Is your clutch pedal sticking to the floor when you drive your car aggressively?  Are you having trouble shifting your car quickly in the upper RPMs?  Are 1st Gear and Reverse hard to engage while the car is sitting still?  You’re not alone!

Thousands of LS1 & LS2 GTO owners have cured issues like these (or avoided them altogether) with our Tick Performance Adjustable Clutch Master Cylinder Kits!

GM did not want to replace transmission and driveline parts under warranty, so they designed a very weak, anemic clutch master cylinder barely capable of moving enough fluid to fully disengage the stock clutch in perfect working order.  With years of wear (and/or an aftermarket clutch that requires more fluid to disengage), the inadequacy of the GM Master Cylinder becomes even more apparent.

Our Tick Performance Adjustable Clutch Master Cylinder Kits are built here in the USA around Tilton 7/8” Bore Cylinders (the same used in NASCAR every Sunday) and are made adjustable so that you can tailor the amount of fluid that your system needs in order to fully disengage ANY clutch, from stock to hardcore race-only clutches.  With our kit installed, you’ll notice:

  • A slightly stiffer (we normally see ~15%), shorter pedal (in most cases) due to the increased cylinder bore
  • A clutch pedal that is easier to modulate with a predictable, constant engagement point
  • Effortless shifts at any RPM (especially high RPM), even when driving extremely aggressively
  • Longer clutch & transmission life as a result of a properly-disengaging clutch
  • Multiple other issues and annoyances fixed, including the infamous “crashed pedal”

Every Tick Performance Adjustable Clutch Master Cylinder Kit ships complete with everything needed to install, including our Unrestricted and Heat-Wrapped Stainless Braided Clutch Hydraulic Line (eliminating the need for the "drill mod"), all necessary hardware, and easy to understand instructions.  Transmission removal is not required for install.  Installation generally takes 90-120 minutes and adjustments can be made at any time without any tools.

Tick Performance Adjustable Clutch Master Cylinder Kits are capable of more fluid flow than any competitor’s offering, and we stand behind them with a LIFETIME Warranty against leakage.  Rest assured that with our kit installed, you'll have the quickest shifting, most reliable kit available under your left foot!

    Nice upgrade!

    Posted by Brian Mc on 1st Aug 2016

    Finally installed the Tick Performance Adjustable Clutch Master Cylinder kit in my '05 GTO. I wasn't happy with the stock set-up for various well known reasons. Okay, I consider my sell pretty handy with a wrench, but this took a little longer than 1.5 - 2 hours to install. No "special" tools are needed, but you should have a well stocked bunch of sockets and various adapters. Its not obvious from the directions, but be sure to take apart the aluminum adapter from the master cylinder! You'll never get it installed otherwise. One thing I had happen and I'm not sure what it was about. After the initial install and adjustment I took the car for a road test. Came home and pulled in the garage and shut her down. Looked under the car and she was spewing fluid pretty good. It didn't drain the system, but gave me a scare. Topped off the reservoir and got under the car after she cooled to see what's up. Nothing obvious. Fittings were tight and bleeder valve was good. Took it back on the road and nothing. Behaved like you want with no leeks. Not sure what that was about. I wanted to suspect the "O" ring, but...so far so good. Pedal is quite a bit down from the stock location like Tick says it will be. Pedal pressure increased but nothing ridiculous. Pedal throw is much shorter with clutch engagement/disengagement almost immediate. So far I'm very happy with the upgrade.
