The KO Propo 35564 aluminium gear set swaps in firm metal components for the BSx4S-one10 Grasper2, aiming to deliver steadier response and less wear over time. This is a common upgrade for pilots who demand repeatable steering inputs.
Metal gears resist tooth deformation and keep mesh geometry stable, which preserves servo accuracy during continuous use. That stability benefits competitive driving where consistent input is important.
Gears are manufactured to match BSx4S-one10 Grasper2 specifications and typically fit with a standard gear change process. Take care with gear alignment and use appropriate grease to achieve the best lifespan.
