Billet selector forks 1-6 for the Nissan GTR is made from a solid billet piece of high strength steel and carved to perfection. Its precision in design and engineering means it is lighter and stronger and can withstand any beating in the toughest conditions. It has been chemically treated to be extremely durable and finished with REM isotropic superfinishing to reduce friction and decrease heat
Stronger material
CNC milled for precision
Reduced friction
Easy installation
REM isotropic superfinished
Latest heat treatment process technology
Every part is coded for easy identification
- Precision forged GR6 gears 1-6
- Cluster
- Main input shaft
- Output shaft
Benefits:
- Stronger gears
- Quiet operating
- wide gears for strength and durability
- spline assembled design
- Reduced friction
- advanced grinding & heat treatment process technology
- Design: AutoCAD and SolidWorks software to design tooth profiles.
- Motorsport grade steel
- Accurate grade of gear: Gear grinding to reach JIS-B1702 1(JIS-B1702-02 N5)
- Optional Oerlikon coating available for extra cost
Notes
- Linney Heavy Duty transmission oil to be used with Linney Gears
- Due to custom spec Gear profile a custom EcuTek TCM Flash is required (adjustment is not available on Cobb at time of writing). TQ on shifts must be set accurately
- Gears are for Motorsport off road use only

Following years of detailed design, analysis and testing we are excited to announce a completely
new generation of GT-R gear sets. Designed and manufactured in the UK, the range offers enhanced
ground tooth geometry delivering exceptional torque characteristics and a greatly enhanced duty
cycle. This has been achieved by bringing together the very best materials and treatments developed
over many years. heavy duty gears made from Aero/Mill spec material incorporating the latest tooth
profiles machined on state of the art CNC machinery, heat treated and Duplex shot penned for
maximum strength and reliability
• Designed, engineered & manufactured in England
• DIN 3 quality
• New 2nd, 3rd, 4th 5th, 6th gear design to reinforce and hold more power, improved helical
angle for low noise operation
Revised & improved teeth spec – Wider Gears, Thicker teeth
• Motorsport grade Alloy aerospace steel (as used in F1, DTM, GT500) single melt case
hardened all gears 1-6 & cluster
• State of the art motorsport machining inc 6 axis gear grinder- kleinberg Holfer viper 500. A
Viper K 500 machine costs in excess of £500k one of only two machines in UK, very few
outside of Germany, these allow the highest level of gear grinding possible. Capable of
finishing gears to incredible accuracy, meeting even the extreme tolerances required for
high end motorsport. Most GT-R gears on the market suffer from poor quality grinding and
not to the tooth root where most cracks/breakages occur
• Heat Treatment
• Gears shot peened and ground for maximum strength
• Oerlikon DLC Coating available as option

How to measure backlash
* professional install is essential clearance/lash/shimming required.. incorrect set up, running low on oil, Locked/damaged ETS will cause terminal damage to your FWD.. must be used with billet side bearing to prevent bolts backing out (oem side bearing can crack).
There is no warranty stated or implied due to the stresses placed on your vehicle by performance parts and our inability to monitor their use, tuning, or modification.
