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. \u003cbr\u003eMod-Twin 225 HD Sprung Race \u003cbr\u003ePredictable aggressive engagement, light pedal effort, quick shifting, possible start-off judder with OE to mild transmission gear noise; Forged Aluminum Cover, Mono-drive hub, exclusive diaphragm, premium friction materials, and hardened wear points ensure this long-life twin performs and survives under the most demanding conditions; Delivers maximum performance and high heat tolerance by combining robust design, strategic features, choice materials, and close tolerances; Drag, Road, or Rally Racing; Applying tactical engineering to the Mod-Twin, ACT presents unique solutions to common tradeoffs found on twin disc clutches, resulting in an ultra-durable, customer serviceable, long-lasting clutch with very high torque capacity. All are 100% clamp load tested, balanced and SFI certified\u003c\/p\u003e","brand":"ACT","offers":[{"title":"Default Title","offer_id":45669254365347,"sku":"T1R-S05","price":2104.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0683\/9336\/9763\/files\/bc01a0841a931f5d51c0e1e2cbf5acc3.jpg?v=1741364231","url":"https:\/\/www.jdmpurist.com\/products\/act-04-20-wrx-sti-mod-twin-hd-race-kit-sprung-mono-drive-hub-torque-cap-895ft-lbs-not-for-street-use","provider":"JDM Purist","version":"1.0","type":"link"}
