• 12-1/4 inch clutch plate facing outer diameter

Detailed Description

Built around LuK’s OE development approach, part number 05-178 is specified for heavy-duty Dodge Ram truck applications where clutch engagement, pedal feel, and drivetrain compatibility matter. The kit is listed for 1998-2003 Dodge Ram 2500 and 1998-2005 Dodge Ram 3500, with flywheel included and a required flywheel match to LFW301 or LFW302. This makes it a focused choice for Ram 2500 clutch replacement and Ram 3500 clutch service when the original clutch system needs to be restored to factory-style operation.

LuK RepSet components are engineered around the vehicle application, and this kit reflects that approach with matched clutch hardware, release bearing, pilot components, and spline lubricant support. The 10-spline disc and 10 disc springs align with the listed drivetrain specifications for these Dodge Ram diesel truck platforms.

Common Problems This Kit Addresses

• Clutch slip under load during towing or hauling
• Hard or inconsistent clutch engagement
• Release bearing noise or wear-related chatter
• Difficulty shifting caused by clutch wear
• Flywheel and clutch component mismatch during service
