About Us
Built by a manufacturer, driven since 2012
Tetron Auto Parts has been keeping vehicles on the road since 2012 — and we’re not just a reseller. We’re a manufacturer. We design and produce our BOXI line of aftermarket automotive parts and sell them directly to the people who install them, which means you get factory-direct quality and pricing without the layers of markup that come with a long supply chain.
What we make
Our catalog spans more than 9,000 parts across the systems that matter most for repair and maintenance: suspension and steering — control arms, ball joints, tie rod ends, sway bar links — along with brakes, lift supports and gas struts, wiper transmission linkages, door handles, and much more. Every part is engineered to meet or exceed OEM specifications and cross-referenced to the original equipment and interchange numbers, so you can match it to what came off your vehicle with confidence.
Why buy direct from the manufacturer
Because we manufacture what we sell, we control quality from the ground up and pass the savings straight to you. No distributor markup, no guessing where a part came from — just components we engineer, build, and stand behind, shipped from our own warehouse.
Fitment comes first
The most expensive part is the one that doesn’t fit. That’s why every listing is built around fitment: use our Year / Make / Model search to confirm compatibility before you buy, and review the full specifications and interchange numbers on each product page. If you’re ever unsure, reach out — we’d rather help you get it right the first time.
Quality and warranty
Every BOXI part is manufactured to strict tolerances and backed by a warranty, with the exact terms listed on each product page. We build our parts to perform like the original equipment — and often to outlast it.
Fast shipping to all 50 states
We hold our inventory in-house and ship from our warehouse in Montclair, California, to customers in all 50 states. Because we stock our own parts, orders move quickly and you always know exactly where they’re coming from.
Wholesale & trade accounts
Run a repair shop, garage, or parts business? As the manufacturer, we’re set up to supply you directly. We offer wholesale pricing and dedicated trade accounts for business customers — get in touch to open an account and access B2B pricing on the parts you order most.
