TrailMaster Go Kart Unboxing Guide: Inventory Every Part Before You Begin
Estimated Reading Time: 12 minutes
Few things are more exciting than the day your new TrailMaster go kart arrives. After waiting for shipping, seeing that freight truck pull into your driveway is a pretty exciting moment. Before you grab a wrench and start bolting parts together, however, take a few minutes to prepare.
At GoKartMasters, we've been selling TrailMaster go karts and mini bikes for over 20 years. During that time, we've helped customers assemble more than 5,000 machines. We've answered thousands of phone calls, solved countless assembly questions, and learned where first-time builders usually run into trouble.
The good news? Nearly all of those problems can be avoided by slowing down and taking inventory before you begin.
This guide will walk you through exactly how we prepare every kart in our own shop, what parts people commonly think are missing, how to inspect for shipping damage, and a few tips that aren't found in the factory manual.
Before You Touch a Wrench...
I want to tell you a quick story.
Back in school, many of us had a teacher who handed out a "test" with all sorts of strange instructions. The first question might say:
Stand up.
The next might tell you to clap your hands.
Another might tell you to spin around.
Pretty soon half the class was doing embarrassing things while everyone else laughed.
The very last instruction said:
Read all the instructions before beginning. If you've read this far, ignore every question above and quietly sit at your desk.
The exercise wasn't really about the test. It was teaching an important lesson:
Read the instructions before you start.
Building a go kart is the same way.
One of the best things you can do is watch our complete assembly video before opening your toolbox. Even if you don't remember every detail, you'll know what's coming next. There won't be any surprises halfway through the build.
A few minutes of preparation can save hours of frustration.
Step 1: Photograph Everything
This is one of the most important tips we can give.
Before cutting any straps or removing the crate, take pictures.
Take photos of:
- The entire shipping crate
- Every side of the crate
- Any dents or damage
- The unopened kart
- Every loose part
- Every hardware package
Hopefully you'll never need those pictures.
But if something was damaged during shipping, or you later wonder where a part went, you'll be glad you have them.
We've even had customers discover that a "missing" part was sitting in the background of one of their photos the whole time.
Pictures are free.
Replacement parts and freight claims are not.
Step 2: Check for Shipping Damage First
Don't immediately begin removing hardware.
Instead, inspect the kart.
Look carefully for:
- Bent frame tubing
- Broken plastic
- Cracked windshield
- Damaged mirrors
- Scratched body panels
- Bent cargo rack
- Torn seats
Minor paint scratches happen occasionally during freight shipping.
Major damage is much less common, but if you find any, stop and contact us before continuing.
Step 3: Remove All the Plastic
The factory does an excellent job protecting the kart for shipping.
Unfortunately, that means there's a lot of wrapping to remove.
Take your time.
Cut away:
- Plastic wrap
- Foam
- Tape
- Zip ties (only when appropriate)
- Protective film
Be careful not to scratch painted surfaces while using a utility knife.
Step 4: Lay Every Part Out
This is exactly how we do it in our shop.
Once everything is unpacked, we don't immediately start building.
Instead, we spread every component out neatly around the work area.
It may look like it takes extra time, but it actually saves time because you're not constantly hunting for the next bracket or bolt.
Think of it like laying out ingredients before cooking a meal. Professional chefs call it mise en place—having everything in its place before you begin. The same principle makes assembling a go kart much smoother.
Step 5: Gather Your Tools
Having the right tools nearby makes assembly much easier.
We recommend having:
- Metric socket set (up to 24 mm)
- Ratchet
- Metric wrenches
- Flat-head screwdriver
- Rubber mallet
- Low-pressure tire gauge
- Needle-nose pliers
- Utility knife
- Shop rags
You don't need an expensive toolbox.
You just need the right tools ready before you begin.
Step 6: Inventory Every Part
Now it's time to compare what you have with the packing list.
Check for all major components first.
