Longboard Suspension Trucks: What Truck Angle, Bushings, and RKP vs TKP Actually Mean for Your Ride
When riders search for longboard suspension trucks, they’re usually looking for a smoother, more controlled ride. But longboard trucks don’t have springs or shocks. The “suspension” comes from how the components are tuned—and understanding that is the difference between a comfortable commute and a board that feels unpredictable.
This guide translates the specs—truck angle, bushing durometer, and truck type—into what you actually feel on the road: turning radius, stability, and vibration dampening.
What ‘Suspension’ Actually Means in Longboard Trucks
Longboard trucks don’t have mechanical suspension like a car. The dampening system is made of urethane bushings—small cushions inside the truck’s hanger that compress when you lean and rebound when you straighten. When people talk about longboard trucks with suspension, they’re describing a setup where bushing hardness, shape, and truck angle work together to absorb road vibration and control lean.
I get this question a lot: “I want a board that feels smooth over rough pavement, but I don’t know where to start.” Most of the time, the answer isn’t buying a special truck. It’s understanding how the parts you already have—and a few you can swap—change the ride feel. Think of it less like adding shock absorbers and more like choosing the right cushion for your weight and terrain.
For a full overview of the component ecosystem, see our main longboard trucks category. There, you can compare hanger widths, baseplate materials, and complete kits.
Truck Angle: The Biggest Factor in Turning Radius
The baseplate angle—measured in degrees—is the spec that most directly controls how your board turns. It’s the primary thing to get right for your riding style.
- 50° baseplate angle: This is the standard on most complete longboards. It gives a wider, more responsive turn radius. You’ll feel a livelier, more carvy lean, which is ideal for cruising, campus commuting, and low-speed maneuverability. It feels more “active” under your feet.
- 40° baseplate angle: A lower angle means a tighter, more stable platform at higher speeds. The turn radius is narrower per degree of lean, which gives you more control when you’re going fast. This is better for downhill, fast commutes, or anyone who prefers a planted, predictable feel over nimble carving.
What this means for you: match truck angle to your speed and terrain, not to brand reputation. If your daily route is a flat campus path at moderate speeds, 50° is a practical default. If you regularly hit hills or want minimal turn for a fast, straight commute, 40° is worth considering. Most riders never need to change their stock angle unless they’re deliberately optimizing for a specific style. You can learn more about how deck shape pairs with truck style in our types of longboards guide.
Bushings: Where the ‘Suspension Feel’ Actually Comes From
Bushings are the heart of your longboard’s dampening system. They’re the urethane cushions that control how much effort it takes to lean and how the board rebounds. Swapping them is the most cost-effective way to change your ride feel.
| Bushing Spec | What You Feel | Best For |
|---|---|---|
| Softer durometer (80A–87A) | More compression, easier lean, better vibration absorption, less high-speed stability. | Cruising, rough pavement, riders under 180 lbs wanting max comfort. |
| Harder durometer (90A–97A) | Stiffer lean, more precise rebound, less dampening, more control at speed. | Heavier riders, faster riding, downhill, anyone wanting a “tighter” feel. |
| Barrel shape | More stability and rebound control; holds the truck’s centerline. | Use boardside (between hanger and baseplate) for a planted base. |
| Cone shape | Easier turn initiation, more flex and lean range. | Use roadside for a looser, carvier steering response. |
The most common “suspension” setup for cruising is a barrel/cone combo: a barrel bushing boardside for stability and a cone roadside for easier turn initiation. This balances dampening with responsiveness.
In practical terms, if your ride feels too stiff and hard to turn, or too loose and wobbly at speed, your bushings are the first thing to check. A bushing swap costs about $8–$15 and can transform a board. For new riders starting their first build, our beginner longboard guide explains how to choose a complete setup with components that match your weight.
RKP vs TKP Trucks: Which One Rides Smoother?
The two main truck architectures—reverse kingpin (RKP) and traditional kingpin (TKP)—have fundamentally different steering geometries that affect their “suspension” characteristics.
| Truck Type | Steering Feel | “Suspension” Characteristic | Typical Use |
|---|---|---|---|
| RKP (Reverse Kingpin) | More turn per degree of lean; fluid, carving-oriented response. | Better vibration dampening at commuting speeds due to longer effective wheelbase and bushing orientation. | Most longboards, cruisers, commuting, carving. |
| TKP (Traditional Kingpin) | Snappier, more direct response; lower ride height. | More direct ground feedback; feels less “dampened” but more precise for tricks and quick maneuvers. | Street skateboards, some cruisers, portable boards. |
For a smooth, dampened commute, RKP trucks paired with soft barrel bushings give the closest feel to a suspension system. TKP trucks are more responsive but transmit more road texture directly to your feet.
