|---|---|
| Position | Front Right |
| Installation Type | Screw-In |
| Finish Type | Powder Coated |
| Replaces part numbers | 63840EA800, NI1251127 |
This Parts N Go front right fender liner is an aftermarket, vehicle-specific replacement intended to protect the wheel well and engine bay from road debris and moisture. It installs using factory-style screw-in points and is finished with a powder coat for basic durability and corrosion resistance. In practice it serves as a direct substitute for the factory liner numbers listed, and most buyers report straightforward fits on compatible Frontier 4.0L trucks with only minor trimming or extra effort at the fender rim.

- Powder-coated finish for improved surface durability and corrosion resistance
- Uses screw-in installation compatible with factory mounting locations
- Replaces common manufacturer part numbers for clear fitment reference
- May require trimming, heat forming, or extra force to seat perfectly around the fender rim
- Does not consistently include new mounting hardware
Verdict A practical, vehicle-specific replacement fender liner that restores factory-style protection for reliability-minded owners, but plan for some adjustment during installation.

| Material | Plastic |
|---|---|
| Auto Part Position | Front |
| Fit Type | Vehicle Specific Fit |
| Model | TRQ BDA09984 Inner Fender Liner |

| Fit Type | Vehicle Specific Fit |
|---|---|
| Auto Part Position | Front |
| Material | Plastic |
| Manufacturer Part Number | JCWI222132GP |
| OEM Part Number | 63845EG000 |

Choosing the Right Infiniti FX35 Fender Liner: Key Factors to Consider
Fitment and Mounting Points
Correct fitment is the foundation of effective fender liner performance. A liner that matches factory mounting points prevents gaps where water and debris can enter, and avoids stress on clips and body panels. Poor alignment often leads to rubbing, rapid fastener wear, and the need for additional trimming or modification.
When assessing fitment, verify that the liner covers the wheel opening and follows the contour of the wheel well without forcing fasteners into awkward angles. Compatibility with the vehicle's original mounting hardware reduces installation time and helps maintain factory body seals. Accurate fitment also ensures that wheel articulation and suspension travel do not cause contact between the tire and liner.
Material Durability
Materials determine how well a liner resists impacts, UV exposure, and road chemicals. Thermoplastics and urethanes typically offer good flexibility to absorb minor impacts without cracking, while thinner plastics may become brittle over time.
Look for liners with resistance to road salt and oil, and that tolerate seasonal temperature swings. A durable material reduces the chance of long-term deformation or breakage, which preserves coverage and lowers the frequency of replacement.
Coverage and Protection Pattern
Not all liners provide the same coverage around suspension components, brake lines, and electrical harnesses. More complete coverage reduces the risk of corrosion and protects sensors and wiring from debris.
Assess whether the liner shields critical areas such as lower control arms and inner fender lips. Pay attention to designed cutouts or overlapping seams that maintain protection while permitting access to drain points or service areas.
Ease of Installation
Installation complexity affects how quickly you can get the liner in place and whether you will need specialized tools. Liners designed to use existing fasteners and clip locations typically install faster and with fewer additional parts.
Consider whether the liner requires trimming, drilling, or purchase of extra hardware. A straightforward install reduces the chance of incorrect attachment that can lead to rubbing or premature failure. Clear instructions and included fasteners are valuable for a smoother process.
Noise and Vibration Control
A well-designed liner can dampen road noise and prevent vibration-related buzzing in the wheel well area. Material thickness, attachment method, and fit all influence how much noise is absorbed versus transmitted into the cabin.
If noise reduction is a priority, look for liners with engineered ribs, soft mounting edges, or thicker panels in high-contact zones. Properly secured liners are less likely to vibrate loose and create intermittent sounds.
Service Access and Maintenance
Fender liners should allow reasonable access for routine maintenance like wheel removal, brake checks, and suspension inspections. Features such as access panels or strategically placed fasteners make service easier without complete removal.
Evaluate how the liner affects drainage and cleaning. Designs that trap water or debris can complicate maintenance and promote corrosion. Choosing a liner that balances protection with practical access will reduce labor time during repairs.
FAQ
How can I tell if my Infiniti FX35 fender liner needs replacement?
Look for visible cracks, large missing sections, or areas where the liner no longer attaches at the mounting points. You may also notice increased road noise, water spraying onto engine components, or debris collecting in the wheel well. If the liner is brittle or has warped away from the body, replacement is usually the safest option.
Is it necessary to use OEM fasteners when installing a fender liner?
Using OEM-style fasteners helps ensure correct fit and secure attachment, though many aftermarket kits specify compatible hardware. The important factor is that fasteners match the liner's mounting pattern and provide reliable retention to prevent movement and rubbing during driving.
Can I install a fender liner myself or should a technician do it?
Many liners are designed for owner installation with basic hand tools and a jack or lift for access. If the liner requires drilling, trimming, or access to tightly packaged areas, a technician may be a better choice. Consider your comfort level with underbody work and whether you have suitable tools and a safe workspace.
Will a new liner reduce road noise in the cabin?
A properly fitted and intact liner can help reduce some road noise by adding a barrier between the wheel well and the cabin. The degree of improvement depends on material thickness, attachment quality, and how well the liner covers the wheel opening. It is a helpful but not sole solution for noise control.
Do fender liners require regular maintenance?
Routine inspection is recommended, especially after off-road use or winter driving. Remove accumulated mud and debris periodically to prevent trapped moisture and corrosion. Tighten or replace loose fasteners during inspections to maintain proper coverage and performance.
How We Chose the Best Infiniti FX35 Fender Liner
We selected seven fender liners that meet strict fit and durability standards for the Infiniti FX35. Our evaluation prioritized accurate fitment to factory mounting points, material resilience against road salt and impacts, and design that preserves access to wheel wells and service panels. We also considered ease of installation, whether required hardware and fastener locations were supported, and the liner's resistance to common failure modes such as cracking or warping in heat. Noise dampening and how the liner channels water away from electrical components were additional quality signals. Exclusions included liners that required extensive trimming, non-dedicated universal shapes that sacrifice proper coverage, or products lacking clear mounting specifications. The resulting list emphasizes options that balance protection, longevity, and straightforward installation for this vehicle.
Our full evaluation process is outlined in our review methodology.
Conclusion
When choosing a fender liner for an Infiniti FX35, prioritize accurate fitment to factory mounting points and durable materials that resist road chemicals and temperature extremes. Balance comprehensive coverage with ease of installation and service access so the liner protects critical components without complicating routine maintenance. Tradeoffs are common: thicker materials improve durability and noise control but may add weight or complicate fitment, while lighter liners are easier to handle but may wear sooner. Focus on the factors that matter most to your driving conditions and maintenance preferences to make the best choice.
