Product Description

The Action Clutch ACR-3421 is a Stage 3 (1MS) clutch kit built for the 2022 Honda Civic Si 1.5L turbo, bundled with Action Clutch's own chromoly flywheel for a complete drivetrain upgrade in one package. It's designed to withstand demanding conditions well beyond a stock or lightly modified setup, using a sprung MIBA ceramic disc and reinforced drive straps for peak performance and extreme durability.

The ceramic disc delivers quicker engagement than an organic or Kevlar kit, though some clutch chatter is normal and will minimize once properly broken in. All Action Clutch components are computer spin balanced to within 0.25 oz-in for smooth operation across the RPM range, and the kit uses fully enclosed spring retainers to prevent the catastrophic spring pop-out failures possible with some competitor designs. Every kit is quality-checked and signed off by an engineer before shipping.