You might also hear about precision longboard trucks. These have CNC-machined hangers and baseplates that reduce slop (play in the system). The result is a tighter, more predictable lean—not necessarily a “smoother” ride, but a more consistent one. For most commuters, proper bushing tuning on standard cast trucks delivers all the dampening they need. The difference between a good longboard and a skateboard setup is part of the core decision in our longboard vs skateboard comparison.
Choosing Truck Setup by How You Ride
The right “suspension” setup depends on your route, not a brand’s marketing. Here’s how to translate common scenarios into component choices.
Campus or Short Commute (Smooth Pavement)
Setup: 50° RKP trucks, 85A–87A barrel/cone bushings.
Why: Responsive for tight turns between buildings, forgiving over minor cracks, easy to push.
City Commute (Rough Pavement)
Setup: 50° RKP trucks, 80A–85A full barrel bushings.
Why: Softer barrels absorb vibration from brick and asphalt seams. Full barrel shape adds stability for moderate speeds.
Weekend Carving on Hills
Setup: 50° RKP trucks, 87A–90A barrel bushings.
Why: Balances lean and rebound for controlled carves without feeling too loose on descents.
Faster Riding or Mild Downhill
Setup: 40° RKP trucks, 90A–93A barrel bushings.
Why: Lower angle and stiffer bushings prioritize stability and reduce turn sensitivity at speed.
Portable Cruiser (TKP Trucks)
Setup: Stiffer bushings (90A+) if using TKP.
Why: TKP geometry is already more responsive; softer bushings can make it feel twitchy. You compensate with hardness.
The core tradeoff is simple: more dampening (softer, lower angle) means more comfort but less precision at high speeds. The right answer depends on where you ride and how fast you go. A buyer I helped last year started with a soft cruising setup. Six months later, he found himself riding faster in parks and feeling unstable. He didn’t need a new board—just harder bushings and a lower-angle baseplate. Your riding evolves; your setup can too. Find boards built for commuting and cruising in our longboard category.
Do You Actually Need ‘Suspension Trucks,’ or Just Better Bushings?
This is the buying decision. Most riders searching for longboard suspension trucks don’t need a specialty truck. They need bushing tuning.
Most complete longboards ship with generic bushings tuned for a 150-pound rider. If you’re heavier or lighter, the ride will feel off—too stiff or too loose. The fix is an $8–$15 bushing swap, not a $50+ truck upgrade.
Actual suspension trucks with spring mechanisms exist in niche markets, but they’re not necessary for the dampening most riders seek. If your current trucks have visible lean slop or the hanger wobbles side-to-side, that’s a truck quality issue—a sign you might need new trucks. But if the hardware is solid and the ride just feels too harsh or too loose, start with bushings.
Before spending $50+ on precision longboard trucks, try a bushing swap matched to your weight and riding style. It’s the single biggest upgrade for ride feel, per dollar spent.
Common Questions, Answered Straight
What are longboard suspension trucks?
Longboard trucks use urethane bushings—not mechanical springs—as their dampening system. The term “suspension trucks” usually refers to a truck setup (angle, bushing hardness, shape) tuned for a smoother, more controlled lean and vibration absorption, not an actual suspension mechanism.
Do I need precision trucks for a smoother ride?
Not for most commuting. Precision trucks (CNC-machined) reduce slop and improve lean predictability, but bushing durometer and shape matter more for ride comfort. For the average commuter, proper bushing tuning on standard cast trucks is sufficient and far cheaper.
What bushing durometer should I use for cruising?
For most cruising riders under 180 lbs, 80A–87A durometer is a good range. Heavier riders (180+ lbs) should look at 87A–90A. A barrel/cone combo shape offers a balance of carve and stability. Always consider your weight and the roughness of your pavement.
Should I replace my trucks or just the bushings?
Start with the bushings. If your hanger is solid and the baseplate angle suits your riding, a $10 bushing swap will change ride feel more than a $50 truck upgrade. Only consider new trucks if your current ones have visible slop, wobble, or are the wrong width for your deck.
