A family business since 2013
We started Kozak Parts because we saw how the aftermarket truck parts market worked. Slow shipping, unclear stock, parts that didn't match what was promised. We figured there was room for a company that just does the basics well: keep inventory on hand, check quality before shipping, and answer the phone when someone calls.
Twelve years later, that's still the idea. No big secret, no revolutionary approach — just consistent, reliable work.
We stock what we sell
Most of what you see on the site is sitting in our Seattle warehouse right now. Over 4,500 SKUs — bumpers, hoods, grilles, headlights, mirrors, fenders, and more for Freightliner, Kenworth, Peterbilt, Volvo, and International. We don't drop-ship and we try hard not to list parts we don't actually have. Occasionally something sells out faster than we restock it — but that's the exception, not the norm. When you order, someone here picks it, inspects it, and hands it to the carrier.
Every part passes through our in-house quality check before it leaves the building. We compare dimensions, check fitment, inspect finish. It costs us more time. It saves you returns, downtime, and headaches. That tradeoff is not complicated.
Orders placed by 2:00 PM Pacific usually ship the same day. Not "processing," not "in queue" — actually picked, packed, and handed off. You'll get a tracking number in your inbox.
Owner-operators. Fleets. Body shops.
A truck sitting in a shop isn't earning. We hear that from customers all the time — usually on their first call. Whether you're an owner-operator replacing a damaged mirror or a fleet manager sourcing parts for dozens of rigs, the math is the same: the sooner the right part shows up, the sooner things get back to normal.
That's why we stock deep, ship fast, and pick up the phone when you call. Our support team doesn't read from scripts — they know trucks, they know parts, and they'll help you find the right fitment before you order, not after.
Aftermarket price. Solid fit.
We aim for every part to meet or exceed the manufacturer's specs. That's the bar we use when choosing suppliers — if a part doesn't bolt on cleanly and look right, we'd rather not carry it. Simple as that.
We also offer bulk pricing for shops and fleets. The more you order, the better your cost per unit. No complicated tier systems — call us, tell us what you need, and we'll quote it straight.
