Luk LFW426 Clutch Flywheel

LuK LFW426 Clutch Flywheel Overview

The LuK LFW426 clutch flywheel is a direct-fit replacement for select Mitsubishi applications, including Outlander Sport, RVR, and Lancer models. It provides the smooth, flat friction surface needed for consistent clutch engagement and reliable transmission operation.

Key Features

• OE-specification clutch flywheel engineered for proper clutch contact and smooth operation
• New flywheel construction, never remanufactured
• Includes ring gear and dowel pins as manufactured components
• 23.6 in. flywheel diameter for the listed applications
• 110-tooth ring gear design
• Flywheel cup depth/step height: -0.26 in. (-6.6 mm)
• Flywheel inner diameter: 15.15 in. (5.965 in.)

Detailed Description

When replacing the clutch on a Mitsubishi Outlander Sport, Mitsubishi RVR, or Mitsubishi Lancer, the flywheel condition is critical to clutch performance. The LuK LFW426 is built to OE specifications so the clutch assembly has the flat, even surface it needs for proper engagement and release. Its 23.6-inch diameter, 110 teeth, and specified step height help maintain the correct geometry for the listed vehicles. This part number, LFW426, is a practical choice when replacing a worn flywheel instead of resurfacing an existing unit.

This part cross-references ACI 88426 for the same application.

What It Helps Address

• Clutch chatter caused by an uneven flywheel surface
• Judder or shudder during takeoff
• Poor clutch engagement from heat-checked or worn friction surfaces
• Noise or drivability issues related to a damaged ring gear
• Incorrect clutch geometry after flywheel wear

Installation Notes and Tips

Inspect the clutch disc, pressure plate, and release components before installation. Confirm the flywheel step height and diameter match the application requirements before assembly. For Mitsubishi Lancer, Outlander Sport, and RVR clutch service, clean mating surfaces thoroughly and follow the vehicle manufacturer’s torque sequence and specifications during installation of the LFW426.

Quality Assurance

LuK manufactures this flywheel as a new OE-specification component, with engineering and manufacturing aligned to original equipment requirements for fit and function.
