Shopify is a leading platform for online stores, especially those in the auto sector—and finding the right Shopify fitment apps that cater to year, make, and model data is vital for businesses that want to streamline their operations.

These apps not only simplify the inventory process for auto parts suppliers, but also ensure compatibility for buyers, which can help reduce returns and increase sales. But with so many options available in the Shopify App Store, choosing the best fit can be daunting.

In this guide, we compare the top Shopify apps for managing year/make/model (YMM) fitment data—covering pricing, ratings, ease of import, customization options, and who each app is best for.

What Is Fitment Data?

Fitment data refers to detailed information regarding the year, make, and model (YMM) of a vehicle. This data can extend to include specifics about a vehicle’s submodel, trim, or engine specifications.

Essentially, it helps shoppers confirm compatibility between a product and a vehicle, ensuring that the parts or accessories they buy will fit as intended. In the aftermarket industry, fitment data is often exchanged in standardized formats like ACES and PIES (more on those in the FAQ below).

Adding this data to your Shopify website will give you significant advantages, including:

  • A better shopper experience.
  • Fewer returns.
  • Better inventory management.
  • A boost in sales.

Our Reviews of the 8 Best Fitment Apps for the Shopify Platform

Let's face it: the task of manually uploading a new listing for each year, make, and model on Shopify is almost impossible.

Luckily, there are solutions available.

Shopify fitment apps streamline this process by providing fitment integrations, along with features for importing and exporting data. Plus, most of them are incredibly easy to use—simply visit Shopify, then log in to install.

Here are eight of our favorite Shopify fitment apps, their features, and pros and cons: 

How we evaluated these apps: We re-verified every app against its live Shopify App Store listing (pricing, ratings, and feature claims), compared data-import options (CSV, API, ACES), weighed monthly cost against catalog-size limits, and read recent merchant reviews for support quality. We build a fitment app ourselves, so where we’re biased, we say so.

1. ConverMax — best for large catalogs and advanced fitment search

Convermax

Convermax is compatible with over 15 fitment data resources, ensuring that your customers always find parts that fit their vehicles.

This tool is designed to take the hassle out of managing your store's inventory and fitment data, allowing you to concentrate on what matters most—growing your business.

With Convermax, your website can gain access to a suite of advanced search functionalities, including YMM search, wheels and tires search, VIN search, and the ability to filter by keywords. Its newer releases add hybrid semantic search with AI re-ranking, plus a “My Garage” feature so returning customers can shop for their saved vehicles.

One of its standout features is its capability to work with fitment data in any format. Whether you're dealing with data from APIs, spreadsheets, or ACES files, Convermax's search engine can effortlessly pull and compile data from various sources.

Convermax holds a 5.0-star rating on the Shopify App Store. Pricing starts at $250 per month (up to 50,000 monthly visitors) and goes up to $850 per month, with a 30-day free trial and no setup fees.

Pros and cons of ConverMax:

Pros

Cons

2. Spark Fitment — best value year/make/model app

Spark Fitment year/make/model vehicle selector for Shopify

Spark Fitment is a Shopify year/make/model app built by our team here at Spark Shipping—so yes, we’re biased, but we built it because so many auto parts sellers told us existing options were either too limited or too expensive. The pitch is simple: “Shoppers pick their vehicle. Your store shows what fits.”

Shoppers use a cascading Year → Make → Model (with optional Submodel/Engine) selector, and the storefront filters down to confirmed fits only. Their vehicle selection persists as they browse, so every collection and search stays filtered to their car.

Where Spark Fitment stands out is the data model: fitment can be mapped per variant, not just per product—essential when one listing covers multiple part configurations. Bulk CSV import validates row by row, a Universal Fit flag handles products that fit every vehicle, and the storefront widget is a lightweight ~9KB script that installs with one click in any Online Store 2.0 theme. It stays fast on catalogs of 20,000+ products.

Pricing is straightforward: a free plan covers up to 5,000 vehicle entries, the Growth plan is $50 per month for 20,000 entries, and the Pro plan is $100 per month for unlimited entries.

Pros and cons of Spark Fitment:

Pros

Cons

Genuinely free plan (up to 5,000 vehicle entries)—no trial expiration.

Newer to the App Store, so it has a shorter public track record than veterans like EasySearch.

Per-variant fitment mapping, not just per-product.

No preloaded vehicle database—you import your own fitment data via CSV.

