DESCRIPTION
We have pioneered a groundbreaking development by introducing the first-of-its-kind dog engagement 5th and reverse gear for the Nissan Skyline/300ZX 5-speed transmission.
This innovative gear system offers two distinct ratio options tailored to different driving needs.
The first option is a short 5th gear designed for motorsport use. This shorter gear ratio optimizes acceleration and performance, making it ideal for racing applications where quick shifts and high RPMs are
essential for competitive advantage.
The second option is 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.
Our dog engagement 5th and reverse gear for the Nissan Skyline/300ZX 5-speed transmission offers versatility and customization, allowing drivers to tailor their driving experience based on their specific needs, whether it's on the track or the road.
If you're currently using our 1st to 4th kit and are interested in adding these new components to your transmission.
5th Gear Ratio Options:
-
Short – 0.814 (Mainshaft 22 / Countershaft 27)
-
Long – 0.677 (Mainshaft 21 / Countershaft 31)
We now offer Isotropic Superfinishing on all our Speedtek Products.
(This process will increase the time from when we could dispatch the kit, please email us if you have any questions)
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.
Our solid 6-month unconditional warranty program for all our manufactured gearsets, you can be confident that your investment is well-protected.
Our extended warranty program is available, for more information : Extended Warranty Program now Available with our Performance Transmiss – Speedtek Auto Racing
