Fitment drives discovery on the way in, and the wrong part doesn't make it into the cart in the first place. Uncap Garage is fitment, built for automotive on Shopify. Shoppers save their vehicle once and see only the parts that fit, while you manage Year/Make/Model fitment for the whole catalog from one place. ## In auto parts, the wrong part isn’t a return. It’s a lost customer. - Shoppers guess whether a part fits, then send it back when it doesn’t. - Fitment lives in spreadsheets that never quite match the storefront. - Search buries the right SKU under a thousand that don’t fit the vehicle. **With Uncap Garage:** - Shoppers pick their vehicle once and only ever see parts that fit. - One fitment record per product, synced live to the storefront. - Year/Make/Model filtering narrows the catalog to the exact match. ## How it works 1. Map: Import ACES/PIES or your own data and map every product to the vehicles it fits. 2. Save: Shoppers build their garage (Year, Make, Model, engine) and keep it across visits. 3. Shop: The whole storefront filters to their vehicle, so every result is a guaranteed fit. ## What's inside - Your Garage: A vehicle selector shoppers save once and reuse everywhere. - YMM filtering: Year/Make/Model narrows catalog, search, and collections. - Guaranteed fit: Fits / doesn’t-fit badges on every product and variant. - ACES/PIES ready: Import industry-standard fitment, or bring your own. - Catalog-wide: One fitment record powers PDP, search, and collections. - Coverage console: See what’s mapped, what’s missing, and close gaps fast.

Uncap Garage is a Year-Make-Model fitment app for Shopify that shows automotive buyers only the parts that fit their vehicle. It is built by Uncap, a Shopify Platinum Partner and Shopify Expert, on Shopify since 2013. Buyers select their year, make, and model, and the storefront filters to the parts that fit, which drives product discovery and prevents wrong-part returns. It is built for automotive parts and accessories merchants running on Shopify. ### How does Year-Make-Model fitment work on a Shopify store? Year-Make-Model (YMM) fitment works by letting a buyer pick their vehicle, then filtering the catalog so they see only the parts that fit it. Uncap Garage adds a YMM selector to the storefront and makes product pages, search, and collections fitment-aware. Buyers can save their vehicles to a garage and return to a store that already knows what fits. This removes the guesswork that leads to ordering the wrong part for the wrong vehicle. ### What are ACES and PIES, and does Uncap Garage use them? ACES (Aftermarket Catalog Exchange Standard) and PIES (Product Information Exchange Standard) are the auto care industry's standards for vehicle fitment data and product information. Uncap Garage is powered by ACES and PIES data, so fitment stays accurate without a merchant maintaining a fitment spreadsheet by hand. The standardized database does the heavy lifting, which keeps the catalog current and the fitment reliable. ### Can fitment software reduce wrong-part returns for auto parts stores? Yes. Fitment software reduces wrong-part returns by stopping the mismatch before checkout, not after. Uncap Garage shows buyers only the parts that fit their selected vehicle and prevents wrong-fitment items from entering the cart, so the return, the refund, and the lost buyer never happen. For automotive merchants, returns from incorrect fitment are a common and costly problem, and catching it at the point of selection is what removes it. ### Who is Uncap Garage for? Uncap Garage is for automotive parts and accessories merchants selling on Shopify who need fitment to drive discovery and cut returns. It fits stores whose buyers shop by vehicle, including aftermarket parts sellers, accessory retailers, and distributors serving the automotive market. It works for businesses that want buyers to find the right part the first time, without a team manually maintaining fitment data.
