Shoppers pick their vehicle.
Your store shows what fits.

It adds a Year / Make / Model vehicle selector to your storefront. A shopper picks their vehicle — say, 2026 Ford Mustang — and your store shows only the products you've confirmed fit it. Fewer wrong-part returns, more confident buyers.

The selector cascades: picking a Year narrows the Makes, a Make narrows the Models, with optional Submodel and Engine for precise fitment. Their vehicle is remembered as they browse, and on product pages the variant picker narrows to compatible options only.

Two ways: add vehicles by hand and assign products with a couple of clicks, or bulk-import a CSV. One flat file does everything — each row creates a vehicle and maps a product to it in the same pass, with a row-by-row validation report when it finishes.

Six columns: Year, Make, Model, Submodel, Engine, Product SKU. Submodel and Engine are optional. Put UNIVERSAL in the Year column to mark a product universal-fit. Export your data any time in the same format — that's also your backup.

A flag for products that fit every vehicle — floor mats, tools, cleaning supplies. Universal Fit items always show, no matter what vehicle the shopper selects, so you never have to map them against thousands of vehicles.

Plans are based on how many vehicle entries you keep — not SKUs, not products, not traffic. Free up to 5,000 entries, Growth ($50/mo) to 20,000, Pro ($100/mo) unlimited. Billing runs through Shopify, on your normal Shopify invoice.

You get a 7-day grace period with notices in the app. If you're still over after that, the storefront selector pauses — your data is never deleted — and it reactivates the moment you upgrade or trim entries.

On any Online Store 2.0 theme, it's a one-click app block in the theme editor — no code. Older themes get a small copy-paste snippet, with instructions built into the app. On large catalogs the selector renders its own results grid, so filtering stays instant even with tens of thousands of products.

No. The widget is a single ~9KB script with no dependencies, and fitment lookups are served from a cache. If our service is ever unreachable, the selector simply hides itself and your store shows all products — it never breaks your storefront.

Per-variant. One part often fits many vehicles, and one product's variants often fit different vehicles — Spark Fitment models both, and product pages narrow the variant picker to what actually fits.

Your fitment data is kept, encrypted, for 90 days after uninstall — so an accidental uninstall or a return from another platform doesn't cost you your catalog work. After 90 days it's permanently deleted.
