SPTStandard Parts Toolkit
Install on Shopify

Fitment search

A fitment search shoppers actually finish.

Year, Make, Model — plus Sub-Model, Engine, Part Type, and the other qualifiers your catalog needs. Configurable order, configurable styling, a persistent multi-vehicle garage, and result sorting that surfaces in-stock and priority-vendor parts first. Built to be fast on storefronts with up to hundreds of thousands of SKUs.

    Install on category pages, the home page, or any block your theme supports.

What you can configure

  • Year-Make-Model dropdowns - the standard, in a predictable, configurable order, with optional Part Type, Category and Engine qualifiers.
  • VIN Lookup - shoppers paste a VIN and we resolve it to the right vehicle (available today with ShowMeTheParts data source).
  • License-plate lookup - even faster, where the underlying data source supports plate-to-vehicle resolution (available today with ShowMeTheParts data source).
  • My Garage - shoppers save multiple vehicles and switch between them; the selection persists across visits.
  • Catalog search - an alternate, non-fitment search tab for stores that want category browsing alongside YMM.
  • Result sorting - surface in-stock parts, preferred vendors, or specific warehouse locations first
  • In-selector shopping - show pricing and let shoppers add parts to cart directly from the results
  • Custom category - labels and ordering for the part-type lists
  • Layout - inline or modal trigger, with an optional sticky bar; styling driven by your theme tokens
  • Result behavior - filter the current collection or redirect to a fitment-aware results page
  • "No fit" handling - label products that don't match the selected vehicle

Frequently asked questions

How fast is it on a large catalog?
Vehicle dropdowns and fitment lookups are served from indexed data so they stay fast on storefronts with hundreds of thousands of SKUs.
Can shoppers save more than one vehicle?
Yes. The selector includes a "My Garage" that saves multiple vehicles and lets shoppers switch between them, with the selection persisting across visits.
Can I control which parts show up first?
Yes. Results can be sorted to surface in-stock parts and/or preferred vendors so the most relevant options lead.
Can shoppers buy without leaving the search?
Yes. The selector can show pricing and an add-to-cart action on results, so a shopper can add a fitting part to the cart directly from the search.
Does it work with my existing theme?
The toolkit works with Shopify 2.0 compliant themes. Reach out to our team to confirm compatbility.
What happens when a shopper picks a vehicle and lands on a product that doesn't fit?
The product page shows a clear fitment status, and you can configure non-matching products to be hidden, dimmed with a warning, or labeled.
Does it support VIN decoding?
Yes — VIN and license-plate decoding are available today through ShowMeTheParts. Availability for other sources depends on whether the source provides VIN-to-vehicle resolution.
