Improve shifting response with the MFactory R&D (Synchrotech®) Carbon Sleeve Set

Recognising the extremely high cost of OEM replacement synchroniser parts, MFactory R&D (Synchrotech®) have took it upon themselves to design and develop their own range of high performance OEM replacement parts.

Forged from a higher tensile steel, our Sliders are both stronger and lighter than the OEM equivalent.

For the synchros, we utilize a carbon-carbon lining technology initially developed for the Aerospace Industry which acts as braking material during gear engagement. This allows for quicker and more precise shifting and prolongs the life of your gear set.

After several years of Research & Development on our championship winning race cars, we are proud to offer the most technologically advanced Synchros & Sliders on the market.


  • Sliders are Forged from high tensile steel
  • Synchros are made from high strength Japanese brass
  • Synchros are Carbon-Carbon Lined (not just a coating!) for increased durability
  • 100% larger surface contact area for increase performance
  • More aggressive lock angle for effortless high rpm shifting
