Backed by a reinforced steel plate and a copper-loaded organic facing, it’s designed to hold more power without giving up smooth street drivability.\nThis kit uses our reinforced steel-backed, copper-loaded organic disc paired with a heavy-duty single diaphragm pressure plate — delivering smooth engagement you can daily drive, and the grip you need when you push it. It’s the ideal setup for stock, tuned street cars and basic bolt-on builds that want more without giving up drivability.\nLike all of our sprung kits, the Super Copper features our patented fully enclosed spring retainer system — protecting you from failures that can cause serious transmission or engine damage, a problem we guarantee you’ll see with other brands.\nEvery kit is hand-assembled and signed off after multiple quality checks by our senior engineering team (50+ years combined experience), making sure you’re getting real, tested performance — not guesswork.\nStage 2 Clutch Kit (1SC) for Honda Civic SI 2017-2021 1.5L (L15B7) Turbo\n\u003cp\u003eThe Action Clutch Stage 2 Super Copper Clutch Kit is designed for street-driven and occasional track-use [17-21 Civic Si] models equipped with the 1.5L L15B7 turbocharged engine.
