and front or rear position. Choosing a direct-fit assembly reduces installation time and the need for additional parts or adjustments.
Damping Performance and Spring Rate
Damping behavior and spring rate determine how the vehicle controls body motions from bumps, turns, and braking. A quick strut with appropriate damping for the FX35 will keep the ride composed while preventing excessive oscillation after bumps. Spring rate affects ride height and load carrying capacity, so a mismatch can alter handling balance and comfort.
Look for assemblies whose damping characteristics are described for passenger comfort or performance as needed, and ensure the spring rate matches stock or intended use to avoid unexpected changes in ride dynamics.
Build Quality and Materials
Durable materials and solid construction help strut assemblies withstand road salt, water, and daily wear. Corrosion-resistant coatings, robust welds, and high-quality seals extend service life and maintain damping performance. Inferior materials can lead to leaks, reduced damping, and structural failures over time.
Assess the quality of the cartridge, piston rod finish, and mounting plates. Reinforced strut mounts and properly seated bearings reduce noise and improve longevity under repeated steering and suspension loads.
Mounting Components and Completeness
One advantage of quick struts is that they come pre-assembled with mounts, bearings, and insulators. A complete assembly reduces labor and eliminates the need to reuse worn components. If the top mount or bearing is degraded, reusing it can cause noise, poor steering feedback, and premature failure.
Verify that the assembly includes the necessary mount hardware for front or rear positions on the Infiniti FX35 and that the parts are matched to the vehicle's suspension layout to ensure a seamless replacement process.
Corrosion Protection and Environmental Resistance
Struts are exposed to grit, salt, and moisture, so corrosion protection is crucial for long life. Treatments such as powder coating, zinc plating, or protective boots help prevent rust on the strut body and piston rod. Corrosion can impair seal performance and lead to loss of damping.
Consider the local climate and road conditions when prioritizing corrosion resistance. Assemblies with robust protective finishes and durable dust boots will typically last longer in harsh environments.
Warranty and Manufacturer Support
A clear warranty indicates manufacturer confidence in materials and workmanship and provides recourse if an assembly fails prematurely. Warranty terms vary in length and coverage, so understand what components are protected and any installation requirements.
Good manufacturer support can also help with fitment questions and ensure replacement parts are available if needed. Favor assemblies backed by clear documentation and responsive support channels.

FAQ
How do I know when my Infiniti FX35 needs quick struts?
Common signs include excessive bouncing after bumps, poor control during cornering, increased nose dive under braking, uneven tire wear, or audible clunks from the suspension. These symptoms often point to worn damping components or failing mounts, which quick struts are designed to address.
Are pre-assembled quick struts easier to install than rebuilding old struts?
Yes, pre-assembled quick struts save time because they arrive with the spring, mount, and bearing already installed. That reduces the need for spring compressors and minimizes labor for most installations. However, installation still requires proper tools and attention to torque specs to ensure safe fitment.
Can I replace only the front or only the rear struts on the Infiniti FX35?
You can replace just the front or just the rear assemblies if only one end is worn, but handling balance may change if the opposite corner is significantly older. It is usually best to assess both sides on the same axle and consider replacing pairs to maintain consistent ride and response.
Will new quick struts affect wheel alignment?
Replacing quick struts can change alignment angles slightly due to restored ride height or different mounting tolerances. It is common and advisable to perform a wheel alignment after strut replacement to ensure correct camber, toe, and caster for stable handling and even tire wear.
How long do quick struts typically last on a vehicle like the Infiniti FX35?
Longevity depends on driving conditions, climate, and usage. Under normal driving, strut assemblies commonly last many tens of thousands of miles, but exposure to heavy road salt, rough roads, or frequent heavy loads can shorten service life. Watch for progressive symptoms rather than relying solely on mileage.
Conclusion
When replacing Infiniti FX35 quick struts, prioritize correct fitment, damping behavior, and the completeness of the pre-assembled unit to minimize installation time and restore predictable handling. Consider build quality and corrosion protection if you drive in harsh conditions, and review warranty terms for added assurance.Balancing ride comfort and control means accepting tradeoffs between firmer damping and softer compliance. Address both front and rear condition as needed and plan for a post-installation alignment to ensure the best long-term performance.
