The spider gear shaft itself is crafted from high-grade stainless steel, ensuring exceptional durability, corrosion resistance, and long-term reliability even under heavy mechanical stress. The accompanying protector is made of top-quality Alu7075 aluminum alloy—a material renowned for its outstanding strength-to-weight ratio, excellent wear resistance, and ability to withstand impact, making it ideal for reinforcing critical components.
A common feedback from users is that the connection area of traditional spider gear shafts tends to be overly weak, leading to frequent breakage during use. To address this critical issue, we have integrated a dedicated Alu7075 protector into the design. This protector adds targeted reinforcement to the vulnerable connection area, significantly enhancing the shaft’s overall structural integrity and preventing premature failure.
To ensure long-lasting performance and avoid operational disruptions caused by loose fasteners, the four screws included with the product are pre-coated with Loctite adhesive. This pre-gluing process creates a secure, vibration-resistant bond, keeping the screws firmly in place even during high-intensity use.
With the holder protector properly assembled, the process of inserting the spider gear into the differential case (diff case) becomes significantly easier.
