THE PROBLEM

Fitment is a nightmare.
And it costs you customers.

86%
of auto parts returns trace back to incorrect fitment — not defective products.
$47B
lost annually in the aftermarket parts industry from wrong-part orders and returns.
20+
attributes needed to confirm a single part's compatibility across truck model years.
3x
more complex than general retail. Most shops have no automation for this.

"I can't tell you how many times a customer ordered a lift kit that fit a completely different trim. We eat the return. They leave angry. Amazon wins."

HOW IT WORKS

The Fitment Engine.

Built for the complexity of custom truck parts. Not a dropdown filter — a reasoning system that understands vehicles, modifications, and compatibility at depth.

01

Natural Language Query

Customers type in their question or describe their truck. No dropdowns, no guessing what trim they have. "Will this bumper fit my 2019 Ram 1500 with the off-road package?"

02

Vehicle Intelligence

Cross-references year, make, model, engine, cab configuration, bed length, drivetrain, and package codes. Handles the quirks that generic fitment tools miss.

03

Verified Compatibility

Every recommendation is verified against your inventory and real fitment data. If it recommends it, it fits. That's the promise.

WHO IT'S FOR

Built for the small guy.
Competing against the big guys.

Truck Parts Retailers

You have 15,000 SKUs and no good way to help customers find what fits their rig. TreadForge turns your catalog into an intelligent conversation.

Off-Road Shops

Your customers drive modified builds with custom configs. Standard fitment tools don't know what a "squatted 2018 Silverado Z71" is. TreadForge does.

Distributors & Wholesalers

Moving inventory fast means helping your B2B customers find the right part every time. TreadForge integrates into your existing system and runs 24/7.

Every wrong part order is a customer you lost forever.

Big box retailers have massive catalogs and dedicated data teams to make fitment work. Small shops don't. They lose customers on guesswork, watch them search Amazon instead, and never get them back. TreadForge exists to close that gap. Not by building a better dropdown. By building an AI that actually understands your parts and your customers' trucks.

We're not here to replace the expertise of a good parts counter. We're here to multiply it.
