Why Would You Need A 4Terrain Upgrade?
 
Firstly, it increases the torque capacity through a high clamp pressure plate and secondly, it assists with cooling which in turn enables the friction material to operate at lower temperatures and therefore at a higher coefficient of friction. This system greatly enhances the torque capacity and longevity of the clutch.

It's not uncommon for LandCruiser 78 and 79 owners to modify their vehicle for more extreme off-road driving, and when these modifications are done it's important to also upgrade the clutch system. For these enthusiasts, a clutch modification that can handle greater torque while also increasing heat dissipation and providing a superb pedal feel is essential. 4Terrain has been engineering different options for Toyota LandCruiser  for years, one of the most popular products being in the 4Terrain Ultimate brand. 
 

Why grind when you can replace?

 

There are three main technical reasons to replace a conventional flywheel instead of grinding it.

1. Issues caused by a bad grind. There are various issues that can come out of a poor grind, these include:
   • Flywheel surface being too smooth which can cause shutter or slipping.
   • Incorrect flywheel step or recess ground; in the case where a flywheel is not flat the recess or step must be maintained. Failure to do this can cause engagement or disengagement issues.
2. Risk of catastrophic failure; in situations where the flywheel is placed under extreme heat damage can occur to the steel microstructure weakening the flywheel which can lead to cracking or destruction of the flywheel.
3. Decreasing the overall stack height. Modern actuation systems have limited bearing height adjustment so after 2-3 grinds the overall stack height of the clutch system can be reduced enough to cause disengagement issues.
