Action Clutch 17-21 Honda Civic Si 1.5L (L15B7) Turbo Stage 2 Clutch Kit (1SC)

STREET/TRACK APPLICATIONS (OCCASIONAL TRACK USE – CIRCUIT / TIME ATTACK / ROAD RACING) The Super Copper Kit brings a new level of performance to the street and track. It’s built with the highest copper content you’ll find in any organic clutch on the market — giving you a better grip than OEM, better heat tolerance, and more consistent performance on and off the track. 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. This 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. Like 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. Every 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.

The Action Clutch ACR-2190 Stage 2 Super Copper Clutch Kit is designed for 2017-2021 Honda Civic Si models equipped with the 1.5L L15B7 turbocharged engine. Built for street driving with occasional circuit, time attack, or road racing use, this performance clutch kit provides increased holding power over the original equipment clutch while maintaining smooth, predictable engagement for daily use. It is well suited for stock, tuned, and basic bolt-on street cars that need improved power capacity without sacrificing drivability.
The Super Copper kit uses a reinforced steel-backed, copper-loaded organic clutch disc paired with a heavy-duty single-diaphragm pressure plate.

Its organic friction material supports controlled engagement, making it easier to modulate in traffic, during launches, and through spirited driving.
Like other Action Clutch sprung kits, the ACR-2190 includes a patented fully enclosed spring retainer system designed to help protect the clutch assembly and surrounding drivetrain components from spring-related failures. Each kit is hand assembled and subjected to multiple quality checks by Action Clutch’s experienced engineering team, providing a carefully inspected performance solution for Honda Civic Si applications.
