Koswork Tekno CNC 13mm Pistons 2x1.7mm SCT/MT410 2.0 EB/ET410 RC Shock Piston - KOS04081-41

The Koswork KOS04081-41 CNC shock pistons are 13mm replacement pistons machined to fit Tekno SCT410, MT410 2.0, EB410, and ET410 models. Each piston features a 2x1.7mm hole configuration, which determines oil flow rate and directly affects how the shock absorber responds to bumps and track surface changes. If your current pistons are worn, cracked, or you want to experiment with a different damping setup, these are a direct-fit option for the Tekno platform.

Key Features

• CNC machined construction for consistent dimensions and accurate hole sizing across both pistons
• 13mm diameter matches the shock body size used on Tekno SCT410, MT410 2.0, EB410, and ET410
• 2x1.7mm hole layout controls shock oil flow and damping response
• Sold as a pair, providing enough to service one shock absorber or replace a single worn piston on two shocks

What's Included

• 2x Koswork KOS04081-41 CNC 13mm shock pistons (2x1.7mm hole configuration)

What You Need

• Tekno SCT410, MT410 2.0, EB410, or ET410 model requiring 13mm shock pistons
