ACT HD/Race Rigid 4 Pad Kit Honda | Accura 1990-2002 - HA3-HDR4

ACT HA3-HDR4 Heavy Duty/Race Rigid 4 Pad Clutch Kit

If you're looking to elevate your shifting experience, the ACT HA3-HDR4 Heavy Duty/Race Rigid 4 Pad Clutch Kit is a compelling choice for performance-driven Acura CL (1997-1999), Honda Accord (1990-2002), and Honda Prelude (1992-2001) owners. This kit features ACT's renowned Heavy Duty pressure plate, designed to handle the demands of spirited driving and track days alike.

Performance-Driven Design

The heart of the HA3-HDR4 kit is its exclusive diaphragm design, which increases clamp load while reducing deflection. This means you get a clutch that not only lasts longer but also provides a more consistent feel during shifts. Each diaphragm undergoes a meticulous four-stage heat-treating process, ensuring that you're getting top-notch performance every time you hit the pedal.

Precision Engineering

ACT's pressure plates are built with precision cover stampings, adding rigidity and consistency to your setup. Coupled with the 4-pad rigid race discs made from high-quality ceramic friction materials, this clutch kit is engineered for those who demand the best. The chrome-moly hub is heat-treated for added strength and durability, giving you confidence in your setup whether you're on the street or the track.

Quick Shifts and Aggressive Engagement

One of the standout features of the HA3-HDR4 is its lightweight, rigid design, which allows for quicker shifts and smooth operation. While the engagement is notably harsher—ideal for racing enthusiasts—this setup means you can expect faster gear changes when it matters most. This clutch is particularly well-suited for smaller disc sizes found in compact engines, making it a perfect match for your performance build.
