When an aerial lift needs a replacement part, buyers often face the same question:
Should I buy an OEM part or an aftermarket replacement?
There is no single answer that applies to every component or every repair.
OEM and aftermarket parts can differ in price, availability, manufacturing source, warranty, packaging and support. But the most important question is still whether the replacement is correctly specified for the machine and the application.
A cheaper part that does not fit is not good value. An expensive part is not automatically the best choice simply because it comes from the original manufacturer.
This guide explains how to compare OEM and aftermarket aerial lift parts more intelligently before ordering.
What Is an OEM Aerial Lift Part?
OEM stands for Original Equipment Manufacturer.
In the context of aerial lift replacement parts, an OEM part is supplied under the original equipment manufacturer's parts system and identified using the manufacturer's part number and application information.
OEM parts are normally selected using information such as:
- OEM part number
- Machine model
- Machine serial number
- Manufacturer parts documentation
One of the main advantages of an OEM part is that its application is tied directly to the manufacturer's parts system.
However, OEM availability, price and lead time can vary depending on the component and machine age.
What Is an Aftermarket Aerial Lift Part?
An aftermarket part is produced by a supplier other than the original equipment manufacturer and is intended to replace or cross-reference an original part.
Aftermarket parts can include:
- Platform control boxes
- Joysticks
- Control boards
- Switches
- Motors
- Hydraulic pumps
- Hydraulic motors
- Wiring components
- Other service parts
The quality and accuracy of aftermarket parts can vary significantly between suppliers.
For that reason, “aftermarket” should not be treated as one single quality level.
A good aftermarket replacement should be evaluated by its actual compatibility, construction, specifications and supplier support.
Aftermarket Does Not Automatically Mean Lower Quality
A common assumption is that OEM always means high quality and aftermarket always means low quality.
That is too simple.
Aftermarket products can range from poorly documented generic parts to carefully manufactured replacements designed for specific OEM references and machine applications.
The useful questions are:
- Is the part correctly cross-referenced?
- Does the physical configuration match?
- Are the required electrical or hydraulic specifications correct?
- Has the supplier clearly documented the application?
- Is warranty or technical support available?
These questions tell you more than the word “aftermarket” by itself.
Compatibility Should Be the First Comparison
Before comparing price, packaging or delivery time, first establish whether the replacement is actually correct for the machine.
Depending on the component, compatibility may require checking:
- OEM part number
- Machine model
- Machine serial number
- Connector configuration
- Mounting
- Voltage
- Hydraulic ports
- Shaft or coupling
- PCB revision
- Control layout
Not every part uses all of these checks.
The important point is that compatibility should be based on the actual component—not only on the general machine model.
Why OEM Part Numbers Matter for Aftermarket Parts
The OEM part number is often the bridge between the original component and an aftermarket replacement.
A well-documented aftermarket listing should clearly indicate which OEM reference it is intended to replace.
However, a matching number in a product title should still be verified against:
- The actual product configuration
- Machine application
- Serial-number range where relevant
- Visible interfaces
This is especially important when an OEM number has been revised, superseded or used within a particular production range.
See our Aerial Lift Part Number Guide for more information about OEM numbers, revisions and superseded parts.
Compare the Actual Part, Not Just the Listing Title
Product titles are useful for search, but they should not be the only source used to confirm compatibility.
Review the actual product photographs and compare them with the original part.
Depending on the component, look at:
- Connector layout
- Control layout
- Mounting points
- Hydraulic ports
- Shaft or output interface
- Wire harness layout
- Board revision
- Physical dimensions
If an important visible feature does not match, investigate before ordering.
Some Parts Require More Verification Than Others
Not every aerial lift replacement part carries the same compatibility risk.
A simple mechanical component may require relatively few checks.
Electronic or hydraulic components may require much more detailed verification.
Control Boxes
Compare the OEM number, control layout, joystick configuration, connectors and machine application.
Joysticks
Check the connector, mounting, handle configuration, trigger and documented application.
Control Boards / PCBs
Part number, PCB revision, connector layout, machine application and programming requirements can all matter.
DC Motors
Voltage alone is not enough. Shaft, mounting, electrical terminals and actual motor application must also match.
Hydraulic Pumps and Motors
Ports, mounting, shaft or coupling, rotation and hydraulic specifications may all affect compatibility.
OEM vs Aftermarket: Price
Price is one of the most obvious differences buyers compare.
Aftermarket replacement parts are often available at a lower purchase price than an OEM alternative.
But purchase price should be evaluated together with:
- Compatibility confidence
- Product quality
- Availability
- Shipping time
- Warranty
- Potential machine downtime
A lower unit price provides little value if the machine remains out of service because the wrong part was ordered.
Total Repair Value Matters More Than Unit Price
For repair shops, equipment owners and rental fleets, the real cost of a replacement part is not always the number shown on the invoice.
The total repair can also involve:
- Machine downtime
- Technician labor
- Repeated disassembly
- Return shipping
- Reordering delays
- Lost equipment availability
A correctly identified replacement that arrives quickly can sometimes provide better total value even when another option has a lower initial price.
Availability Can Be a Major Advantage
For older machines or less common components, availability can become an important part of the buying decision.
An OEM part may sometimes have:
- Long lead time
- Limited inventory
- Regional availability differences
- Discontinued or superseded status
A correctly specified aftermarket replacement can provide another sourcing option when the original part is difficult to obtain.
Availability alone does not prove compatibility, but it can significantly reduce equipment downtime when the replacement has been properly verified.
What Should You Look for in an Aftermarket Supplier?
The supplier matters almost as much as the part.
Useful signs include:
- Clear OEM cross-reference information
- Real product photographs
- Machine compatibility information
- Part-number support
- Ability to review customer photos
- Clear warranty information
- Accessible technical or customer support
Be cautious when a product listing provides only a generic image and broad claims such as “fits many models” without explaining the actual application.
