Special vents remove dirt and clutch lining debris automatically, preventing it from accumulating in the clutch bell and causing premature wear to clutch bell and linings. They aid in cooling of the clutch bell as well.The clutch bell features a significantly reinforced wearing surface whichguarantees dimensional stability even under high loads!Since this clutch bell is single-piece machined from bar stock there is no weld bead on the inside of the face plate.

With the Big Scale-EXTREME an adjustable clutch for very special requirements has been designed:For large-displacement enginesFor heavy or high traction cars (Losi, HPI)For modified performance enginesFor the demanding off-road useRapid wear of a clutch is a sign of constant slipping, even beyond engagement speed. In this case, the clutch does not transfer the applied torque.This is where the Big ScaleEXTREME sets a new standard.The new design of the "Extreme" prevents the centrifugal forces of clutch springs or lever side of the clutch shoes from counteracting the centrifugal force of the friction pad side even after engagement.As a result this clutch can transfer lots of power with minimal wear.The new design ensures that the centrifugal forces are transferred in full to the clutch lining. Precise engagement and disengagement even under high loads and inside of closed clutch bell carriers means no problem for this clutch.The clutch can be easily adjusted to the engagement speed through three set screws without clutch bell removal, so you can match the characteristics of your engine.The special clutch lining of the Big Scale-EXTREME is particularly wear-resistant and - especially in combination with a high-quality nitrited clutch bell (), guarantees for an exceptionally long service life! Contrary to the "Cross" or "Race" version there's no need to uninstall the clutch from the engine for maintenance. All parts are easily accessible from the front after removing the front plate.Please see the specifications tab for further information and handling advices!The regular price of the Big Scale-EXTREME is EUR 139.90
