If you’re looking to upgrade your clutch game, the ACT SB2-HDSS Heavy Duty/Performance Street Sprung Kit is a solid choice. This kit packs a punch with ACT’s most popular heavy-duty pressure plate and street disc. Let me tell you, this isn’t just marketing fluff; it’s built to last and perform. The heavy-duty pressure plate uses a unique diaphragm design that boosts clamp load while minimizing deflection, which means your clutch will last longer and handle the heat better. They even put their diaphragms through a four-stage heat-treating process to ensure they’re up to the task.
The pressure plate is designed with precision cover stampings, giving it that extra rigidity and consistency you want when you're really pushing your ride. And the performance street disc? It’s made from premium organic materials packed with copper for better heat transfer. You’ll appreciate the steel-backed lining too; it adds to the durability and burst strength. Plus, the reduced marcel means you’ll get quicker shifts, which is a must for those spirited drives.
