You can buy derby car parts from a mix of specialty online stores, salvage yards, and local racing suppliers. The best source depends on your budget, how quickly you need the part, and whether you're looking for new, used, or heavy-duty aftermarket components. For common replacement parts like body panels or bumpers, local salvage yards are often the most cost-effective choice. For specialized safety equipment or performance upgrades, online retailers that cater specifically to demolition derby or dirt track racing are your best bet.
Specialty Online Retailers Websites like Summit Racing, JEGS, and Speedway Motors are go-to sources for new performance parts, racing seats, harnesses, and drivetrain components. For demolition-derby-specific gear, shops like Varsity Derby Parts and BC Derby Parts offer reinforced parts like welded driveline loops and heavy-duty radiator mounts designed to withstand impacts.
Salvage Yards and Pull-Your-Part Lots This is the heart of derby building. For the uninitiated, a "pull-your-part" yard is a DIY salvage yard where you bring your own tools to remove parts from vehicles. This is ideal for finding cheap body panels, doors, fenders, and engines from donor cars. The key is to call ahead or use online inventory systems to find yards with the make and model you're targeting.
Local Auto Parts Stores For emergency repairs or common mechanical components (belts, hoses, basic fluids), national chains like AutoZone, O'Reilly, and Advance Auto Parts are convenient. However, their inventory is geared toward street- passenger cars, not the heavy-duty needs of a derby car.
| Source Type | Best For | Pros | Cons |
|---|---|---|---|
| Online Specialty Retailers | Safety gear, reinforced parts, performance upgrades | High-quality, derby-specific designs | Higher cost, shipping wait times |
| Salvage Yards | Body panels, engines, axles, cheap replacements | Extremely low cost, immediate availability | Time-consuming, no warranties |
| Local Racing Shops | Expert advice, same-day pickup for common items | Support local business, hands-on help | Limited selection, may be pricey |
| Online Marketplaces (eBay/Facebook) | Rare or specific parts, used racing components | Wide selection, potential for deals | Risk of fraud, inconsistent quality |
Your strategy should combine these sources. Build the core of your car with junkyard finds and bolt on critical safety and reinforcement parts from dedicated derby suppliers.

Honestly, the junkyard is my first and last stop. Nothing beats walking through rows of old cars with a toolbox, pulling a door off a Crown Vic for forty bucks. It’s cheap, and you learn how everything fits together. For the stuff that absolutely cannot fail—like your helmet or a roll cage—I’ll order from a proper derby shop online. But for everything else, it’s the yard.

I focus on safety first, so I buy those parts new from reputable racing suppliers. A five-point harness isn't something you gamble on. For the car's body and drivetrain, I search local classifieds and Facebook Marketplace for people parting out old trucks. You can often find a complete donor vehicle for a few hundred dollars, which gives you every part you'll need in one shot.

Check if there’s a local dirt track or derby group near you. The folks there are a goldmine of information. They’ll tell you which junkyards have the best prices, who’s selling used parts, and maybe even have spare pieces lying around. It’s all about community. They know what parts hold up best in a crash, which is knowledge you can’t just get from a website.

My process starts online with research. I figure out exactly what parts I need and which car models are compatible. Then, I hit the , calling every salvage yard within a hundred miles to check prices and availability. For the big items, I'll sometimes find a better deal on eBay than driving for hours. It's a mix of old-school legwork and using the internet to be smart about it.
