Track and Wheelbase API: Get Vehicle Fitment Data by VIN
Fitment depends on three numbers: front track, rear track, and wheelbase. The Track & Wheelbase API provides all of these measurements by VIN or year, make, and model. Retrieve vehicle dimensions instantly through an API request.

How the Track & Wheelbase API Works
Retrieve vehicle dimensions through a simple three-step process.
Step 1: Send a GET Request
Send a GET request to the API endpoint with a 17-character VIN or year, make, and model.
Step 2: Receive the Dimensions
The API identifies the vehicle and returns the available front track width, rear track width, and wheelbase.
Step 3: Use the JSON Response
The returned JSON includes the available vehicle and dimensional data for use wherever the information is needed.
What Is a Track & Wheelbase API?

From Database to JSON: Access Access the API YOUR Way
The same track & wheelbase data can be accessed in different ways depending on the intended use.
Vehicle Databases
Direct API Request
Existing Systems
Stop Searching Through Dimension Charts
Finding vehicle dimensions manually can mean searching manufacturer specifications, vehicle catalogs, PDF documents, or multiple online databases. That process becomes difficult to maintain with a large fleet.
Track and Wheelbase API vs. Manual Lookup
| Track & Wheelbase API | Manual Lookup | |
|---|---|---|
| Lookup Method | VIN or year, make, and model request | Manual vehicle search |
| Data Retrieval | Returned automatically | Found manually |
| Response Format | JSON | Different formats and sources |
| Speed | Results instantly | Takes longer per vehicle |
| Automation | Fully automatable | Limited automation |
| Integration | Connects directly to software | Requires manual processes |
| Scalability | Designed for repeated lookups | Difficult at high volume |
| Consistency | Standard response structure | Varies by source |
Send the vehicle details. Get the dimensions. Put the data to work.

FAQs About the Track & Wheelbase API
What is the Track and Wheelbase API?
The Track and Wheelbase API provides front track width, rear track width, and wheelbase measurements for supported vehicles. It can be called using a VIN or year, make, and model.
Can I look up track width by VIN?
Yes. You can submit a 17-character VIN to retrieve the available front and rear track width measurements along with the vehicle’s other returned information.
Can I search by Year, Make, and Model?
Yes. The API supports year, make, and model lookup in situations where a VIN is unavailable or broader vehicle searches are needed.
What measurements does the API return?
The API returns:
- Front track width
- Rear track width
- Wheelbase
The measurements in the example response are provided in inches.
What vehicle years are supported?
The API supports vehicles from 1981 through 2027 across supported US and Canadian coverage.
Does the API return vehicle trim information?
Yes. The response can include the vehicle’s year, make, model, and trim along with the dimensional data.
Can I use this API for vehicle fitment?
Yes. Track width and wheelbase can be used as part of broader vehicle fitment and dimensional workflows. For more complete wheel and tire fitment information, you can combine it with the Tire & Wheel Specifications API.
Can I use the API for high-volume applications?
Yes. The API is designed for integration into automotive applications and automated workflows. Your specific usage limits depend on your API plan and rate limits.
How do I integrate the Track & Wheelbase API?
Send an authenticated GET request using a supported VIN or year, make, and model input. The API returns the available vehicle and dimensional information as JSON.
Can I use the data without integrating the API?
Yes. You can access available vehicle data directly through your Vehicle Databases account if you don’t need to build an API integration.
