Slappy Trucks Size Guide: Dimensions, Size Chart & Everything You Need to Know

Choosing the right skateboard trucks is one of the most important parts of building your setup. If you're considering Slappy Trucks, you're probably wondering which size you need and how they differ from other truck brands.

Known for their quick turning response, excellent grind clearance, and minimal break-in time, Slappy Trucks have quickly become a favorite among street skaters, transition skaters, and curb enthusiasts alike.

This guide covers everything you need to know about Slappy Truck dimensions, sizing, and features so you can choose the perfect pair for your setup.

Why Choose Slappy Trucks?

Slappy Trucks are designed with performance in mind and are known for:

• No break-in time

• Better grind clearance than traditional standard kingpin trucks

• Less wheel bite

• Quick turning response

• Reduced kingpin hang-ups on Smith grinds, Feebles, Hurricanes, Bennetts, and Barleys

Slappy achieves this through its unique geometry, which provides a greater "Slappy Angle" and increased clearance between the kingpin and obstacles.

Slappy Angle and Grind Clearance Explained

One of the features that sets Slappy apart is its increased grind clearance and reduced kingpin interference.

A higher Slappy Angle means the truck is less likely to catch or snag during grinds, particularly on tricks such as:

• Smith Grinds

• Feeble Grinds

• Hurricane Grinds

• Bennett Grinds

• Barley Grinds

This additional clearance helps provide smoother and more predictable grind performance.

Slappy ST1 Classic vs Hollow Trucks

Slappy offers two primary options:

ST1 Classic

• Traditional construction

• Maximum durability

• Slightly heavier feel

• Great for all-around skating

ST1 Hollow

• Hollow kingpin and axle

• Reduced overall weight

• Same geometry and performance characteristics

• Ideal for skaters looking for a lighter setup

The Hollow models save approximately 20 grams per truck depending on the size.

Are Slappy Trucks Good?

Slappy Trucks have developed a strong reputation among skaters because they combine:

• Fast turning similar to looser truck brands

• Excellent grind clearance

• Reduced kingpin hang-up

• Minimal break-in period

• Stable performance across street, transition, and curb skating

Whether you're skating ledges at your local park or learning slappies on a curb, Slappy Trucks offer a unique feel that many skaters quickly grow to love.
