Choosing OEM vs Aftermarket Tailgate Cables
Choosing OEM vs Aftermarket Tailgate Cables
When it comes to replacing your truck or SUV’s tailgate cables, the immediate question is whether to choose Original Equipment Manufacturer (OEM) or aftermarket cables. The right decision impacts load capacity, fitment, and the long-term safety of your vehicle. This comprehensive AutoPartEx guide provides a clear, practical comparison of OEM vs aftermarket tailgate cables, addresses hidden pitfalls, and gives you a step-by-step approach to selecting and installing the right cables for your needs.

Immediate Answer: OEM vs Aftermarket Tailgate Cables—What’s the Difference?
OEM tailgate cables are made or specified by the vehicle’s manufacturer and designed to meet all original load, fitment, and safety standards. Aftermarket tailgate cables are produced by third-party companies and may offer broader compatibility, lower prices, or upgraded materials, but can vary widely in quality and fit.
Quick Comparison Table:
| Feature | OEM Cables | Aftermarket Cables |
|---|---|---|
| Fitment | Guaranteed (vehicle-specific) | Varies (vehicle-specific or universal) |
| Load Rating | Meets/exceeds original specs | Varies; check product documentation |
| Material Quality | Consistent, tested materials | Can range from high to low |
| Price | Typically higher | Often lower, but varies |
| Availability | Dealer or authorized suppliers | Wide range of retailers |
| Warranty | Usually matches original part warranty | Varies by manufacturer |
The Hidden Problem: Not All Tailgate Cables Are Created Equal
While tailgate cables might seem like simple components, their failure can lead to serious safety risks, including sudden tailgate drops, lost cargo, or even injuries. The National Highway Traffic Safety Administration (NHTSA) recognizes tailgate support cables as critical safety equipment, subject to equipment and recall standards [1]. The hidden issue is that not all cables—especially in the aftermarket—are built to the same technical or safety standards. Some may lack proper corrosion resistance, tensile strength, or precise fitment, leading to premature failure or improper operation.
Deeper Technical Explanation: How Materials and Manufacturing Affect Performance
Material Technologies and Load Capacity
Tailgate cables are subjected to repeated loading, environmental exposure, and mechanical stress. The U.S. Department of Energy highlights the importance of advanced materials technologies in automotive components, noting that strength, corrosion resistance, and weight all play a role in long-term durability and vehicle performance [2]. OEM cables typically use galvanized or stainless steel wire rope, crimped with engineered end fittings and coated with a UV-resistant sheath. Aftermarket cables may use similar or alternative materials, but quality can vary:
- Steel grade and diameter: Impacts tensile strength and load rating.
- Coating: Affects resistance to abrasion, moisture, and road salts.
- End fittings: Precision machining and corrosion protection are crucial for secure attachment.
Engineering and Testing Standards
OEM parts are designed to meet original vehicle engineering and SAE standards for load, fatigue cycles, and environmental resistance. Aftermarket cables may or may not adhere to these standards; always look for documentation or certification where possible.
Fitment: Why Precision Matters
Vehicle-Specific vs Universal Fit
OEM cables are always vehicle-specific, ensuring exact length, end fitting geometry, and mounting hole alignment. This guarantees that your tailgate opens to the correct angle and supports the intended load. Aftermarket cables may be vehicle-specific or universal:
- Vehicle-specific aftermarket: Designed for a particular make/model/year, often mirroring OEM specs.
- Universal: One-size-fits-many, but may require adjustment or compromise on fit or function.
Risks of Poor Fitment
A cable that is too long may cause the tailgate to open too far, stressing hinges or bodywork. A cable that is too short may prevent full tailgate opening or place excess force on attachment points, risking premature failure.
Load Capacity: Understanding Ratings and Real-World Limits
How to Read Load Ratings
Both OEM and quality aftermarket cables will specify a working load limit (WLL) and an ultimate breaking strength. The WLL is the maximum safe load, typically a fraction (often 1/5 or 1/10) of the breaking strength, to account for dynamic forces and fatigue over time.
- OEM cables: Load rating matches the vehicle’s original design. For most pickups, this ranges from 300 to 600 lbs per cable.
- Aftermarket cables: Always check packaging or product documentation. Some may not specify a WLL—avoid these.
Consequences of Exceeding Load Ratings
Overloading the tailgate can cause cable stretching, fraying, or sudden failure. Always consider the combined load of the tailgate, cargo resting on it, and any dynamic forces (e.g., sitting or standing on the open tailgate).
Lifespan and Durability: What to Expect
Factors Affecting Cable Life
- Material quality: Stainless steel resists corrosion best; galvanized steel is also common.
- Coating integrity: Cracked or missing coatings accelerate rust and cable fatigue.
- Environmental exposure: Road salt, moisture, and UV rays degrade cables over time.
- Load cycles: Frequent heavy loading shortens lifespan.
OEM vs Aftermarket Durability
OEM cables are tested for thousands of open/close cycles and years of exposure. Premium aftermarket cables may match or exceed this, but budget options may use lower-grade materials. Always inspect for signs of fraying, rust, or deformation—see our Top Signs Your Tailgate Cable Needs Replacement for a detailed checklist.
Installation: What You Need to Know
Tools and Preparation
- Basic tools: Socket set, torx or hex drivers, pliers.
- Safety gear: Gloves, eye protection.
- Replacement cables: Confirm part number and compatibility.
Step-by-Step Overview
- Support the tailgate to prevent sudden drops.
- Remove fasteners securing the old cable at both ends.
- Inspect mounting points for rust or damage; clean or repair as needed.
- Install the new cable, ensuring correct orientation and secure attachment.
- Test tailgate operation for smooth, full opening and proper support.

