Quarter Master® Optimum-SR™ 10.4" Single-Disc LS Clutch Kits

Share

Lake Zurich, IL – Quarter Master® has released a single-disc LS clutch kit, a lower-cost alternative to its two-disc setup. The one-disc option features less rotating mass than stock, while delivering stock pedal feel and chatter-free operation.

Those looking for a true racing clutch with factory driving characteristics will find Quarter Master® Optimum-SR™ 10.4" Single-Disc LS Clutch Kits ideal. The kit’s lighter weight (50% lighter than the stock assembly) creates a reduced MOI, allowing the engine to rev and de-rev more quickly than a stock OE unit. All these features knock seconds off the stopwatch, while delivering a stock pedal feel and chatter-free operation. Holding up to 500 ft./lbs. of torque and 700 horsepower, the kit comes with the clutch, flywheel, release bearing and release bearing adapter. Legal for use in the Pirelli World Challenge and Continental Tire Series, the clutch’s race-capable design can also easily be used for street driving. The single-disc clutch boasts billet construction and is 100% re-buildable. The unit is constructed with proprietary spring technology and is compatible with OE-type hydraulic bearings or the Quarter Master® Tri-Lite II hydraulic systems. With exquisite craftsmanship and design, the Quarter Master® Optimum-SR™ 10.4" Single-Disc LS Clutch Kits are for the enthusiast that seeks the best engineering combined with the highest standards in quality. The kit is available for slightly modified ’97-’04 Corvette (C5), ’05-’13 Corvette (C6), ’06-’13 Corvette Z06, and ’08-’09 Pontiac G8 GT/GXP applications.
