Terrafirma - Dual Mass Flywheel Conversion Kit - TD5

The Terrafirma Dual Mass Flywheel Conversion Kit allows you to replace your factory dual mass flywheel with a solid single-piece alternative. Compatible with Defender 90, 110, and 130 models as well as Discovery 2 vehicles equipped with TD5 engines and manual gearboxes, this conversion kit offers improved reliability for demanding driving conditions. Original equipment dual mass flywheels feature a two-piece design with controlled flex between the crankshaft-mounted section and the clutch engagement surface. This design reduces engine vibration and provides smooth clutch engagement under normal driving. However, aggressive off-road use with larger tyres or modified engines can lead to premature failure, typically accompanied by excessive vibration, rattling noises, and clutch slip. A solid flywheel conversion provides enhanced durability and is the preferred solution for off-road driving and towing applications. This upgrade delivers superior reliability compared to the dual mass design in challenging conditions. For optimal performance, pairing this conversion with a heavy-duty clutch kit is strongly advised, as the increased shock load from solid flywheel engagement requires the enhanced capacity of a performance-rated clutch.
