| Product Description | Material: Driven gear: DLC processed / Ring gear: WPC processed Reduction ratio 4.777 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. By applying DLC coating to the driven gear and WPC processing to the ring gear, we succeeded in giving good initial familiarity and high durability that have never been seen before. DLC has many features, but it is a coating whose main purpose is to improve the slidability of metals. "Improved slidability" means to improve slippage and reduce wear. It can be expected to reduce frictional heat, improve durability by preventing seizure, and improve response. The combination of DLC coating that reduces friction loss and WPC treatment that improves fatigue strength and kinesis achieves both dramatic improvement in durability and reduction in friction loss. The effect of DLC and WPC suppresses the oil temperature, avoids the danger of differential blow, and makes it possible to reliably extend the overhaul cycle. Recommended for endurance races and time attacks that use high grip tires, including those who drive a lot on the circuit. Includes 10 dedicated reinforced ring gear bolts that can strengthen the tightening torque more than genuine ring gear bolts. Prevents loosening of ring gear bolts, which is a major factor in differential blow. (What is DLC coating) Diamond Like Carbon is an abbreviation of Diamond Like Carbon, which 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 general term for carbon thin films with high hardness, electrical insulation, infrared transparency, etc. similar to diamond synthesized by the gas phase synthesis method using ions, and was named in the 1970s. The structure of the DLC film is usually an amorphous structure containing a small amount of hydrogen, and is said to have diamond bonds and graphite bonds. ■ High hardness and excellent wear resistance ■ Low friction coefficient under no lubrication ■ When sliding, the mating material is worn and damaged. Does not allow (low opponent aggression) ■ Chemically inert and stable Does not cause seizure, adhesion, or welding ■ Not invaded even in a corrosive atmosphere (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. |
| 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. |
