TruckSpareParts is a truck spare parts knowledge hub built for the people who keep heavy commercial vehicles earning their keep: fleet operators, workshop owners, and the parts buyers and distributors who supply them. We publish practical, research-grounded guides on air brake systems, preventive maintenance, parts purchasing, and the industry shifts that will change what sits on your shelves over the next decade.
The site exists because most of what you find when you research a truck part online is either a thin product listing or a generic article written a long way from any workshop floor. Somewhere between the two sits the information a professional actually needs: which brake chamber fits which axle, how to cross-reference an OEM number without getting burned, when an aftermarket part is the smart buy and when it is not. That gap is what we set out to close.
Who this site is for
Heavy commercial vehicles are working assets. Every day a truck spends in the bay instead of on the road costs real money, and the wrong part — wrong spec, wrong quality, wrong supplier — is one of the most common reasons a two-hour job turns into a two-day one. We write for three groups of readers:
- Fleet operators and maintenance managers who make OEM-versus-aftermarket decisions at scale and need parts strategies that hold up across hundreds of vehicles, not just one.
- Workshop owners and technicians who need correct fitment, realistic service intervals, and honest guidance on which jobs belong with a professional — especially on safety-critical systems like spring brakes.
- Parts buyers and distributors evaluating suppliers and product ranges in a global commercial vehicle aftermarket that industry analysts such as The Business Research Company value at over $100 billion a year.
What this truck spare parts knowledge hub covers
Our guides are organized into four topic areas. Each one links to detailed, standalone articles you can hand to a technician or a purchasing colleague as-is.
| Topic | What you will find |
|---|---|
| Air brake systems | Compressors, air dryers, brake chambers, slack adjusters, ABS and EBS — how the pneumatic system works and how to keep it working. |
| Maintenance | Preventive maintenance schedules, clutch systems, wheel hubs and bearings, cooling systems — keeping downtime planned instead of surprise. |
| Buying guides | OEM versus aftermarket, cross-referencing part numbers, judging quality, and building a purchasing strategy that survives an audit. |
| Industry trends | Euro 7, electrification, ADAS mandates, and what changing regulations mean for the parts on your shelf. |
How we research and review our guides
Every guide starts with primary sources: manufacturer service documentation, parts catalogs, and the regulations that actually govern this industry — UNECE Regulation 90 for replacement brake linings and discs, the EU General Safety Regulation for ADAS requirements, Euro 7 for emissions-related components. Where we quote a figure, we have verified it. Where we could not verify one, we say so in plain language instead of inventing a number.
We are just as deliberate about safety. Air brake systems store enough spring energy to injure or kill, and some procedures — caging a spring brake chamber, for example — have no place in a casual how-to. When a job belongs in the hands of a trained technician, our guides say exactly that.
Who supports this site
Transparency matters, so here it is plainly: TruckSpareParts is supported by Vaden Original, a Turkish manufacturer of OEM-quality aftermarket parts for heavy commercial vehicles. Founded in 1968 in Konya, the company today exports to more than 110 countries and has produced over one million air brake compressors — the kind of production history that gives us direct access to engineering-level knowledge about how these parts are designed, manufactured, and tested.
That support does not change what we publish. Our guides are written to help you make good parts decisions regardless of brand. When OEM is the right call, we say so. When we point to product ranges — such as Vaden's catalog of OEM-compatible air brake and engine components, which spans more than 12,000 references — it is as a concrete example of what a serious aftermarket range looks like, not an instruction to buy. No honest publication claims an aftermarket part is right for every situation, because it is not.
Where to start
If you are new here, the guides index lists everything we have published in one place. If you have a quick question — what "OEM-quality" actually means, how aftermarket parts affect warranty, how to spot a counterfeit — the FAQ page covers the questions we hear most often from fleets and workshops.
And if there is a topic you want covered — a component, a regulation, a buying decision that keeps coming up in your fleet or your shop — we want to hear about it. This site improves the same way a good workshop does: one solved problem at a time.
