Keeping your trailer on the road starts with having the right parts when you need them. Whether you’re replacing a damaged component, performing routine maintenance, or upgrading equipment, correctly identifying the trailer part you need can save valuable time, money, and downtime.
At ILoca Services, our experienced parts team helps customers every day find the correct semitrailer parts, even when they don’t know the exact part number. Here’s how to make the process easier and when it’s time to call the experts.
Why Part Numbers Matter
Trailer manufacturers often use multiple versions of similar components throughout the life of a trailer. Brake chambers, suspension components, lighting systems, landing gear, doors, and air system parts may look nearly identical while having different specifications.
Providing the correct part number helps ensure:
· Faster order processing
· Accurate fitment
· Reduced downtime
· Fewer returns and exchanges
· Improved trailer performance and safety
Where to Find Trailer Part Numbers
Many trailer parts have identifying information stamped, engraved, labeled, or cast directly onto the component.
Common places to look include:
Suspension Components
Check for manufacturer tags, stamped numbers, or labels on:
· Air bags
· Shock absorbers
· Torque arms
· Suspension hangers
Brake System Parts
Look for identification numbers on:
· Brake chambers
· Slack adjusters
· ABS components
· Brake valves
Lighting Components
Most LED lights and harnesses include:
· Manufacturer part numbers
· DOT markings
· Product labels
Landing Gear and Couplers
Look for:
· Data plates
· Manufacturer tags
· Serial numbers
Trailer VIN Plate
Your trailer’s VIN plate often provides valuable information that helps identify original equipment components.
Take Photos When Possible
Not sure what you’re looking at? A clear photo can often tell our parts specialists everything they need to know.
Helpful photos include:
· The damaged part
· Any visible part numbers
· The trailer VIN plate
· The mounting location
· Overall trailer view
The more information you can provide, the faster we can help identify the correct replacement.
Common Information to Have Ready
Before contacting a trailer parts department, gather as much of the following information as possible:
· Trailer make
· Trailer model
· Trailer year
· VIN number
· Part number (if available)
· Photos of the component
· Description of the issue
Even if you don’t have all of this information, don’t worry. Our team can often help narrow down the correct part through a few simple questions.
