| Product Description | Material: Driven gear: DLC processed / Ring gear: WPC processed Reduction ratio 4.444 Driven gear DLC processed Ring gear WPC processed Shot peening processed Dedicated reinforced ring gear bolt (KRG-S1) Included A total of 5 types of lineup from 3.9 to 4.7. It is possible to select the gear ratio according to the stage. Widely compatible with street, gymkhana, low, medium and high speed circuits. It is possible to improve the acceleration power and response without removing the power band, which directly leads to time up. It is an essential item to win. (Specifications) The combination of DLC coating that reduces friction loss and WPC treatment that improves fatigue strength and kinesis dramatically improves durability and reduces friction loss. By using DLC processing for the driven gear and WPC processing for the ring gear, we have succeeded in giving good initial familiarity and high durability that have never been seen before. By reducing the friction loss, the oil temperature can be suppressed, the danger of differential blow can be avoided, and the differential overhaul cycle can be reliably extended. Recommended for endurance races and time attacks that use high-grip tires, including those who often run sports on the circuit. Includes 10 dedicated reinforced ring gear bolts that can strengthen the tightening torque more than genuine ring gear bolts. Prevents the ring gear bolt from loosening, which is a major cause of differential blow. (What is DLC coating) An abbreviation for Diamond Like Carbon, it is a technology that can make a surface with an unprecedented low wear coefficient by forming a nano-level thin film on a metal surface. DLC is a thin film (several microns), has low wear resistance (high hardness), low wear coefficient adhesion resistance, infrared transmission, design, biocompatibility, gas barrier resistance, corrosion resistance, etc. It is attracting attention in many fields because it has various functions. (Effect of WPC processing) Abbreviation for Wide Peening and Cleaning, special processing that is also used for F1. By injecting a special shot at high speed and locally raising it to the recrystallization temperature, the work strengthening of the heat treatment effect and forging effect is instantly repeated, and the residual austenite in the metal surface layer is converted to martensite and recrystallized. Miniaturize the tissue. This creates a structure with high hardness and toughness on the metal surface, which makes it possible to significantly increase the surface altitude. In addition, by increasing the internal compression residual stress, fatigue strength can be increased and gear chipping can be prevented. Furthermore, the dimples (smooth and very fine irregularities) that arrive during processing create an oil pool and prevent wear to a minimum. By injecting a special shot at high speed and locally raising it to the recrystallization temperature, the work strengthening of the heat treatment effect and forging effect is instantly repeated, and the residual austenite in the metal surface layer is converted to martensite, recrystallized, and the structure is fine. I will do the conversion. This creates a structure with high hardness and toughness on the metal surface, which makes it possible to significantly increase the surface altitude.

| Remarks | Engine: F20C F22C Pinion gear x 1 Ring gear x 1 Reinforced ring gear bolt x 10 Be sure to use the attached reinforced ring gear bolt. (Ring gear bolts cannot be reused) It is strongly recommended to use the SPL differential distance collar at the same time. We recommend precision embedding at a professional shop. |
