Chassis documentation
Chassis is a Shopify theme for online stores that sell auto and motorcycle parts, accessories and care products. It helps a shopper find the right part for a specific vehicle, and it shows part numbers, specifications and fitment notes clearly on every product. Use this documentation to install the theme, set up your store, and load your vehicle data.
The theme works on its own. You do not need to install an app to use the vehicle selector, the fit check on product cards and product pages, the part number search, the specification tables or the cart. Two features need Shopify's own apps or plans: filtered collection pages (Search & Discovery, free) and volume pricing or stock by location (B2B catalogs and local pickup, which depend on your Shopify plan).
What works without an app
- The vehicle selector, saved garage and current vehicle, in the header and on the home page.
- Fit checks on product cards, product pages and cart lines: "Fits", "Check", "Does not fit" and "Universal part".
- Vehicle pages and the vehicle directory.
- Part numbers: the variant SKU and barcode are shown on cards and product pages and are searched by the store search.
- OEM and cross-reference numbers, fitment notes and specification tables, all from product metafields.
- Quick order by part number, product compare, and bulk add in list view.
- Fitted together (related parts), downloadable fitting guides, and parts diagrams with hotspots.
