Transmission Reinforcement

It doesn't matter whether it's a RB gearbox from Nissan or an R154 from Toyota. The original transmission is not designed for the power and torque that can be achieved through tuning. From 400 HP upwards, the original transmissions will fall apart sooner or later. Our SPEEDTEK gear reinforcements make the original gears ready for over 800 hp and change the translation. The SPEEDTEK HULK kits include reinforced gears, synchronizer rings and all necessary bearings and seals. The gearbox must therefore be opened and new gearbox oil is required. The clutch type does not have to be changed, but a reinforced clutch is still necessary for the high performance.
