How To Put Trucks On A Skateboard: The Professional Assembly Guide
Mounting skateboard trucks requires precise alignment of the baseplate holes with the deck’s mounting pattern to ensure structural integrity and proper steering geometry. By following the standard 8-hole mounting pattern and applying correct hardware torque, you eliminate wheel bite risks and prevent premature deck stress fractures caused by loose or uneven pressure.
Essential Preparation and Hardware Requirements
Before attempting to mount your trucks, ensure you have the correct components matched to your deck width. Skateboard setups rely on standardized hardware dimensions, primarily the 7/8-inch or 1-inch bolt length. If you are using riser pads to prevent wheel bite, you must increase your hardware length accordingly to ensure enough thread passes through the nylon lock nuts for a secure grip.
- Required Tools: One 3/8-inch socket wrench or skate tool, and one 1/8-inch Allen key or Phillips head screwdriver depending on your bolt head type.
- Essential Components: One set of two skateboard trucks, eight mounting bolts and eight nylon-insert lock nuts (nylocs), and your skateboard deck.
- Optional Upgrades: Riser pads (1/8-inch or 1/4-inch) for increased wheel clearance and shock absorption, and speed washers for bearing alignment.
- Technical Benchmarks: Mounting holes on decks are universally spaced at 2.125 inches by 1.625 inches (the "old school" vs "new school" hybrid pattern). Verify that your trucks have six holes if you are using an older deck, though most modern trucks feature universal six-hole baseplates.
Precise Installation Workflow
The following steps outline the mechanical process for attaching trucks to a deck with maximum stability and structural safety.
Step 1: Preparing the Mounting Surface
Place your skateboard deck on a flat, stable surface, such as a workbench or a clean floor. Identify the nose and the tail of the board. The nose is typically longer and steeper, while the tail is shorter and flatter. Align your trucks so that the kingpins (the large bolts holding the bushings) face toward the center of the board. If the kingpins are facing outward toward the nose and tail, you will experience severe geometry issues, making the board nearly impossible to steer.
Step 2: Inserting the Hardware
Push your eight mounting bolts through the top of the deck’s grip tape side. If your bolts have a distinct color (many brands use one colored bolt to indicate the nose), place this bolt in the top-right or top-left position to help identify the front of the board during tricks. Press the bolt heads down firmly so they sit flush with the grip tape.
Step 3: Aligning the Baseplates
Turn the board over and align the holes in the truck baseplates with the protruding bolts. If you are using riser pads, slide them onto the bolts first, followed by the truck baseplate. Ensure the baseplate is flush against the deck or riser. If the holes do not align perfectly, verify that the truck kingpins are indeed facing inward.
Warning: Do not force a bolt into the baseplate if the alignment is off, as you risk stripping the bolt threads or the deck's wood grain, which can lead to a weakened mounting point and future deck failure.
Step 4: Securing the Lock Nuts
Place a nylon-insert lock nut onto each of the eight protruding bolt ends. Tighten each nut by hand until it makes contact with the baseplate. Using your 3/8-inch socket tool, tighten the bolts in a cross-pattern—much like tightening the lug nuts on a car wheel—to ensure even pressure distribution across the baseplate.
Pro-Tip: Do not overtighten to the point where the baseplate begins to deform or "sink" into the wood of the deck, as this creates stress risers that lead to pressure cracks. The nut should be tight enough that the bolt does not rotate, but the deck wood should remain flat.

Technical Specifications and Compatibility Standards
Understanding the relationship between deck width, truck axle length, and hardware is vital for performance. Use the following table to ensure your components are optimally matched for your specific riding style.
| Component | Standard Metric | Impact on Performance |
|---|---|---|
| Bolt Length | 7/8 inch | Ideal for setups without riser pads. |
| Bolt Length | 1 inch | Necessary for 1/8-inch riser pads. |
| Bolt Length | 1.25 inch | Used for 1/4-inch shock pads or risers. |
| Truck Width | 129mm - 149mm | Must match deck width within 1/4 inch. |
| Mounting Pattern | New School (1.625") | Modern standard for all professional decks. |
Common Installation Errors and Field Remedies
Even experienced skaters can face hardware issues during the installation process. Addressing these early prevents damage to the deck’s mounting holes.
- Root Cause: Stripped Bolt Threads. This usually happens when the nut is cross-threaded or tightened too aggressively with a power drill.
- Actionable Fix: Remove the bolt entirely and inspect the threads. If damaged, replace both the bolt and the nylon lock nut immediately. Never reuse a compromised nyloc nut, as it will lose its locking capability.
- Root Cause: Deck "Sinking" or Wood Cracking. Occurs when hardware is overtightened on soft wood or when riser pads are omitted.
- Actionable Fix: Loosen the hardware slightly. If the wood has already cracked, apply a small amount of wood glue to the area, clamp it, and allow it to dry for 24 hours before re-mounting.
- Root Cause: Uneven Steering or Pulling. Caused by baseplates being mounted slightly crooked or unevenly torqued.
- Actionable Fix: Loosen all eight nuts on the affected truck. Re-align the baseplate by sight or by using a straight edge against the board’s center line, then re-tighten in a cross-pattern.
Frequently Asked Questions
Do I need to use riser pads when installing trucks?
Riser pads are not strictly mandatory unless you are riding large wheels (over 54mm) or prefer a very loose truck setting. If you notice your wheels contacting the underside of the deck during sharp turns—a condition known as wheel bite—you should install 1/8-inch riser pads to gain the necessary clearance.
Why do some skateboard bolts have different colors?
The different colors on skateboard hardware are primarily for orientation, allowing the rider to instantly identify which end of the deck is the nose versus the tail. This is purely a functional visual cue and has no impact on the structural performance of the truck or the board.
Can I reuse old hardware when changing trucks?
You can reuse hardware if the bolts are not stripped and the nylon inserts inside the lock nuts still provide sufficient resistance. However, because nyloc nuts lose their gripping strength every time they are removed and reinstalled, it is considered best practice to use a fresh set of hardware whenever you perform a full truck swap.
What is the purpose of the nylon insert in the lock nut?
The nylon insert creates friction against the threads of the bolt, which prevents the nut from vibrating loose due to the high-impact nature of skateboarding. You should never replace these with standard metal nuts, as they will vibrate off within minutes of riding, resulting in lost components and potential injury.
How tight should the mounting bolts be?
The bolts should be tightened until the nylon lock nut is fully engaged with the threads and the baseplate is firmly held against the board without gaps. The wood of the deck should not be compressed or "dimpled" under the bolt heads; if you see the wood bowing, the hardware is significantly overtightened.
