Mould King Sets: Trucks, Cranes, Engines and More

What Mould King makes

Mould King makes brick-built models of machines. In our data, every Mould King listing is a brick set: plastic bricks, beams and other parts that you follow a booklet to build into one large model. The models are mostly things with engines and wheels. Construction equipment, trucks, cars and engine blocks make up most of the lineup, with two roller coasters and one toy shotgun model alongside.

That's a narrow range, and it's deliberate. If you like building a machine you can recognize from the road or a job site, the lineup is built around that. If you want a castle, a spaceship or a character, this isn't the brand.

The grid above shows the 22 Mould King listings live on Amazon US as of 2026-10-23. To compare Mould King with other brick makers by piece count and age, see the building blocks type page.

Mould King sets: the lineup by kind of machine

Piece counts below come from the listings. We haven't checked them against the maker. Where a listing gives a set number, it's in the name.

Construction machines

This is the biggest group:

• Heavy Crane: 8,506 pieces, the largest count in our Mould King data
• 17008 Heavy Duty Crane: no piece count stated in our data, in the same high price tier as the Heavy Crane
• Crawler Crane LR13000: 14+
• 17070 Large Excavator: 4,767 pieces
• Heavy Duty Mining Dump Truck: 2,558 pieces
• 17036 Excavator and Bulldozer 2 in 1: 2,239 pieces, two models from one box by the name
• 17105 Concrete Mixer Truck: 2,165 pieces, 14+
• 19023 Motor Grader: 1,109 pieces, 14+

Two cranes sit in the highest price tier of the whole lineup. Most of the others sit a tier below.

A crane at 8,506 pieces isn't a weekend project for most people. It's a season. A motor grader at 1,109 pieces is a more reasonable first look at the brand.

Trucks

• 13082 Pickup Truck: 3,695 pieces, 14+
• 19015T Trailer Truck: 3,399 pieces, 14+
• 10037 Semi Truck: two listings with the same set number, one stating 1,814 pieces and 14+, the other stating 1,797 pieces
• Flatbed Truck with Airplane: 1,468 pieces, 14+

Here's a small thing that the math teacher in me can't skip. Two listings, same set number, 17 pieces apart. I'd ask a student to show their work on that one. Maybe one count includes spares, maybe one is a typo, maybe they're different versions. The listings don't say. Read the one you're actually buying, and if the count matters, ask the seller before you order.

Cars

• Classic Supercar: 1,557 pieces
• 10114 Classic Cars: 14+, no piece count in our data
• Climbing Car: 14+, no piece count in our data

Cars are the smaller end of the lineup. A car model also fits on a normal shelf, which a crane does not.

Engines

• V8 Engine: 2,718 pieces
• 10171 V8 Engine: 14+, in the lowest price tier of any Mould King set in our data
• V8 Twin-Turbo Engine: no count or age in our data

Lucho saw the engine sets and was interested for the first time all week. "An engine with no fuel, no oil and no exhaust," he said. "Finally, one Marisol will let past the paint shelf." Then he asked if anyone checks the firing order. Nobody on this site can answer that from a listing.

Roller coasters

Two listings are called Roller Coaster at 3,646 pieces. One carries set number 11014, the other doesn't show a number in our data. Same name, same count. If you see both in the grid, compare the listing photos before you choose.

The shotgun model

The 14016 Double-barreled Shotgun is a 1,015-piece brick model of a double-barreled shotgun. It doesn't state an age in our data. It's a display model built from bricks. Think about where it will sit and who will see it, and read the box for the age before buying it for anyone under 14.

How to pick a Mould King set

Big brick sets ask more of you than smaller ones. Here's how I'd narrow it down.

