Detailed Description

The LuK LFW405 is a replacement clutch flywheel made for vehicles that require a precise, flat mating surface during clutch installation. It is built to OE dimensions and manufactured as a new part, making it a straightforward choice when servicing the clutch system on a Dodge Dakota, Dodge Ram 1500, or Mitsubishi Raider.

Compatible With 2001-2009 Dodge Dakota, 2002-2008 Dodge Ram 1500, and 2006-2009 Mitsubishi Raider. The LFW405 supports proper clutch operation by restoring the flywheel surface and maintaining the correct ring gear and dowel pin layout for the application.

Common Issues This Part Can Address

• Uneven or worn clutch contact surface
• Chatter or shudder during clutch engagement
• Vibration caused by flywheel wear or heat spotting
• Difficulty achieving smooth clutch take-up after service
• Need to replace a flywheel instead of resurfacing an old unit

Installation Notes and Tips

Verify engine and transmission application before installation, especially on Dodge Dakota, Dodge Ram 1500, and Mitsubishi Raider models. Inspect the clutch assembly, pilot components, and related wear items during service so the new flywheel can be installed on a clean, flat mating surface. Confirm the 143-tooth ring gear and OE-style dimensions match the original part before final assembly.

Quality Assurance

LuK manufactures this flywheel to OE specifications as a new component, with attention to the ring gear and dowel pins for accurate fitment and dependable clutch service.
