Shopify app · vehicle parts fitment
Every part, matched
to the vehicle
in their driveway.
WySync Fitment turns a Shopify parts store into a vehicle-first storefront. Shoppers pick their vehicle once — search, collections, product pages and the cart all answer for that vehicle, every time, until they check out. Wheels, brakes, suspension, lighting, exhaust, protection: if it only fits some vehicles, it belongs behind this.

01The problemWrong-fitment returns
The wrong part is never
just a refund.
A lift kit that doesn't clear, a brake kit for the wrong caliper, a set of four wheels on the wrong bolt pattern. You eat freight both ways on heavy boxes, refund the sale, absorb the restock, and lose the customer to the shop that answered the question before they ordered.
"Will this fit my truck?"
The single most-asked pre-sale question in the aftermarket, on every category you carry — and the one your product page is silent about. Every unanswered one is a chat, an email, or a bounce.
Filters that don't know the vehicle
Native Shopify filters narrow by brand, size and colour. They cannot tell a 2019 Tacoma from a 2019 4Runner, so the shopper still has to work out compatibility themselves — and half of them guess.
Fitment locked in a spreadsheet
Most shops already own the mapping data — in a supplier CSV, a tag scheme, a sheet someone maintains by hand, an ACES export nobody can open. It just never reaches the storefront.
02The journeySix surfaces, one vehicle
The vehicle is picked once and never asked for again.
Each widget reads the same vehicle state. Change it anywhere and the whole store re-answers — including the cart the shopper filled twenty minutes ago.

Order03Who it's forAny vehicle-specific catalog
If it only fits some vehicles,
it belongs behind this.
Fitment is a shape, not a category. A lift kit, a brake caliper, a wiper blade and a set of wheels all fail in the same way — the shopper cannot tell whether it works on their vehicle. WySync answers that identically for all of them.
Wheels & tires
Bolt pattern, offset, hub bore, diameter and load rating — the hardest fitment in the aftermarket, and the one we started with.
Suspension & lift
Lift and lowering kits, coilovers, control arms, leaf packs. Fitment by platform, often by trim and drivetrain.
Brakes & drivetrain
Rotors, pads, big brake kits, axles, differentials. Front/rear position matters as much as the vehicle does.
Lighting & electrical
Bars, pods, fog kits, harnesses, tail lights. Direct-fit SKUs that live or die on the year range.
Engine & exhaust
Intakes, cat-backs, headers, tuners. Fitment is often engine-specific inside one model.
Exterior & protection
Tonneau covers, bull bars, fender flares, floor liners, roof racks, mud flaps.
Towing & utility
Hitches, wiring harnesses, brake controllers, ball mounts.
Service & consumables
Wipers, filters, belts, bulbs — high-volume parts nobody wants to return.
Spec fields are typed, not hard-coded. The index carries whatever attributes your catalog has —
spec_num_*, spec_int_*, spec_str_*, spec_strs_*, spec_bool_* — so blade length, compound, thickness and attachment type work exactly like diameter and offset do. How spec mapping works.04The widget suiteAll nine on every plan
Nine widgets. No à-la-carte pricing.
Every plan ships the complete suite, whatever categories you sell. Plans differ on how many supplier integrations you connect and how fast the index refreshes — never on what your customers get to use.

Selling wheels or tires?
You can rent our data too.
For wheels and tires specifically, the add-on removes the need for a mapping row at all. It matches your product specs against our curated data at query time — 65,000 vehicles, wheel spec envelopes, 1.2 million tire sizes — and returns a tiered verdict, including an honest does not fit when the specs rule it out. Every other category keeps using the sources you connect.

07Under the hoodWhy it's fast
Built like infrastructure, not like an add-on.
Your storefront never waits on Shopify's API for a fitment answer. Products are indexed in the background into a per-shop search index; the storefront only ever talks to that.
Typesense-backed
Every storefront query hits a per-shop search index with a Redis layer in front. Fitment filtering is an index intersection, not a scan.
Isolated per shop
Separate index, separate cache namespace, separate config. Your catalog, queries and mappings are never in a shared table.
Realtime or scheduled
Growth and above subscribe to product, inventory and price webhooks with a daily full reindex as a safety net.
GraphQL-only, no REST
Bulk operations for the full catalog, throttle-aware retries, and jobs that recover themselves after a deploy.
We run an aftermarket storefront ourselves. The engine was built because we needed it on our own catalog first — then rebuilt multi-tenant so other shops could run it, whatever they sell.
