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 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 Enhanced 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.
