Product Description
ACT 04-20 WRX STI Mod Twin HD Race Kit Sprung Mono-Drive Hub Torque Cap 895ft/lbs
Not For Street Use
Subaru STI Mod Twin HD Clutch Kit (Sprung Hub / 6-Pad Discs) by ACT
This Mod-Twin 225 HD Sprung Race Kit performs aggressive launches and smoother shifting in high powered AWDs by combining twice the ceramic friction surfaces with an ultra-durable Mono-Drive sprung hub assembly in a completely modular design. Each diaphragm spring endures an exclusive four-stage heat treating process providing a consistent light pedal feel. Puck-style Friction Plates with high quality ceramic friction materials deliver high friction coefficient, superior heat capacity, and long clutch life. These Friction Plates uniformly transfer torque to a Mono-Drive sprung hub assembly which extends input shaft life and reduces driveline shock from torsional vibration.
This kit includes a CNC-machined and dynamically balanced flywheel, pressure plate cover, diaphragm spring, face, puck-style ceramic friction plates, sprung Mono-Drive hub assembly, floater, patented Monoloc Collar, release bearing, alignment tool and pilot bearing (if needed). Mod-Twin clutches are fully rebuildable and most components can be ordered separately.
