Penny Board Trucks: Size, Types & Replacement

Penny board trucks are a critical component, influencing both the turning radius and overall stability of these compact skateboards. The size of penny board trucks, often measured in millimeters, must be appropriately matched to the deck width to ensure optimal performance. Replacement of these trucks may become necessary due to wear and tear from frequent use, especially when executing advanced maneuvers in skate parks. Understanding the different types of penny board trucks available, including their construction materials and mounting styles, is essential for riders seeking to personalize their board’s handling characteristics and improve their skating experience.

Understanding Penny Board Trucks: A Comprehensive Guide

Penny board trucks are a fundamental component of any penny board setup, directly influencing the board’s turning ability, stability, and overall riding experience. Selecting the right trucks, understanding their types, and knowing when and how to replace them are crucial for both beginners and experienced riders. This article will delve into the specifics of penny board trucks, covering sizing, types, and replacement considerations.

Sizing Matters: Finding the Right Width

The size of penny board trucks is primarily determined by the width of the board’s deck. Overhang – where the wheels extend beyond the deck – should be minimal, as it can compromise stability and increase the risk of wheel bite (when the wheel rubs against the board, causing sudden stops). Undersized trucks can also lead to instability and reduced control.

The ideal truck width is usually within a narrow range. Penny boards traditionally come in two main deck sizes:

• 22-inch Penny Boards: Typically require trucks with a hanger width of around 3 inches (76mm) to 4 inches (102mm) and an axle width of 5 inches (127mm) to 6 inches (152mm).

• 27-inch Nickel Boards: Are better suited to trucks with a hanger width between 4 inches (102mm) to 5 inches (127mm) and an axle width of 6 inches (152mm) to 7 inches (178mm).

Here is the summary as a table:

Deck Size	Hanger Width (Approx.)	Axle Width (Approx.)
22-inch Penny	3" – 4" (76mm – 102mm)	5" – 6" (127mm – 152mm)
27-inch Nickel	4" – 5" (102mm – 127mm)	6" – 7" (152mm – 178mm)

Types of Penny Board Trucks: Standard vs. Reverse Kingpin

While the overall design of skateboard trucks remains relatively consistent, subtle differences can significantly impact performance. The two primary types of trucks you’ll encounter for penny boards are standard kingpin and reverse kingpin trucks.

• Standard Kingpin Trucks (SKP): These are the most common type of truck found on penny boards. The kingpin, the central bolt holding the truck together, faces inwards towards the deck. SKP trucks generally provide a more stable feel and are suitable for cruising and carving.

• Reverse Kingpin Trucks (RKP): In RKP trucks, the kingpin faces outwards, away from the deck. This design typically results in a more responsive and fluid turning experience, often preferred for carving and downhill riding. However, RKP trucks can sometimes feel less stable at higher speeds.

The choice between SKP and RKP trucks ultimately depends on personal preference and riding style. Beginners often find SKP trucks more predictable, while experienced riders might opt for RKP trucks for enhanced maneuverability.

Replacing Your Penny Board Trucks: When and How

Penny board trucks, while durable, are subject to wear and tear over time. Knowing when to replace them is crucial for maintaining safety and performance.

Here are common indicators that your trucks need replacing:

1. Visible Damage: Cracks, bends, or significant corrosion on the trucks themselves.
2. Worn Bushings: Bushings are the rubber or polyurethane cushions that allow the trucks to turn. If they become cracked, deformed, or excessively compressed, turning will be difficult and unpredictable.
3. Kingpin Issues: A bent or stripped kingpin will prevent you from tightening or loosening the trucks properly.
4. Loose or Stripped Axle Nuts: Difficulty tightening the axle nuts can lead to wheel wobble and potential wheel detachment.

The Replacement Process:

Replacing penny board trucks is a relatively straightforward process:

1. Gather Your Tools: You’ll need a skate tool or appropriately sized wrenches.
2. Remove the Wheels: Use your skate tool to remove the axle nuts and detach the wheels from the trucks.
3. Remove the Old Trucks: Unscrew the four mounting bolts that secure the trucks to the deck.
4. Install the New Trucks: Align the mounting holes of the new trucks with the holes on the deck and secure them with the mounting bolts. Ensure the trucks are facing the correct direction (the kingpin should be facing the nose and tail of the board).
5. Reattach the Wheels: Place the wheels back onto the axles and tighten the axle nuts. Avoid overtightening, as this can damage the bearings.
6. Adjust Truck Tightness: Use the kingpin nut to adjust the tightness of the trucks to your desired level. Tighter trucks will be more stable but less responsive, while looser trucks will be more maneuverable but less stable.

So, whether you’re cruising down the boardwalk or just need to freshen up your ride, understanding your penny board trucks is key. Hopefully, this breakdown helps you choose the right size, identify the type you need, and tackle any replacements like a pro. Happy skating!
