Description

This mini spool is designed to enhance traction and power distribution by replacing the spider gears in a differential, permanently locking both axles together. It is crafted from durable 4130 steel (or high-quality stainless steel, according to another retailer) for longevity and reliable performance, capable of withstanding tough conditions. It is engineered for precise fitment and typically requires no drilling for installation.