Real Product Photos Are Important
Real product photography allows the buyer to compare the replacement directly with the original component.
For industrial parts, useful images should show the features that matter for fitment.
Examples include:
- Connectors
- Mounting points
- Shafts
- Hydraulic ports
- Control layouts
- PCB shape and connectors
- Product labels
A single attractive front photo may not provide enough information for technical identification.
How Important Is Warranty?
Warranty terms are another useful comparison point.
A warranty does not prove compatibility or product quality by itself, but it shows what support is available if a product develops a qualifying problem.
Before purchasing, understand:
- Warranty period
- What is covered
- What evidence may be required
- How replacement claims are handled
The supplier's ability to respond after the sale is part of the overall value of the replacement.
Does Aftermarket Mean the Part Must Look Identical?
Not always.
Some functional replacements may have minor cosmetic or manufacturing differences while maintaining the required interfaces and specifications.
However, important compatibility features should not be dismissed as cosmetic.
Differences in:
- Connector type
- Mounting
- Shaft
- Hydraulic ports
- Control layout
- PCB configuration
can indicate that the replacement is not correct.
The key is distinguishing a harmless visual difference from a functional compatibility difference.
When OEM May Be the Better Choice
OEM parts can be the preferred choice when:
- The application requires an OEM-specific component
- No verified aftermarket replacement is available
- Programming or configuration is manufacturer-specific
- The customer or maintenance policy requires OEM parts
- The repair documentation specifies a particular OEM assembly
The correct choice depends on the actual machine and repair requirements.
When a Verified Aftermarket Part Can Make Sense
A quality aftermarket replacement can be a practical option when:
- The OEM reference is clearly established
- The machine application has been verified
- The important interfaces match
- The technical specifications are correct
- The supplier provides clear product information
- Price or availability offers a meaningful advantage
The important word is verified.
Choosing aftermarket should not mean accepting uncertainty about fitment.
Do Not Compare OEM and Aftermarket by Price Alone
A better comparison uses several questions:
Does it fit?
Confirm the actual machine and component application.
Does it match the required specification?
Check the electrical, hydraulic and mechanical requirements that apply to the part.
Is the product clearly documented?
Look for real photos, OEM references and fitment information.
Is it available when the machine needs it?
Lead time can affect total repair cost.
What support is available?
Consider warranty, identification support and after-sales service.
What is the total value?
Compare the complete repair outcome, not just unit price.
What Information Should You Verify Before Ordering Any AWP Replacement Part?
A strong basic identification package includes:
- OEM part number
- Machine manufacturer
- Exact machine model
- Complete serial number
- Clear original-part photos
- Connector or port photos
- Relevant electrical or hydraulic specifications
- Mounting or shaft details where applicable
The exact information depends on the type of part being replaced.
If you are unsure which details matter, send a wider photo of the complete original component before taking only close-up images.
Common OEM vs Aftermarket Buying Mistakes
Assuming Aftermarket Means Universal
An aftermarket replacement should still be matched to a specific OEM reference or machine application.
Buying Only by Lowest Price
Incorrect fitment can create more downtime and expense than the initial savings.
Ignoring the Machine Serial Number
Production changes can affect which version of a component is required.
Trusting the Product Title Without Checking the Photos
The actual product configuration should agree with the original part.
Assuming Same Connector Means Same Part
Connector fit does not prove electrical or functional compatibility.
Assuming Same Voltage Means Same Motor
Motor compatibility can also depend on shaft, mounting, terminals and machine application.
Confusing Individual Components With Complete Assemblies
A motor, pump, joystick, PCB or switch may be sold separately from the larger assembly in which it is installed.
A Practical Replacement-Part Buying Process
1. Identify the original part.
Find the OEM number and photograph the complete component.
2. Identify the machine.
Record the exact model and serial number.
3. Determine the important interfaces.
Connector, ports, shaft, mounting or control layout depending on the part.
4. Compare the replacement.
Use actual product photographs and documented specifications.
5. Confirm the replacement level.
Individual component or complete assembly?
6. Compare availability, warranty and price.
Do this after compatibility has been established.
7. Order with compatibility confidence.
Do not use installation as a test to determine whether the part is correct.
Frequently Asked Questions
Are aftermarket aerial lift parts reliable?
Quality varies by manufacturer and supplier. Evaluate the actual product, compatibility documentation, construction, warranty and supplier support rather than judging all aftermarket parts as one category.
Are aftermarket aerial lift parts always cheaper than OEM?
They are often competitively priced, but pricing varies by component and supplier. Total repair value also includes availability, downtime and compatibility.
Can an aftermarket part replace an OEM part number?
Yes, when the aftermarket part is specifically designed and verified for that OEM reference and machine application.
Does an aftermarket part have to look exactly like the OEM part?
Not necessarily. Minor cosmetic differences may exist, but the important mechanical, electrical or hydraulic interfaces and required specifications must still match.
Should I choose OEM for electronic control boards?
The decision depends on the specific board. PCB revision, connectors, programming and machine application can make electronic components more sensitive to compatibility differences.
What is the most important thing to check before buying aftermarket parts?
Compatibility. Confirm the OEM reference, machine application and the important physical or technical interfaces before comparing price.
Final Thoughts
The OEM-versus-aftermarket decision should not be reduced to “expensive versus cheap.”
The better comparison is:
Compatibility + Product Quality + Availability + Support + Total Value.
OEM parts provide a direct manufacturer parts path. A well-documented aftermarket replacement can offer another practical option when it has been correctly matched to the original component and machine.
For either option, the most important step remains the same:
Identify the part correctly before ordering it.
