This set includes six precision-machined shims crafted from durable steel, designed to fine-tune the tolerances within your RC vehicle's drivetrain components, specifically differentials and gearboxes. These shims are crucial for reducing slop and ensuring smooth operation, which directly impacts power delivery and extends the lifespan of gears by preventing premature wear. Their exact dimensions of 12.2mm inner diameter, 15.9mm outer diameter, and 0.5mm thickness make them ideal for achieving optimal gear mesh and reducing drivetrain noise in CEN vehicles.
