If your board feels twitchy, or it won’t turn, or you keep getting wheelbite, the fix is almost always your trucks, not your ability. Truck tightness and bushings control how your board turns and how stable it feels. This guide explains what is actually happening when you adjust the kingpin, how to choose bushings, and how to dial in a setup that matches how you skate.

What trucks actually do

A truck turns because the hanger pivots against rubber bushings, squeezed by the kingpin nut. Tighten the nut and you compress the bushings harder, so the truck resists turning. Loosen it and the truck pivots more freely. That single nut is the main dial, but the bushings underneath set the whole character.

Loose versus tight: the real trade-off

Looser trucks

Looser trucks turn sharply and carve well, which suits cruising, transition, and tight lines. The cost is stability. At speed, very loose trucks develop speed wobbles, the side-to-side shimmy that throws riders off. Loose also risks wheelbite, where the wheel touches the deck on a hard turn and stops it dead.

Tighter trucks

Tighter trucks feel planted and predictable. Many street skaters run them firm because it makes landings feel locked in and reduces wheelbite. The cost is turning effort; you steer more with your shoulders and less with your ankles, and slow carving feels stiff.

There is no single correct setting

The right tightness depends on your weight, wheel size, and what you skate. A heavier rider compresses bushings more, so they often need firmer bushings to get the same feel as a lighter rider on a softer set.

Bushings: the part most people ignore

Bushings have a durometer rating, the same hardness scale used for wheels. Softer bushings (lower number) turn easily and feel lively. Harder bushings resist more and feel stable. Crucially, bushing hardness is a better tool than the kingpin nut. Cranking the nut down to fake stability just crushes soft bushings and wears them out fast. If you want more stability, fit harder bushings rather than over-tightening.

Bushing shape matters too. Conical or barrel shapes lean into a turn differently, but for most riders the practical move is: keep the stock hardness if it feels fine, go harder if you want stability, go softer if you want more turn.

A real dial-in example

A rider gets a new setup and it feels dead and stiff. They loosen the kingpin nut a quarter turn at a time, testing after each. Two turns in, the board carves nicely but now bites the wheel on sharp turns. They add riser pads to raise the deck, which stops the wheelbite without losing the turn. That iterative process, small change then test, is how you actually find your setting. Guessing once rarely works.

Common mistakes and how to fix them

Over-tightening to stop wobble. This crushes bushings and kills turn. Fix: use harder bushings and a moderate nut setting instead.

Running the nut so loose the hanger rattles. If the kingpin nut spins freely, the truck has play and feels sloppy. Fix: tighten until the nut just seats against the washer, then adjust feel from there.

Ignoring wheelbite until you slam. Fix: add riser pads, run a smaller wheel, or tighten slightly. Bite is a hard stop that pitches you forward.

Setting one truck different from the other by accident. Mismatched trucks feel unstable and you blame yourself. Fix: match front and back unless you intentionally run a looser front for carving.

Step-by-step setup checklist

  • Start both trucks at the same tension: tighten the kingpin nut until it just meets the washer.
  • Stand on the board and lean side to side; you should turn with moderate effort.
  • Too stiff to carve? Loosen a quarter turn and retest.
  • Wobbly at speed or biting the wheel? Tighten slightly or fit harder bushings.
  • Still fighting wheelbite after tightening? Add riser pads or a smaller wheel.
  • Check the nut is not past the end of the kingpin threads; if it is, your bushings are worn out.
  • Recheck after a few sessions; new bushings break in and loosen.

Conclusion and next step

Trucks are a tuning problem, not a set-and-forget part. Your next step: this week, adjust in quarter-turns and test after each change instead of guessing. If you hit the limits of the nut, swap the bushings; that is the real dial. Once it clicks, your board will finally feel like an extension of your feet.

FAQ

Should beginners run loose or tight trucks?

Slightly on the tighter side. Beginners benefit from stability while learning balance, and firmer trucks reduce surprise wobbles. Loosen gradually as your balance improves and you want more turn.

How do I know if my bushings are worn out?

Look for cracks, a cracked or crushed shape, or a kingpin nut that runs out of thread before it firms up. Worn bushings feel vague and won’t hold a setting no matter how you adjust the nut. Replace them; they are cheap.

Why does my board turn one way better than the other?

Usually uneven bushings or an uneven nut setting between sides, or a bushing seated crookedly. Rebuild the truck, make sure the bushings sit flat in the seat, and match tension side to side.

Can I stop speed wobbles just by tightening?

Tightening helps a little, but harder bushings and good riding posture do more. Crouch, keep your weight centred and forward, and don’t over-crank the nut, which only wears bushings faster.
