We call them awesome, plain and simple. This is the best 11" unit you can get for the LSx market! How does a holding capacity of 950rwhp/tq sound?

Monster takes a little over 3500 lbs of plate load and mixes it with their sintered iron friction material to bring you a clutch that can take a tremendous amount of abuse! The 11" series is Monster's lighter weight option clutch that will hold the power and abuse. These units fit perfectly in all aftermarket bellhousings, including the Quicktime, and are great for someone looking to make a ton of power while keeping the pedal effort down. Keep in mind that there are some trade offs for the smaller diameter. This unit will chatter on occasion due to the reduced diameter, the pedal effort on stock hydraulics is 8% stiffer than stock, and like our other clutches you will find the weak links in the drivetrain! Don't let the warnings fool you though as we've got numerous units on the street being daily driven without issue, if you don't mind some chatter then look no further!

This clutch is rated at 950rwhp/tq. It is designed to take a tremendous amount of abuse in a racing or motorsport setting; we do not recommend this unit for prolonged street use due to its aggressive nature. The sintered iron material has a superior coefficient of friction and will take just about anything you can throw at it. This clutch should be used aggressively, period.

Basic Package includes the following:

  • 11" pressure plate
  • 11" sintered iron 6 puck clutch disc
  • 28LB SFI certified billet steel flywheel (or an 18LB SFI certified lightweight flywheel for an additional fee, your choice)
  • Pilot bearing
  • Release bearing (unless it's the C6 package)
  • Alignment tool

Option Guide: Basic or Premium Package?

Choose the premium package to include a new GM (AP) Slave Cylinder, which we suggest replacing during every clutch install.  If you do not see a slave cylinder listed for your vehicle in our options menu, the kit is available in Basic Package only for that vehicle. CTS-V applications requires the CTS-V specific slave and please specify that you've got a CTS-V during checkout. Other manufacturer's spacers will not work with Monster Clutches.

Option Guide: Flywheel Type
All Monster Clutches come standard with a 28lb (stock weight) flywheel that is SFI Certified and Billet Steel. If you've got a road-race or autocross application, you may be interested in the optional 18LB Lightweight Billet flywheel that will allow RPMs to come up a little quicker, especially handy when coming off of a turn.  Keep in mind that this lightweight flywheel will let RPMs come down quicker as well, so it will require some driving style changes.  For a street car or drag race car, we always suggest sticking with the 28lb flywheel.

Option Guide: Flywheel & Pressure Plate Bolts
Your factory stock GM Flywheel & Pressure Plate Bolts are not torque-to-yield, so if you're on a budget, you can certainly reuse them.  If you'd like to replace them for good measure, GM replacements are available during checkout.  We've also got ARP bolts available during checkout if you'd like to upgrade the bolts rather than replace them.
