TeraFlex Jeep JK Brake Master Cylinder with Oversized Bore

We have a brake master cylinder with an oversized bore that has 14% more flow. It is a recommended upgrade to provide a firmer pedal when using our Big Brake kit. This is a great solution to a softer pedal that may appear once you have had the Big Brake Kit. 2007-2008 and 2011 JK's have a greater need and we highly recommend this cylinder for those applications.
Product Details & Specs
Note:    The Heavy Duty Master Cylinder Part # TF4303450 is required for JK model years 2007,2008 and 2011 applications.
Kit fits:    Wrangler JK Unlimited 07+, Wrangler JK 07+
