Koswork Tekno CNC 13mm Pistons 2x1.8mm SCT/MT410 2.0 EB/ET410 RC Shock Piston - KOS04081-42

The Koswork KOS04081-42 CNC machined 13mm shock pistons are precision-made replacement parts for Tekno SCT410, MT410 2.0, EB410, and ET410 models, offering a direct-fit solution for worn or damaged shock internals. Each piston features a 2x1.8mm hole configuration, which controls oil flow through the shock and directly affects how the suspension responds across different track surfaces. If your Tekno buggy, truck, or e-buggy is developing inconsistent damping or your current pistons are showing wear, swapping in a fresh set of CNC machined shock pistons is the right starting point.

Key Features

• CNC machined from solid material for tight tolerances and a consistent fit inside 13mm shock bodies
• Two pistons per pack, each drilled with a 2x1.8mm hole pattern to regulate damping characteristics
• Direct replacement for the shock pistons used across the Tekno SCT410, MT410 2.0, EB410, and ET410 platforms
• Precision machining ensures repeatable oil flow behaviour, keeping shock performance consistent across both pistons
• Retains the factory damping profile — suited to drivers wanting like-for-like restoration rather than a tuning change

What's Included

• 2x Koswork CNC 13mm shock pistons (2x1.8mm hole pattern)

What You Need

• Compatible Tekno shock assembly (SCT410, MT410 2.0, EB410, or ET410)
• Appropriate shock oil for reassembly
• Basic RC tool kit for shock servicing
