Detailed Description

LuK 07-225 is a clutch kit for 1988-1994 Ford F-250 and Ford F-350 models with the solid flywheel option and aftermarket turbocharger applications. It is built around a push type diaphragm pressure plate and a large-diameter clutch assembly sized for heavy-duty truck use. The kit is specified with a 12-5/16" clutch disc, 10-spline disc hub, and 1-1/4" input shaft diameter, helping ensure the clutch components match the transmission and flywheel requirements of the listed vehicles. This part cross-references Sachs K70244-01 for the same application. LuK 07-225 is a direct-fit option for Ford F-250 and Ford F-350 clutch service where the original application calls for the included flywheel and related release components.

What It Helps Address

• Clutch slip under load
• Hard or inconsistent clutch engagement
• Release bearing noise or wear
• Shudder during takeoff
• Loss of drivability from worn clutch components

Installation Notes

Verify the vehicle is a 1988-1994 Ford F-250 or Ford F-350 with the solid flywheel option and aftermarket turbocharger application before ordering. Confirm the clutch disc spline count, input shaft diameter, and flywheel setup against the existing drivetrain components. Follow factory service procedures for alignment, torque sequence, and break-in after installation.
