What are additional fitment selectors?
Beyond the basic Make/Model/Year/Submodel hierarchy, X-Cart supports additional fitment selectors that let customers further refine their search. These selectors appear on category pages after a customer has selected their vehicle.
Additional fitment selectors are built on vehicle configuration attributes imported from auto integrations. They act as extra filters that narrow down the product list based on vehicle-specific details.
Available selector types
Additional selectors fall into two groups: individual attributes and compound attributes.
Individual attributes
Selector | Description | Example Values |
Drive Type | Drivetrain configuration | FWD, RWD, AWD, 4WD |
Engine | Engine specification | 2.0L 4-Cyl, 3.5L V6, 5.7L V8 |
Transmission | Transmission type | Automatic, Manual, CVT |
Wheelbase | Wheelbase length | Short, Standard, Long |
Brake System | Brake configuration | Disc/Disc, Disc/Drum |
Steering | Steering system | Power, Manual |
Spring Type | Suspension spring | Coil, Leaf |
Compound (Composite) attributes
Some attributes are imported as compound values that combine two related specs into a single filter. This ensures only valid combinations appear (e.g., you won't see "4-door" with "Standard Cab" since that combination doesn't exist).
Compound Attribute | Components | Example Values |
Body Type & Number of Doors | Body Type + Door Count | "Crew Cab Pickup, 4" / "Extended Cab Pickup, 4" / "Standard Cab Pickup, 2" |
Bed Type & Length [inch] | Bed Type + Bed Length (inches) | "Fleetside, 97.6" / "Styleside, 78.9" |
Bed Type & Length [cm] | Bed Type + Bed Length (metric) | "Fleetside, 247.9" |
Note on body type synonyms: Different manufacturers use different names for the same body styles. X-Cart recognizes these equivalences:
Crew Cab = Super Crew
Extended Cab = Super Cab = King Cab = Access Cab
Standard Cab = Regular Cab
Compound attributes are created during import from SEMA Data API or CatalogRack ACES files. If either component of a compound attribute is missing in the source data, the compound attribute is not created.
How additional selectors work
Data Source: Configuration attributes are imported from auto integrations (AutoSync, SEMA Data, ATD) when vehicles are pulled into your store. These attributes are stored as product-class-specific attributes (not global), grouped under "Fitment Details".
Featured Filter Setting: In the X-Cart admin under Cloud Search & Filters, each filter attribute has a "Featured filter" setting with the following options:
Not set — Filter is not featured (appears in normal filter list)
Refine Your Search — Appears in the "Refine Your Search" block
Refine Your Fitment — Appears in the "Refine Your Fitment" block (always expanded)
Select Your Wheel Size — Appears in the wheel size selection block (for wheel/tire stores)
Select Your Tire Size — Appears in the tire size selection block (for wheel/tire stores)
Filter Display Modes: Each filter can be configured with one of these display modes:
Radio Buttons — Select one value (recommended for "Refine Your Fitment" block)
Checkboxes — Select multiple values
Drop-down List — Select one value from a dropdown
Customer Experience
Customer selects vehicle (Make → Model → Year → Submodel)
The "Refine Your Fitment" block appears with additional selectors (always expanded)
Customer picks Body = "Crew Cab Pickup, 4", Drive Type = "4WD"
Product list narrows to show only compatible parts
These selectors do NOT force user selection — customers can skip them and shop freely
Setting up additional selectors
Import vehicle configurations
Ensure your auto integration imports configuration attributes. AutoSync does this automatically; SEMA Data imports compound attributes via ACES files (SEMA Data API and CatalogRack ACES).
Configure Cloud Search & Filters
Go to Store Setup → Cloud Search & Filters. For each attribute you want to promote, set the Featured filter value (e.g., "Refine Your Fitment").
Choose display mode
For each featured filter, select Radio Buttons, Checkboxes, or Drop-down List.
Assign to categories
Optionally limit certain selectors to specific product categories (e.g., show "Bed Type & Length" only in the Truck Accessories category).
Note: This feature is available only for X-Cart Auto stores (stores with automotive add-ons enabled).
