Detailed Description

ATP Parts TS-4 flywheel shim is built for drivetrain correction where factory spacing has changed due to machining, crankshaft endplay, or transmission component replacement. In manual transmission service, it restores a machined flywheel to the proper height. In automatic transmission applications, it helps address excess clearance created by engine crankshaft endplay or by installing a rebuilt torque converter or rebuilt front pump. This part cross-references Pioneer Automotive Industries FWS-4 for the same application.

Compatible With Dodge Challenger, Dodge Ram 1500, Dodge Ram 2500, Dodge Ram 3500, Jeep Cherokee, and Mitsubishi Eclipse applications where the listed dimensions match. ATP TS-4 is also referenced for additional Chrysler, Dodge, Jeep, Plymouth, Toyota, and Mitsubishi vehicles across the model years shown in the fitment data.

What It Helps Solve

• Incorrect flywheel height after machining
• Excessive clearance in automatic transmission assemblies
