Stores that source through Parts Unlimited usually run into the same wall: the fitment information for a part exists somewhere in the distributor relationship, but it is not connected to the Shopify storefront where customers are actually shopping. Without that connection, shoppers are left to guess whether a part fits, or to email and ask.
The gap between distributor data and storefront search
A Parts Unlimited catalog line and a Shopify product listing are two different records for the same item. To power a Year, Make, Model search, something has to match the two together and carry the compatibility information across. Done manually, that means tagging every product with every compatible vehicle, then repeating the work every time your catalog or your supplier's data changes.
Skip that step, and the fallback is ordinary keyword search, which cannot distinguish a compatible part from an incompatible one. That gap shows up as returns, and as support questions that a working fitment tool should be answering on its own.
What automatic fitment integration looks like
Rather than tagging by hand, a distributor-aware fitment app matches your Shopify products to Parts Unlimited catalog data using SKU and brand. Where it finds a match, the product's full compatibility range attaches automatically, both to a Year, Make, Model search widget and to a fitment table on the product page. When the Parts Unlimited catalog updates, the match runs again, so the fitment on your store stays current without anyone maintaining it by hand.
MotoFit matches your Shopify products to the Parts Unlimited catalog by SKU and brand, and attaches fitment automatically. WPS and Turn 14 Distribution are matched the same way, so a catalog sourced from more than one distributor is still covered end to end.
What setup actually involves
- Your Parts Unlimited dealer access, so the fitment data behind your products can be read.
- A quick check that the SKUs and brand names on your Shopify catalog match how Parts Unlimited lists them, since that is what the match runs on.
- A decision on where the search should live: homepage, collection pages, as a popup, or all three.
There is no data migration and no developer needed. Most stores go from connecting their Parts Unlimited feed to a working search in under 10 minutes.
Quick answers
No. Your ordering relationship stays exactly as it is. This only connects their fitment data to your storefront search and product pages.
Only products sourced from a supported distributor sync automatically. MotoFit also covers WPS and Turn 14 Distribution, so a mixed catalog is still handled.
Most stores are live in under 10 minutes once the Parts Unlimited feed is connected. The MotoFit team helps with widget placement and styling if you want it.
