Action Clutch ACR-0491-5 Stage 3 MIBA Ceramic Sprung Clutch Kit 2002-2006 Acura

Vehicle Fitment

• 2002-2006 Acura RSX (base, non-Type-S) - 2.0L DOHC (K20A3), 5-speed manual transmission

Fitment Notes

• Fits the 5-speed base RSX only - for the 6-speed RSX Type-S (K20A2), see ACR-0491
• Stage 3 ceramic-based kits are engineered for low-to-mild horsepower vehicles with heavy-duty street use and occasional track/drag/drift applications - not recommended as a daily driver clutch on stock or lightly modified cars
• Clutch chatter is normal and expected with MIBA ceramic discs - it minimizes after proper break-in is completed
• Break-in required: 500 street miles, RPMs under 4,500, no more than half throttle, no boost (if applicable) - break-in must be completed to retain warranty and maximize longevity
• Holding capacity increase is rated in crank torque, not wheel torque

Features

• 170% increased holding capacity over the factory clutch kit
• Sprung MIBA Ceramic disc available in 4-puck or 6-puck configuration - the 4-puck delivers more aggressive engagement; the 6-puck offers slightly smoother take-up
• Sprung hub design provides moderate dampening for improved streetability compared to a solid (unsprung) disc
• Single diaphragm heavy-duty pressure plate with reinforced drive straps for increased durability under repeated high-load engagement
• Rapid heat dissipation from the ceramic friction material maintains holding capacity under sustained performance driving
• Patented fully enclosed spring retainers prevent spring ejection - eliminating a common failure mode that can cause catastrophic transmission or engine damage
• Ductile iron friction plate on all clutch covers
• 4-stage, heat-treated diaphragm spring for consistent clamping force across the RPM range
• 100% dynamically spin balanced to within 0.25 oz-in for smooth high-RPM operation
• American-grade rivets throughout
• SFI Spec 1.1 certified
• Every kit quality checked and signed off by a lead Action Clutch engineer before release

Product Description

The Action Clutch ACR-0491-5 is a Stage 3 (1MS) MIBA ceramic sprung clutch kit engineered for 2002-2006 Acura RSX base models equipped with the K20A3 engine and 5-speed manual transmission. Delivering 170% increased holding capacity over the factory clutch (rated at crank torque), it is built for enthusiasts who demand heavy-duty street performance and occasional drag, road, or drift racing applications. The sprung ceramic disc provides the aggressive engagement and rapid heat dissipation characteristic of ceramic clutches, while the sprung hub design keeps it more streetable than a solid disc setup.

Action Clutch's patented fully enclosed spring retainers are a critical differentiator - they prevent spring ejection that can cause catastrophic engine and transmission damage, a known failure point on competing designs. The pressure plate features reinforced drive straps, a 4-stage heat-treated diaphragm spring, and a ductile iron friction surface, with every assembly 100% dynamically balanced and quality-checked by an Action Clutch engineer before shipping. Note that some clutch chatter is normal with ceramic discs and will minimize after the 500-mile break-in period is completed.
