Western Star Semi Truck Parts

Western Star truck parts: body parts & accessories for your rig

We've been in the semi-truck parts business since 2013, and one thing we know for certain - Western Star owners don't settle for second best. These trucks are built heavy, spec'd hard, and run in conditions that would take out anything lighter. The fleet managers, owner-operators, and body shops who rely on us expect the same toughness from their parts supplier. That's exactly what we deliver at kozakparts.com - body parts for Class 8 trucks, in stock, shipping within 24 hours from our warehouse in SeaTac, WA.

We carry western star truck parts for the 4800, 4900, 5700XE, and 6900 series - the models that show up on job sites, long-haul routes, and vocational applications across North America. 

What we stock for Western Star trucks

Here's what you'll find in our Western Star catalog:

• Bumpers – stainless steel 
• Headlights & lighting assemblies - driver and passenger side units
• Grille guards & deer guards - steel guards for vocational and highway applications where wildlife strikes are a real concern

We keep things organized by model so you're not digging through a generic catalog trying to figure out if something fits. Select your Western Star model and year, and you see what's available for your specific truck.

Why buying Western Star parts online makes sense

Western star truck parts online shopping with us means you know exactly what's in stock before you place the order. Price is visible, fitment is spelled out, and shipping is calculated upfront. Orders placed by 2 PM Pacific ship the same day. Most customers across the lower 48 states receive parts within a few business days - we ship out of SeaTac, WA, which puts us in a solid position for coverage across the West Coast, Mountain states, and the Midwest.

For customers who've been searching for western star truck parts near me - and coming up empty because local inventory for these trucks tends to be thin - buying online is genuinely the better option. You get more selection, faster availability, and competitive pricing without being held hostage by whatever happens to be on a dealer's shelf.

We also work with fleet operations regularly. If you're managing multiple trucks and need volume pricing on body parts, reach out directly. We offer bulk discounts and have worked with fleet managers across trucking, construction, and specialty hauling.

Western Star models we cover

Not every parts supplier breaks down their inventory by specific model, which makes it frustrating when you're trying to find western star truck parts for sale that actually fit. We list parts by model series, so here's where we stand:

• Western Star 4900 - this is the model we carry the most inventory for, and for good reason. The 4900 is one of the most widely operated Western Star trucks in the US market. 
• Western Star 4800 - vocational-spec truck, used heavily in construction and municipal applications. 
• Western Star 5700XE parts - the aerodynamic long-haul model. 
• Western Star 6900 - heavy vocational platform. 
• Western Star Accessories - more than just replacement parts

Beyond collision repair and standard replacement parts, we also carry western star truck accessories that drivers and owner-operators use to customize and protect their rigs. Chrome accents, grille guards for highway deer strike protection, and other appearance and protective additions round out the catalog. If you're looking for something specific that isn't showing in the catalog yet, contact us directly.
