Spec Hydraulic Upgrade Slave & Master Assembly - Toyota 1JZ/2JZ to R154

If you're swapping a 1JZ or 2JZ engine into a chassis and pairing it with the R154 transmission, getting the clutch hydraulics sorted is a critical step. This assembly from SPEC combines a new master cylinder and slave cylinder specifically designed to make that connection work smoothly. It's built to handle the demands of a performance clutch setup, ensuring you get consistent engagement and reliable operation.

This kit is a well-built unit, featuring a master cylinder that's matched to the slave cylinder for optimal fluid displacement and pedal feel.

This integrated approach helps you achieve a solid, dependable clutch system for your swapped vehicle.
