Xcalliber has taken an innovative approach to solving a major issue with the 10L1000 Allison® transmission.
The F clutch drum is prone to failure along the interior center splines under both stock and performance applications.
To address this, Xcalliber has designed and manufactured a splined steel insert that fortifies the center spline of the F Clutch Drum. This steel insert allows the factory drum to be upgraded without requiring changes to any other transmission components.
This modification delivers lasting durability, even under extreme performance applications.
