Fitment engine
Suspension makers publish fitment in titles, tables and fine-print notes that are kept separately and often disagree. Our fitment engine turns that into verified fitment a shop or a customer can trust: it asks only the questions that matter for the truck in front of you, and shows what else the job needs.
How it works
- Highly structured data. Every kit is stored as structured data on the industry vehicle standard (year, make, model, trim, drive, fuel), with the source of every value.
- Decision rules. Rules decide what fits, which questions to ask, which vehicles are excluded, and which extra parts or work go on the quote. A question the truck already answers is never asked.
- Machine learning. A trained model gives a second opinion on every maker note: does it restrict fit, require a part, depend on the truck, or only give advice?
- AI. AI reads the notes, install instructions and maker websites, and every answer it finds is tied to an exact quote.
- Independent review. Independent reviewers check every part number against the maker's own data. Where a maker's data disagrees with itself, we offer only what both sources agree on, and ask the maker. We never widen fitment on our own.
Results on real maker data
Share of part numbers that passed an independent check against the maker's own data, on the first pass and now.
| Maker | Part numbers | First pass | Now |
|---|---|---|---|
| Maker A, three lift brands | 3,959 | 38% | 89% |
| Brand 1 | 2,621 | 40% | 89% |
| Brand 2 | 886 | 33% | 82% |
| Brand 3 | 452 | 37% | 98% |
| Maker B, one brand | 127 | 26% | 84% |
What it took
| Maker A | Maker B | |
|---|---|---|
| Distinct maker notes read | 1,620 | 213 |
| Open points answered from the maker's own install sheets and websites | 242 | 77 |
| Questions sent to the maker | 279 | 83 |
| …yes/no confirmations quoting the maker's own sources | 198 | 66 |
| …open questions | 81 | 17 |
The remaining part numbers wait on the maker's answers or on fixes on our side. Until then, the engine keeps to the safe side.
Who builds it
Ottotek is built by a team with more than 20 years in the 4x4 and performance industry. Half the team brings two decades of hands-on shop work and business management; the other half brings two decades of software development, with the same passion for automotive performance.
We use what we build in our own shop, every day. Hands-on experience guides every decision we make.
Where it's headed
- Dealers, through our API and web tools: a configurator and a ride-height visualizer.
- Shops, in the Otto shop management system, for quoting, ordering and install time.
- Makers get back real install times and fit issues reported by shops.
