Detailed Description

LuK 15-031 is engineered as a complete clutch service solution for covered Subaru manual-transmission vehicles.

Installation Notes and Tips

Verify transmission and clutch specifications before installation, including the 24-spline input configuration and the 35 mm release bearing I.D. noted for covered Subaru applications. The kit includes the bearing retainer repair sleeve and matching release bearing for the listed fitments, so confirm the existing transmission condition and mating surfaces during service. For best results, inspect the flywheel, pilot area, and hydraulic or cable release system before reassembly.
