Stock replacement GM Slave Cylinder & Throwout / Release Bearing for 2004-06 Pontiac GTO, LS1 or LS2 Engine, Part #24264183. Formerly GM #92067762. If you're removing the transmission for any reason, make sure you replace the slave cylinder while you've got everything apart. The weak link in the factory hydraulic setup is the master cylinder, so there is no need to upgrade your slave - just keep it fresh. Now is a great time to upgrade to our Tick Performance Remote SPEEDbleeder Line, as well!
You've got two choices when it comes to replacing the slave cylinder. You can go with this factory GM replacement for GTO (which includes the correct fitting to accept the stock GTO connection elbow) or purchase a 2001+ LS1 F-Body style slave cylinder for less money and swap your fittings off of your original slave onto your new one during the install. The F-Body (Camaro or Firebird) part number is 24264182. Both slave cylinders include throwout bearing, choose whichever works with your budget the best. Both are GM quality - don't trust an aftermarket slave cylinder!
For those of you who no longer have your GTO slave, fitting or elbow, you'll need to purchase this #24264183 slave cylinder (which includes the proper fitting) and the GTO Connection Elbow #92067510, found here.
