6 Best Skateboard Truck Washers For Precision Alignment

A slight rattle in your trucks during a technical descent or a sluggish response when carving through a tight corner often points to one tiny, overlooked culprit: worn or mismatched washers. These small components act as the critical interface between your bushings and the truck hanger, dictating how smoothly your board translates movement into a clean turn. By upgrading to a precision-engineered washer set, you stabilize your setup and ensure that your energy input yields consistent, predictable board performance on every ride.

Bones Hardcore Flat Washers: Best Overall Pick

Bones Hardcore Flat Washers earn the top spot for their exceptional consistency and high-grade metal construction. These washers are engineered to provide a perfectly flat surface, which allows the bushings to compress evenly under load without side-loading or pinching.

For riders who prioritize a stable, predictable feel, these are the gold standard. They eliminate the “squishy” sensation that often plagues cheaper, stamped metal options, offering a crisp, snappy response that is vital for technical street skating or park sessions.

Choose these if you prefer a predictable, linear turning experience that stays consistent from the first push to the last drop-in. They are an essential upgrade for any rider looking to lock in their truck geometry without introducing unnecessary complexity.

Independent Genuine Parts: Top Cup Washers

When it comes to refined turning geometry, Independent Genuine Parts remain the industry benchmark. These cup washers are designed with a specific depth that cradles the bushing, providing a more restrictive and controlled transition compared to flat alternatives.

By locking the bushing into place, these washers increase the rebound feel, making them ideal for skaters who want a tight, responsive setup that returns to center instantly. They excel in scenarios where agility and quick flick are the primary objectives.

These are the right choice for riders who demand a classic, locked-in feel for transition and bowl riding. If your skating style involves heavy carving or high-speed maneuvers where stability at the apex of a turn is mandatory, these cup washers deliver the necessary support.

Venom Machined Flat Washers: Precision Pick

Venom takes the manufacturing process a step further by machining these washers for an exact, burr-free finish. Unlike mass-produced stamped washers that can feature uneven edges, these precision components ensure that the bushing interface is perfectly level.

The difference lies in the smoothness of the turn; these washers reduce internal friction, allowing for a more fluid interaction between the kingpin and the bushing. This is particularly noticeable when performing long, drawn-out carves where subtle weight shifts are required.

Serious downhill skaters and longboarders who obsess over their suspension setups will appreciate the refined performance here. If you are tuning your trucks for a specific speed-based application where even the smallest amount of drag is undesirable, these machined washers are the definitive upgrade.

RipTide Backing Washers: Ideal for Longboards

RipTide has long been synonymous with high-end bushing chemistry, and their backing washers reflect that same dedication to performance. These washers are specifically designed to provide a wider base of support for the larger bushings often used on longboards and carving setups.

This increased surface area prevents the bushing from deforming under the intense pressure of a deep, high-speed lean. By supporting the full perimeter of the bushing, they maintain the integrity of the urethane and extend its lifespan significantly.

These are an essential acquisition for long-distance pushers and downhill riders. If your gear setup includes soft, high-rebound bushings, these backing washers will prevent them from bulging out the sides, ensuring your trucks remain predictable even under significant stress.

Khiro Skateboard Cup Washers: Best Value Buy

Khiro provides a practical, no-nonsense solution that balances budget considerations with reliable performance. These cup washers are available in various sizes and depths, allowing for fine-tuning that is rarely seen at this price point.

They offer a robust construction that stands up to the rigors of daily use without warping or deforming over time. While they lack the high-end machining of premium options, they provide a distinct improvement over the generic, soft metal washers that come stock on most complete trucks.

These are the perfect choice for the rider who maintains multiple boards or frequently experiment with different bushing durometers. If you want to keep a supply of reliable, versatile washers in your gear bag without overspending, Khiro is the most sensible route.

Thunder Trucks Rebuild Washers: Most Durable

Thunder Trucks are known for their distinct geometry and high-performance capabilities, and their replacement washers are built to match that reputation. These washers are heat-treated to resist bending, making them arguably the most durable option on the market.

For skaters who lean heavily into their trucks or subject them to high-impact landings, these washers won’t flatten or fail under pressure. This durability ensures that your alignment stays dialed in throughout the season, regardless of how aggressively you ride.

These washers are for the heavy hitter who is tired of replacing bent or warped hardware every few months. If your primary goal is gear longevity and you want a set-it-and-forget-it solution for high-impact street skating, these are an undeniable investment.

Flat vs. Cup Washers: Finding the Right Fit

The fundamental difference between flat and cup washers lies in how they manage the bushing’s expansion. Flat washers allow the bushing to compress and bulge naturally, which provides a looser, more fluid turn that is often preferred by those who enjoy a “surf-like” feel.

Cup washers, conversely, encapsulate the bushing, limiting its lateral expansion and forcing the urethane to resist compression more aggressively. This results in a much tighter, more restricted turn that offers a stronger return to center and increased stability at higher speeds.

Choosing between the two depends on the terrain you frequent. Flat washers are excellent for loose, nimble street setups, while cup washers are the preferred choice for those demanding maximum control in high-speed transition or downhill scenarios.

Installing Washers for Perfect Truck Alignment

Proper installation begins with a clean kingpin and a perfectly circular bushing. Place the washer onto the kingpin with the flat side—or the cup opening—facing the bushing to ensure full, even contact across the surface.

Avoid over-tightening the kingpin nut, as excessive force can cause the washer to dig into the urethane and impede the natural motion of the truck. Aim for a snug fit where the bushing is held securely, but still allows for the free movement required to lean and carve effectively.

Check the alignment after the first session to ensure the washers haven’t shifted or caused the bushings to skew. A balanced setup results in a symmetrical turn, so inspect your boards periodically to keep the hardware centered and fully functional.

When to Replace Your Worn Skateboard Washers

Washers rarely fail catastrophically, but they do experience “metal fatigue” over time, especially after thousands of cycles of compression. If you notice your trucks feel inconsistent or seem to “stick” mid-turn, it is time to inspect your washers for signs of wear.

Look closely for any signs of cupping, warping, or sharp burrs that have developed along the inner edge. A washer that is no longer perfectly flat or a cup that has become deformed will create an uneven load on your bushings, leading to lopsided performance and premature bushing failure.

Whenever you replace your bushings, it is standard practice to also replace your washers. Pairing old, deformed washers with new bushings is a common mistake that prevents fresh urethane from performing to its full potential, essentially wasting the investment you made in the upgrade.

Pairing Washers and Bushings for Best Control

The relationship between your washers and your choice of bushing is critical for achieving optimal control. Softer, lower-durometer bushings are particularly sensitive to washer types, as they rely on a stable base to prevent excessive distortion during high-intensity maneuvers.

If you are using a softer bushing for increased carvability, a wider, flat washer often provides the best support without sacrificing the lively feel of the urethane. For harder, high-durometer bushings meant for stability, a deeper cup washer helps enforce that “locked-in” sensation required for high-speed discipline.

Experimenting with these combinations is part of the craft of fine-tuning your board. Take the time to swap components, feel the difference in the turn, and adjust based on the specific terrain of your next trip, whether it is a smooth local skatepark or a rough-hewn canyon descent.

Investing in high-quality washers is one of the most cost-effective ways to refine your ride and improve the longevity of your truck setup. By selecting components that match your skating discipline, you ensure that your board responds with the precision needed for every turn and transition. Keep your gear dialed in, trust your instincts, and enjoy the ride.