You should have items such as:
- Front wheels
- Rear wheels
- Roll cage bars
- Side bars
- Cross bar
- H-bar
- Cargo rack
- Rear shock
- Front fenders
- Rear fenders
- Steering wheel
- Mirrors
- Battery
- Hardware package
- Keys
- Owner's manual
- Certificate of origin
After you've confirmed the larger pieces, begin counting your hardware.
Yes—it takes a few extra minutes.
Yes—it is worth it.
If you discover you're missing a bolt after the kart is half assembled, you'll spend far longer trying to identify which one it is.
The Three Parts Customers Think Are Missing Most Often
After helping customers for two decades, we've noticed the same three "missing parts" come up again and again.
1. The Rear Shock
The rear shock isn't actually missing.
It's usually tucked behind the brake pedal during shipping.
Many customers don't notice it until they've already called us.
Take a careful look before assuming it's gone.
2. Spindle Hardware
The spindle hardware is commonly zip-tied directly to the spindle.
Because it's wrapped tightly against the frame, it's easy to overlook.
Before reporting missing hardware, inspect every zip tie on the kart.
3. Shock Bolts
This one is different.
Shock bolts can occasionally loosen during shipping.
Every now and then, they fall out of the crate before delivery.
That's why we recommend checking for them before throwing away any packaging.
If they truly are missing, simply contact us and we'll help get you taken care of.
Don't Throw Away the Packaging Yet
It can be tempting to drag the cardboard and plastic straight to the trash.
Don't.
Wait until the kart is completely assembled.
We've seen:
- Hardware hidden in cardboard folds
- Mirrors wrapped inside foam
- Small bags stuck to tape
- Bolts trapped underneath protective packaging
You'd be surprised what turns up during the final cleanup.
What If Something Really Is Missing?
First—
Don't panic.
Most "missing parts" turn out to be hiding somewhere on the kart.
If you've checked everything and still can't find the part:
Text us for the fastest response.
You can also send an email.
When contacting us, include:
- Your name
- Your order number
- Photos of the area
- Photos of the crate (if applicable)
- Photos of the hardware you've already located
Pictures help us determine whether a part was left off, misplaced, or damaged during shipping.
The more information you provide, the faster we can help.
Pro Tips From the GoKartMasters Shop
These aren't in the factory manual, but they've saved our customers a lot of headaches over the years.
Watch the assembly video before you begin.
You'll understand the entire process before turning the first bolt.
Remove the vent line.
Certain models have a service bulletin recommending removing the vent line and capping the nipple. Be sure to follow the current GoKartMasters service bulletin for your model.
Learn how to start the kart before your first ride.
Understanding the proper starting procedure makes your first start much less frustrating.
Buckle unused seat belts.
Loose seat belts can become caught in the rear tires and be damaged. Keep unused belts buckled whenever they aren't being worn.
Teach kids to keep their arms inside.
It's one of the first safety rules we teach every family. Riders should keep their hands, arms, feet, and legs inside the vehicle while it's moving.
Adjust the chain.
Don't assume it's perfect just because it's new. Chain tension should be checked during assembly and again after the first few hours of riding, since new chains naturally stretch as they wear in.
Frequently Asked Questions
Should I count every bolt?
Yes. It only takes a few minutes and can save a lot of frustration later.
Can I throw the crate away?
Wait until assembly is complete. Small parts sometimes hide in the packaging.
What if I can't find a part?
Inspect every zip tie, every piece of foam, and every cardboard fold before contacting support.
Should I watch the video or read the manual first?
Watch the video first, then follow along with the printed guide as you assemble the kart. The combination gives you the clearest understanding of what's ahead.
Ready for the Next Step?
Once you've confirmed that every part is present, your work area is organized, and your tools are ready, you're ready to begin assembling your TrailMaster.
In the next guide, we'll walk you through installing the roll cage correctly, including one simple mistake that causes more frustration than almost anything else: tightening the bolts too soon.
