The Tekno RC TKR6003B Aluminum Non-Vented Shock Caps (2-Pack) are high-performance suspension components designed to improve shock consistency and durability across a wide range of Tekno RC vehicles. CNC machined from black anodized aluminum, these non-vented caps trap air inside the shock above the bladder, creating increased rebound and a more progressive damping feel compared to vented designs. This results in better control over large jumps and improved stability on hard landings, making them ideal for high-grip tracks and aggressive driving conditions. Compatible with multiple Tekno platforms including EB48, ET48, NB48, NT48, SCT410, and MT410 series vehicles, they serve as a direct replacement or upgrade for enhanced suspension tuning and long-lasting performance.
