Product Information
OS Giken close-ratio gear sets offer greatly increased gear strength, along with closer gear ratios to suit racing applications. The retention of normal synchromesh parts and a helical gear design means the gears are still almost as quiet as a standard gear set, so this is an excellent upgrade for street-driven vehicles too. 1st Gear: 2.578 2nd Gear: 1.772 3rd Gear: 1.289 4th Gear: 1.000 5th Gear: 0.821
Application List * Mazda RX-7 FC3S (R15M-D)
