Assemble Quarter Master 2/25

12 Installing the new Quarter Master Optimum-SR begins with disassembling the new unit, which is as simple as removing the eight perimeter bolts that hold the billet cover to the lightweight flywheel. With the cover removed, you can see the sealed spring hub—a nice touch.

Quarter Master Floater 3/25

13 The vented and grooved floater plate comes out next. It bolts in place with a “strap drive” to provide quieter operation and reduced noise, vibration, and harshness.

Clutch Disc 4/25

14 Built from “high-grade OE-type material,” the 10.4-inch clutch disc (left) can handle up to 700 hp while still engaging like a stocker. You can see just how much smaller the disc is compared with an LS6 unit (right).

15 Next up is the flywheel, which bolts on to the engine using six provided bolts. It’s much lighter than the stock unit, so sliding it in place was a breeze.

16 With the flywheel bolted down and torqued to spec, Miller dropped the clutch disc in place, followed by the strap-drive floater. Four bolts hold the straps to the flywheel.

17 The billet cover-and-spring assembly goes on last and is held to the flywheel using eight bolts. It’s a shame you have to hide the anodized cover—it just looks so cool!

18a Quarter Master sent us a new slave cylinder to use with the new clutch. We recommend changing yours out "while you're in there," since it's a quick and easy swap (and costs very little compared with pulling out the driveline again).

19 Next step: Put everything back together. Torque tube, transmission, differential assembly, axles, suspension, rear cradle, exhaust parts, shifter, intake manifold—all of it must go back together before you can get back on the road. For AntiVenom, this is the easy part.

20a The new slave cylinder does require changing out a fitting on the master. First, remove the factory fitting, which is held in place by a roll pin, then slide the Quarter Master–supplied fitting in place and reinstall the pin.

Quarter Master Clutch Hydraulic 13/25

21 Finally, it’s time to refill the clutch hydraulic system and do a little bleeding, preferably using Quarter Master Race Clutch Hydraulic Fluid. A little gravity bleed, followed by a pump-and-bleed session, was all it took. And just like that, we were back on the road with a lighter, faster, stronger clutch. vette
