Description

This kit aims to deliver a more precise and crisp pedal feel, ensuring your clutch system is robust enough for demanding driving conditions. Constructed with quality materials, the kit includes a master cylinder featuring a .750" bore. The accompanying components are made from durable materials: billet aluminum for the adapter cap, reservoir cap, and clevis, and stainless steel for the 3AN clutch line. This two-piece line design offers flexibility for different transmission layouts, accommodating both passenger-side (D, B, H engines) and driver-side (K engines) configurations, and also allows for the potential addition of a Flow Control Valve. It's noted that in some applications, slight modification, such as cutting down the pushrod, may be necessary for proper fitment. The kit has been developed by Clutch Masters to offer increased reliability and a wide range of applications, contributing to smoother shifting and serving as a significant upgrade for older vehicles.
