The short answer: Longboard wobble at high speeds is usually caused by a combination of loose trucks, soft bushings, incorrect weight distribution, or worn-out components. It’s a common issue that can be fixed by adjusting your setup and improving your riding posture.
Speed wobble is that unsettling shimmy that starts in your board’s rear trucks and can quickly turn into a violent oscillation. It happens when your board’s stability is compromised. Think of it like a pendulum: when you’re going fast, small inputs from your feet, legs, and body can create a resonance that amplifies the wobble. The key is to keep your weight centered and your body relaxed, but also to make sure your equipment is tuned for speed.
If your trucks are too loose, they’ll allow the board to turn too easily, which is great for carving but terrible for high-speed stability. The bushings (the rubbery parts inside the trucks) are your main suspension. If they’re too soft for your weight, they’ll compress too much and cause instability. A quick fix: tighten your trucks a quarter turn at a time until the wobble subsides. But be careful not to over-tighten, or you’ll lose steering ability.
Where you place your feet matters. If you’re standing too far back, you’ll put more weight on the rear truck, which can cause it to steer erratically. Ideally, you want your front foot to be near the front truck, and your back foot just behind the front truck, with your weight slightly forward (about 60% on the front foot). This stance gives you more control and helps dampen wobble.
Unevenly worn wheels can cause vibrations that translate into wobble. Also, if your wheels are too hard or too small, they may not absorb road imperfections well. Check your wheels for flat spots or uneven wear. Rotating them regularly can help extend their life and maintain smoothness.
Every longboard has a comfortable speed range. If you’re pushing beyond what your board is designed for, you’re asking for trouble. For example, a board with a short wheelbase (distance between trucks) is less stable at speed than a longer one. If you’re consistently hitting high speeds, consider a board designed for downhill or freeride, which typically has a longer wheelbase and wider trucks.
Start by tightening your trucks incrementally until you feel a balance between turnability and stability. If you’re heavier (over 180 lbs), consider upgrading to harder bushings (like 90a or 95a). Lighter riders may prefer softer bushings (80a-85a) but should still keep them snug enough to prevent wobble.
Keep your knees bent and your body low. This lowers your center of gravity and makes you more stable. Keep your arms out for balance. Always look ahead, not down. A common mistake is to tense up when wobble starts; instead, relax your legs and let the board settle.
Loose bolts on your trucks or baseplates can cause play that contributes to wobble. Use a skate tool to check all nuts and bolts before each ride, especially if you’ve been riding for a while.
If you’ve done all the above and still get wobble, it might be time to upgrade. Look for trucks with a wider axle and a lower angle (like 50-degree or less) for stability. Also, consider a board with a longer wheelbase. If you’re in the market for a new board, check out this comprehensive longboard buying guide for recommendations on stable speed boards.
If you start to wobble, resist the urge to slam on the brakes or jerk the board. Instead, gradually slow down by dragging your foot or using a controlled carve. Shift your weight forward to the front truck, which can help dampen the oscillation. Practice emergency slow-downs in a safe area so you’re prepared.
While you can reduce it significantly, some wobble may always exist at extreme speeds. The goal is to make it manageable and not let it escalate. With the right setup and technique, you can enjoy high-speed rides confidently.
Yes, wider trucks provide a larger foot platform and more stability. However, they can also make turning less responsive. Look for a balance that suits your riding style.
Bushings can wear out over time, losing their rebound. If you notice they’re cracked, flattened, or feel overly soft, replace them. Generally, you might need new bushings every 6-12 months depending on usage.
