Due to its ultra-fast shifting, a sequential gearbox still marks the gold standard for professional motorsport applications or pure trackday machines.

We've designed the JUBU sequential gearbox especially for the Lotus V6 environment, this is why it fits perfectly for the engine and the periphery of Lotus cars. It has been heavily tested within our mule cars and can handle loads of up to 900 Nm.

Usage & Benefits

• Ultra-fast shifting (depending on the gear only 50-80 ms)
• Very robust (designed and tested for up to 900 Nm of torque)
• Very high service life of 45-50h (when used in combination with the JUBU paddle shift system)
• Reduction of weight (the JUBU sequential gearbox weights only about 57kg - this is app. 17,5 kg lighter than the OEM manual 6-speed gearbox)
• 2 different ratios available, depending on the purposed use (options: "standard" or "short")
• Flatshift - a manual operation of the clutch is only necessary while shifting from 1st to 2nd gear, all other gears can be shifted via flatshift (changing of the gear on full load without operation of the clutch and without lifting the throttle)
• Fully compatible with the optional available JUBU paddle shift system
• Quick and easy dismantling of the driveshaft possible (without swinging out the wishbones)
• Easy to maintain and to revise (single gears, the final drive and the LSD can be changed quickly and easy)
• Fast & reliable availablility of spare parts (shipping within 24h possible)