Lightweight ~9KB storefront script with one-click Online Store 2.0 theme integration.

 

Pairs natively with Spark Shipping’s vendor automation, so fitment data can flow in from your distributors.

 

3. EasySearch — the most-reviewed YMM app on Shopify

EasySearch

EasySearch (by NexusMedia) is the veteran of this list—it has been on the App Store since 2016 and boasts a 4.9 out of 5 star rating across 147 reviews. It carries Shopify’s “Built for Shopify” badge, works with the latest themes, and you can manage it directly in Shopify admin.

EasySearch’s biggest selling point is its low cost and the fact that it comes preloaded with a database of YMM data. Of course, if you don’t want to use their database, you can always import a CSV of your own. A “My Garage” feature lets returning shoppers save their vehicles, and the Premium tier adds fitment tables on product pages and universal product linking.

If you aren’t ready to commit, it offers a free 14-day trial. The Basic plan is $19 per month, with a Premium plan at $75 per month—a powerful, affordable fitment app that can streamline your store’s performance with a few clicks.

Pros and cons of EasySearch:

Pros

Cons

Overwhelmingly positive reviews: 4.9 out of 5 stars across 147 reviews, plus the “Built for Shopify” badge.

Some store owners using the app experienced complications when searching for all products related to a specific vehicle.

A free trial and $19 per month entry plan make it affordable, even for small businesses.

Fitment tables and universal product linking require the $75 per month Premium plan.

Comes preloaded with a YMM database, with flexibility to import your own via CSV.

Pros and cons of C: Year Make Model Search:

Pros

AutoFit AI ‑ Year Make Model (by Cartmade) is the newest app on this list, launched in late 2025—and it takes a distinctly modern approach to fitment.

Alongside the standard YMM dropdowns, AutoFit AI adds VIN and registration (VRN) lookup, so shoppers can identify their exact vehicle without knowing its specs. Fitment compatibility tables appear on product pages, a “My Garage” feature saves customer vehicles, and an AI chat assistant answers fitment questions 24/7.

Pricing runs from $19.99 per month (Starter) up to $149.99 per month (Elite), all with a 14-day free trial and a 20% discount for annual billing.

A word of caution: because it’s so new, AutoFit AI has only a handful of reviews so far (3.6 stars across 3 reviews at the time of writing). It’s worth a trial for the VIN lookup alone—but test it thoroughly before committing.

Pros and cons of AutoFit AI:

Pros

Cons

VIN and registration lookup at a fraction of the price competitors charge for it.

Very new, with a limited review history (3.6 stars across 3 reviews).

AI chat assistant answers customer fitment questions around the clock.

Full feature set requires the pricier Growth, Pro, or Elite tiers.

Fitment compatibility tables, My Garage, and bulk CSV import included.

Shopify Fitment App FAQs

What is fitment data?

Fitment data is the information that describes which vehicles a part or accessory fits—typically the year, make, and model (YMM), and often the submodel, engine, or trim. Online stores use it to let shoppers filter the catalog down to parts confirmed to fit their exact vehicle.

What are ACES and PIES?

ACES (Aftermarket Catalog Exchange Standard) and PIES (Product Information Exchange Standard) are the two data standards used across the North American automotive aftermarket. ACES describes vehicle fitment (which vehicles a part fits), while PIES describes the product itself (attributes, pricing, images). Apps like ConverMax can ingest ACES files directly. For a deeper dive into both standards, read our full ACES and PIES guide.

Does Shopify support year/make/model search natively?

No. Shopify has no built-in concept of vehicle fitment, and its default search and collection filters can’t express “fits a 2019 Ford F-150.” That’s why auto parts stores install a fitment app—each app in this list adds the YMM selector, fitment storage, and filtered browsing on top of Shopify.

How much do Shopify fitment apps cost?

Pricing spans a wide range. Entry-level apps start under $20 per month (VFitz from $0.97, C: Year Make Model Search from $10, EasySearch from $19), Spark Fitment has a free plan up to 5,000 vehicle entries, and enterprise-grade search platforms like ConverMax run $250–$850 per month.

How do fitment apps reduce returns?

Wrong-part orders are one of the biggest sources of returns for auto parts sellers. A fitment app makes the shopper declare their vehicle up front and only shows compatible parts, so mismatched purchases largely never happen. azFitment, for example, claims its merchants cut return rates from 8% to 1.5%.