Maintenance: Maximizing Tailgate Cable Lifespan
Regular Inspection Checklist
- Visual check: Look for frayed wires, bulges, or exposed metal.
- Coating: Ensure plastic/rubber sheath is intact and flexible.
- End fittings: Check for corrosion, cracks, or looseness.
- Attachment points: Tighten bolts and lubricate as needed.
Preventive Care
- Rinse cables regularly if you drive in salty or muddy environments.
- Avoid exceeding the load rating with people or heavy cargo.
- Replace cables in pairs to maintain balanced support.
Safety and Compliance: Meeting Regulatory Standards
The NHTSA classifies tailgate cables as safety equipment, and failures may be subject to recalls or safety bulletins [1]. OEM cables and most reputable aftermarket brands design to meet or exceed these standards, but unbranded or low-cost imports may not. Always verify that your replacement cable is rated for your vehicle and meets safety regulations.
If you suspect a defect or experience a sudden failure, check for recalls through the NHTSA database and report any incidents to help maintain safety standards.

Common Pitfalls: Mistakes to Avoid
- Assuming all cables fit all models: Even small differences in cable length or end fitting design can affect safety.
- Ignoring load ratings: Using a cable with an unknown or lower rating than OEM is a safety risk.
- Installing only one cable: Always replace in pairs to avoid uneven loading.
- Skipping inspection of mounting points: Rust or deformation can compromise even new cables.
- Buying solely on price: Ultra-cheap cables may use inferior materials or fail prematurely.
Upgrades and Alternatives: When Aftermarket Makes Sense
While OEM is the default for most drivers, certain aftermarket options offer genuine upgrades:
- Heavy-duty cables: For work trucks or off-road use, some aftermarket cables feature thicker wire rope, enhanced coatings, or reinforced end fittings.
- Custom lengths or finishes: If you have a modified tailgate or require a specific look, aftermarket suppliers may offer custom solutions.
- Improved corrosion resistance: Some premium cables offer marine-grade stainless steel or advanced polymer coatings for extreme environments.
Always weigh the benefits against the need for proper fitment and certified load ratings.