1. Age first. Every stated age is 14+. Twelve listings don't state one. Don't hand any of these to a younger kid because the subject looks like a toy truck. Read the box.
2. Piece count second. For a first Mould King build, the sets around 1,000 to 2,000 pieces are the sensible start: the Motor Grader, the Flatbed Truck with Airplane, the Classic Supercar or one of the Semi Truck listings.
3. Then space. A 4,000- or 8,000-piece build needs a table you won't need back for weeks. Measure the shelf where the finished model will live, too.
4. Then the subject. Pick the machine you'd actually look at every day. You'll be looking at it for a while.

One more note on the subject line. A crawler crane, a mining dump truck and a motor grader are machines most of us only see behind a fence on a job site. These are the versions you're allowed to touch, and nobody needs a hard hat.

Set numbers: the most useful line on the box

Thirteen of the 22 Mould King listings in our data carry a set number, like 13082, 17070 or 19023. That number is worth more than it looks.

A set number tells you two listings are the same model, even when the titles are worded differently. It's how you'd find instructions if a booklet gets lost, and it's how you'd describe the set if you ever need help with a missing part. When two listings show the same number with different piece counts, like the two 10037 Semi Truck listings, the number tells you they're meant to be the same model, and the counts tell you to read closely.

Write the set number on the box lid before the box gets recycled. Better yet, tape it to the underside of the finished model. Somebody will ask what it is.

A first build and a long build, side by side

Here's what the two ends of the lineup look like, using only listing facts.

The 19023 Motor Grader lists 1,109 pieces and ages 14+. It's a single machine, and at that count it's a project you can see the end of. It's the kind of set that tells you whether you enjoy this brand's style of build before you commit to a bigger one.

The Heavy Crane lists 8,506 pieces, close to eight times as many, and doesn't state an age in our data. That's a long build with a long booklet and a lot of bags. It suits someone who already knows they like big machine models and has the space for a large one when it's done.

Most of the lineup sits between those two. If you're unsure, start low. A finished small model is more fun than a half-finished big one.

Mould King as a gift

For a teen of 14 or older, or an adult who likes machines, a Mould King set can make sense as a gift, as long as you match three things: the age on the box, a piece count they'll actually finish, and the kind of machine they'd want on a shelf. A car fan gets a car. A kid who stops to watch every road crew gets an excavator or a grader.

Skip it as a gift for someone who has never built a large brick set and isn't sure they want to. A 1,000-piece set is a reasonable test. A 4,000-piece set is a commitment you're making for them.

Building a big brick set: a few habits

None of this comes from a Mould King manual. It's what helps with any large brick set.

• Keep bags closed until their step. Big sets are usually split into numbered bags. Open one bag at a time.
• Use a tray. A shallow tray keeps small parts from rolling off the table and into the carpet.
• Mark your place. Big booklets run long. A sticky note on the current page saves ten minutes of hunting every session.
• Sort by part, not color, for gray builds. Machines are mostly gray and black. Color sorting doesn't help much. Shape sorting does.
• Check the build before the next bag. A wrong part on page 40 shows up on page 200, and it's a long way back.

The table is the real cost of a big build. Count it in weeks. A model that has to be packed up every night gets built about half as often, which in my house is about never.

Small parts and the age label

Check the age label on the listing. Toys with small parts are a choking hazard for children under 3. A big brick set has hundreds or thousands of small pieces. If younger kids live in the house, build at a table they can't reach and sweep the floor after every session.

Who should skip Mould King

Skip it for anyone under 14. That's every stated age in our data.

Skip the cranes and the large excavator if you want to finish a model this month. At 4,767 and 8,506 pieces, those are long builds.

Skip it if you want a playable toy more than a display model. The listings describe models of machines. They don't state play features in our data, so don't plan on any.

And skip it if you want a licensed character or a theme from a movie. Mould King's lineup in our data is machines and vehicles.

What our data doesn't show

• Motors or remote control. No listing in our data states a motor, a remote or an app. If you want a powered model, read the listing carefully.
• Finished size. No listing in our data states the built model's length or height.
• Ages on 12 of 22 listings. Missing, not a warning.

If a listing adds any of these, our grid picks it up on the weekly check.
