Nissan Skyline RB25 - RB26 RB30 & VG30 Z31 Z32 5th Gear Set ONLY
A shorter 5th gear specifically engineered for motorsport use. This gear ratio is optimized to keep the engine within its power band during high-performance driving, providing improved acceleration and better gear-to-gear transitions. Ideal for drag racing, circuit racing, and other forms of motorsport, a close-ratio short 5th gear allows drivers to maintain momentum and reduce RPM drop between gears. This results in a more responsive and aggressive driving experience, making it the perfect upgrade for those chasing lap times or quick passes down the strip.
A longer 5th gear specifically engineered for road use. This gear ratio is optimized to reduce engine RPM while cruising on the highway, thereby minimizing fuel consumption and enhancing fuel efficiency. By lowering the engine speed at highway speeds, drivers can achieve better fuel economy without sacrificing performance or drivability.

Superfinishing is a metalworking process that improves surface finish and workpiece geometry. This is achieved by removing just the thin amorphous surface layer left by the last process with an abrasive stone to grind the gears and other parts ; this layer is usually about 1 μm in magnitude. Superfinishing, unlike polishing which produces a mirror finish, creates a cross-hatch pattern on the workpiece.
Advantages of superfinishing include: increasing part life, decreasing wear, closer tolerances, higher load bearing surfaces, better sealing capabilities, and elimination of a break in period.
