The ACT 91621 Twin Disc HD Street Clutch Kit is engineered for high-performance street driving and racing applications. Featuring a twin disc design, this kit provides twice the surface area for improved wear characteristics, higher heat capacity, and extended longevity compared to single disc setups. The proprietary Positive Lift Floater System ensures quiet operation without floater rattles or posts to wear, enhancing overall durability and performance. Each component undergoes an exclusive four-stage heat-treating process on all diaphragms, ensuring maximum strength and reliability under demanding conditions.
Constructed with premium organic friction materials containing high copper content, the performance street rigid-hub discs offer superior heat transfer and reduced fade, maintaining consistent engagement even during high-RPM operation. The steel-backed lining provides increased burst strength and durability, while the chrome-moly hub is heat-treated for additional toughness. Carefully selected rivet materials and designs contribute to maximum strength, ensuring the clutch can withstand high torque loads. The kit includes a CNC-machined, dynamically balanced flywheel for trouble-free installation, along with a pressure plate, two discs, a floater, and an alignment tool. Some kits may also include a pilot bearing and release bearing, simplifying installation and ensuring proper operation.
This clutch kit delivers light pedal effort with smooth engagement and minimal gear rattle, making it ideal for high horsepower street or race cars. The components are meticulously engineered and assembled to maintain precise balance and performance. Each kit is 100% clamp load tested and dynamically computer balanced to ensure reliability at high RPMs. Backed by ACT’s industry-leading one-year warranty, the Twin Disc HD Street Kit offers excellence in performance and durability for demanding automotive enthusiasts.
