RC hobbyists looking for tougher drivetrain parts can fit the KO Propo 35572 Stainless/Aluminum Gear Set into the BSx4S-Grasper STD MAX servo to boost longevity and keep movements smooth under load. The set is aimed at users who push their servos in competitive or rough-use environments.
These gears combine stainless steel and aluminum to strike a useful balance between durability and mass. That pairing reduces wear while keeping rotating mass reasonable, and the precise tooth profiles support consistent, repeatable servo travel.
Made specifically for the BSx4S-Grasper STD MAX servo, this gear set is suitable for on-track racing and tough off-road use where reliable steering and control are required. Installation keeps stock geometry and works well for routine service or straightforward upgrades.
