How to Buy Trailer Landing Gear Parts: Focus on Quality, Customization, and Durability
Recognizing Quality in Landing Gear Parts
High-quality landing gear parts ensure safety, smooth operation, and reduced long-term costs. Signs of well-made products include:
- Certified Load Ratings: Look for components that meet or exceed industry standards, such as TTMA or AAR certifications. Load ratings (e.g., 50,000 or 66,000 lbs) should match or surpass your trailer requirements.
- Precision Fabrication: Key pieces like legs, sand shoes, and brackets should have high-strength steel, clean welds, and robust mounting patterns. Permanent lubrication in gearboxes is a mark of thoughtful engineering.
- Corrosion Resistance: Components that are galvanized, powder coated, or anodized offer superior protection against rust, especially for trailers exposed to harsh weather or road salt.
- Warranty Coverage: Trusted manufacturers typically back their parts with multi-year warranties. Review warranty terms for coverage on structural failures or gearbox defects.
Customization Options to Consider
No trailer or fleet is exactly alike. Modern landing gear systems and parts often offer customization to meet unique operational needs:
- Mounting Style: Choose among various mounting options: universal, bolt-on, weld-on, or manufacturer-specific patterns. Standard 8-bolt patterns offer the widest interchangeability.
- Gearbox Type: Select between single-speed (simpler, lower cost) or two-speed gearboxes for easier cranking under load and faster operation when unloaded.
- Handle Length and Style: Ergonomics matter; crank handles come in various lengths and folding mechanisms (horizontal or vertical), optimizing fit for trailer geometry and operator comfort.
- Sand Shoe Size & Style: Standard vs. low profile, removable vs. fixed, and cushioned feet are all available. Choose based on the type of terrain your trailer frequently encounters.
- Brace and Strut Configurations: Adjustable braces accommodate different chassis widths and mounting points, while reinforced end sections improve durability under stress.
Durability: What Matters Most
Frequent decoupling, heavy loads, and exposure to the elements make durability essential:
- Internal vs. External Gearboxes: Internal gearboxes are generally better protected from damage and moisture, reducing long-term wear compared to exposed external gears.
- Material Selection: Favor forged or high-strength steel for legs, shoes, and key load-bearing parts. Look for thick-walled tubes and robust cross shafts.
- Low Maintenance Features: Permanent lubrication, floating nut grease reservoirs, and durable bushings extend the service life and reduce required routine maintenance.
- Quality Hardware: Ensure all bolts, pins, and fasteners are made from corrosion-resistant materials.
Practical Tips for Choosing and Using Trailer Landing Gear Parts
-
Identify Your Current Equipment
-
Retrieve the manufacturer and model number from the landing gear leg ID plate.
-
If missing or illegible, record key measurements (mounting pattern, tube size) and take clear photos.
-
Match Parts to Manufacturer and Series
-
Landing gear parts are rarely universal. Specific kits and components are designed to fit certain brands and models (e.g., Holland 50000, JOST A400).
-
Cross-reference model numbers when shopping for rebuild kits or replacement legs.
-
Assess Your Load and Usage Needs
-
Trailers hauling heavy loads or used off-road will benefit from heavy-duty or reinforced components.
-
Choose sand shoe size and type based on typical operating surfaces (soft, paved, gravel).
-
Plan for Future Repairs
-
If one leg or gear has worn out, examine the other components for similar wear.
-
Opt for rebuild kits that replace both gears and bushings for a more comprehensive repair.
-
Invest in Preventive Maintenance
-
Regularly inspect gear mechanisms, welds, and sand shoes for cracks, excessive wear, or corrosion.
-
Maintain lubrication points and tighten any loose hardware.
-
Consider Upgrades
-
Modern landing gear parts offer enhancements like ultralight materials, improved gearboxes, and superior coatings. Upgrading older systems may be more economical in the long run than frequent repairs.
-
Installation Best Practices
-
Always follow manufacturer torque specs and installation instructions.
- If welding is required, use certified technicians to preserve integrity and safety standards.

FAQ
What are trailer landing gear parts?
Trailer landing gear parts are the components—including legs, gearboxes, cranks, braces, and sand shoes—that support and stabilize the front of a trailer when uncoupled from a towing vehicle.
How do I identify the correct replacement part for my landing gear?
Find the manufacturer and model number from the ID plate on your landing gear. If not present, take measurements and photos to match with replacement parts; consult product guides for compatibility.
Are landing gear parts universal?
No. Landing gear parts are typically specific to a manufacturer and model. Using the wrong part can cause improper fit, malfunction, or safety hazards.
What are the signs that my landing gear needs repair or replacement?
Common signs include difficulty raising or lowering the trailer, grinding noises, visible damage or rust, and “skipping” gear action, indicating worn or broken gears.
What is the difference between single-speed and two-speed gearboxes in landing gear?
Single-speed gearboxes offer basic operation, while two-speed gearboxes allow for faster cranking when the leg is unloaded and easier cranking under heavy load.
What are sand shoes, and how do I choose the right one?
Sand shoes are footpads at the base of landing gear legs that distribute weight and prevent sinking into soft surfaces. Select based on size, terrain type, and removability.
Can I rebuild my landing gear or should I replace it entirely?
Many landing gear wear issues can be fixed with rebuild kits targeting the gearbox and bushings, saving time and money. Replace the full assembly if legs are bent, cracked, or severely corroded.
What materials should quality landing gear parts be made from?
Look for high-strength steel with corrosion-resistant coatings (powder coat, galvanized, or anodized) for maximum durability and longevity.
How often should I inspect and maintain my landing gear?
Inspect landing gear for wear, damage, and lubrication at least every three months or per the manufacturer’s maintenance schedule—more frequently for trailers in heavy use or harsh environments.
Can I upgrade my existing landing gear to newer or heavier-duty parts?
Yes, as long as the new parts are compatible with your trailer’s mounting pattern and specifications. Upgrades can include higher-capacity legs, improved gearboxes, or corrosion-resistant finishes. Always verify fit and requirements before purchasing.
