Stocking 17 different differential models does not help when none fits the vehicle in your workshop. A slightly different mounting pattern or shaft diameter can turn a simple replacement into hours of modification.
The Avetlink AK replacement differential uses adjustable mounting and interchangeable shaft options to simplify repairs and reduce the number of configurations a shop needs to stock.
The supplied description reports compatibility with more than 90% of electric tricycles within its stated application range, with replacement time reduced from three hours to about 30 minutes. Actual fit must be checked against the vehicle’s complete specifications.

The source also describes a compatible controller and wiring package:
- 48V / 60V / 72V automatic voltage detection, provided by the matched controller.
- Pre-terminated, labeled connections for the throttle, brake, motor phases, and Hall sensors.
These electrical functions belong to the controller and wiring package, rather than the mechanical differential itself.
Practical Benefits for Repair Shops
- Simpler inventory: Adjustable mounting and shaft options can reduce the need for many separate replacement models.
- Less modification work: Matching dimensions can reduce bracket fabrication and other installation changes.
- Easier training: Compatibility charts, clear wiring labels, and installation videos can help standardize the repair process.
- Matched upgrades: A suitable controller can be selected alongside the differential when the vehicle requires an electrical upgrade.
Avetlink AK Wholesale Orders and Service Information
For distributors and repair shops, choosing the right differential helps simplify purchasing and reduce installation problems.
Contact Avetlink to discuss your AK product requirements. Confirm the following details before placing an order:
| Item | Details to Confirm |
| Wholesale orders | Minimum order quantity, product configurations, and delivery schedule |
| Volume pricing | Pricing based on order quantity and selected configurations |
| Custom branding | Logo marking, branded packaging, and customization requirements |
| Installation materials | Available drawings, fitment guides, and installation videos |

| Warranty | Coverage, warranty period, and the process for handling claims |
| Inventory support | Stock planning, replenishment options, and whether consignment arrangements are available |
| Technical support | Contact channels, availability, and expected response times |
A clear record of vehicle compatibility can help repair shops avoid unnecessary stock and select replacement parts more efficiently.
Organize AK configurations by confirmed mounting dimensions, shaft connections, gearing, and motor requirements. This makes it easier to identify suitable parts for vehicles your shop regularly services.
Checking compatibility before ordering also helps reduce installation changes and returns caused by incorrect fit.
Check the Complete Drivetrain
A differential must match both the vehicle’s mechanical layout and its operating requirements. Voltage and motor power alone do not confirm compatibility.
Review the mounting pattern, shaft dimensions, gear ratio, motor torque and speed, available space, and expected vehicle load. If a controller replacement is also needed, check its compatibility with the motor separately.
Frequently Asked Questions
Q1: How can I check whether an AK differential fits my vehicle?
For applications using 48V, 60V, or 72V systems with 500W–1,500W motors, send Avetlink:
- Motor specifications and a clear photograph of the motor label.
- Mounting dimensions and available installation space.
- Shaft diameter and connection type.
- Existing gear ratio, if known.
- Photographs and measurements of the current differential.
These details help determine whether a suitable AK configuration is available. Confirm fitment before ordering.
Q2: What if the vehicle has an unknown controller?
Provide photographs of the controller label, connectors, and wiring, along with the motor specifications.
Check whether the motor uses Hall sensors or sensorless operation, and confirm the required voltage, current, and connections. Discuss identification assistance and suitable replacement options with Avetlink before changing the controller.
Q3: How do I request wholesale pricing?
A: Send Avetlink your required configurations, order quantity, delivery destination, and any branding requirements.
Request a quotation that confirms pricing, minimum order quantity, delivery terms, warranty coverage, and any applicable dealer support.
