CZ Chains RS Ultra-Reinforced 219 Pitch O Ring Kart Chain - 114 Link

The CZ Chains RS Ultra-Reinforced 219 Pitch O Ring Kart Chain delivers long-lasting performance by combining reinforced construction with O ring sealing to maximise power transfer and minimise wear. It uses hardened Chromium KSJ treated axles, heavy-duty side links, and internal lubrication retention to create a low-friction, ultra-high durability drive solution.Here are the key features, benefits, and outcomes you can expect from this chain:Reinforced side links: Manufactured from high-strength steel to prevent flex and fatigue, helping maintain consistent chain geometry, resulting in more efficient torque delivery throughout the race.Chromium KSJ treated axles: Hardened surface treatment enhances wear resistance and mechanical strength, reducing internal movement and limiting stretch, so you maintain optimum chain tension for longer.O ring sealing: Integrated O rings seal in lubrication between links and rollers, reducing internal friction and metal-on-metal contact, leading to extended service life and consistent operation across multiple sessions.Ultra-precise pin and bushing fit: Tight manufacturing tolerances reduce internal friction and energy loss, which minimises drag and helps convert more engine output into rear axle rotation.Low-friction chain design: Surface finish and material pairing are engineered to reduce resistance between moving parts, lowering rolling resistance and improving acceleration response.High fatigue strength: The complete assembly is designed to withstand repeated high-load shocks without deformation, which protects your sprockets and reduces the risk of unexpected failure mid-race.Extended service life: Reduced wear and stretch rates mean you carry out fewer adjustments and replacements, saving time and keeping drivetrain performance consistent over more race sessions.Race-proven in top-level competition: The RS chain has been used to win multiple European and World titles, so you can rely on it to perform when the pressure is on.219 pitch sizing: Standard fitment for modern performance kart drivetrains ensures easy compatibility with your existing sprockets and hubs.In hard-fought race conditions where consistency and drivetrain reliability matter, the O ring sealing helps maintain internal lubrication and reduce friction, keeping the chain running freely across long sessions. When you're pushing hard through sprints or running multiple heats in a day, the RS chain s reduced friction and reinforced build keep wear under control and help maintain consistent performance. Its resistance to stretch means you don t have to worry about power loss or potential breakages late in the session. By staying in grade longer, it supports maximum engine output without unnecessary drag.If you're aiming for less downtime and more consistent power delivery, this chain gives you a practical advantage. Its build quality and precision design work together to keep your race kart performing at its best for longer.
