ACT Mod Twin Heavy Duty Sprung Street Clutch For Subaru STI (2004-2021)

Subaru STI Mod Twin HD Clutch Kit (Sprung Hub / Organic Discs) by ACT

T1S-S05 Mod twin street kit offers twice the number of disc surfaces for better wear, heat capacity and long life compared to single disc kits. These kits use a proprietary Positive Lift Floater System design, which results in quiet operation with no floater rattle and no posts to wear. ACT twin disc kits endure an exclusive four-stage, heat-treating process on all diaphragms. The ACT twin disc kits features the ability to adjust for disc wear and provides equal disengagement for discs.

The Performance street rigid-hub discs feature premium organic materials with high copper content for better heat transfer and steel-backed lining for greater burst strength and durability. The chrome-moly hub is heat-treated for strength and durability. Rivet design and materials are carefully selected for maximum strength. All ACT twin disc kits include a CNC-machined and dynamically balanced flywheel to ensure trouble-free installation and operation. ACT twin disc kits include a pressure plate, two discs, a floater, flywheel and alignment tool. Some kits may include a pilot bearing and release bearing.
