Depending upon your driving requirements, J's Racing has developed a variety of sets of final gears from 3.9 to 5.1 gear ratio. From street, autocross, drag racing, short track racing to long track racing, your customer can choose the one which will perfectly match the type of Final Gear Set they require. The combination of WPC treatment and PIP coating on the surface dramatically improves durability, heat generation characteristics and quietness. The set includes reinforced ring gear bolts (10 pieces) which enables tightening torque -11.0kg fm and prevents differential gear related problems. J's Racing recommends using the special differential distance collar.
WPC treatment - Wide Peening and Cleaning. Widely used in motor sports including F1, Le Mans, cart, and drag racing vehicles. By firing the ultra fine particles towards the surface of a product at very high speed, thermal discharge brings the repeated effect of heat treatment and tempering in a very short time. The surface of the product produces a new ionic structure and becomes harder and more tenacious. At the same time, it creates a hardened layer of depth and works against metal fatigue.
PIP coating - Power Impact Plating. J's Racing has chosen this coating that perfectly matches the WPC treatment and brings the product durability to the ultimate levels desired. PIP produces a special layer by oxidizing the powder and enables it to achieve the HV 1500 degree of hardness and 900°C thermal resistance. Furthermore, the coating penetrates deep into the surface thus dramatically prolonging its effectiveness.
