ISR Performance S-Chassis T56 Master Cylinder with Speed Bleeder Kit

An LS and T56 swap in a Nissan 240SX runs into a problem the moment you press the clutch pedal: the factory S-chassis clutch master cylinder is too weak to operate the internal slave on the heavier LS pressure plate. The ISR Performance S-chassis T56 master cylinder kit with speed bleeder fixes that with a Wilwood master cylinder, the correct line and a remote bleeder that makes bleeding the hydraulic throwout bearing a one person job.

Why the upgrade is required

Running an upgraded clutch master cylinder is not optional on an LSX swap. The larger, heavier pressure plate and the internal T56 slave demand more fluid volume and pressure than the stock master can supply, and the result with the factory part is a clutch that will not fully disengage. The ISR kit provides the proper pedal feel for the T56 while bolting to the S13 or S14 firewall.

What sets this kit apart

• A brand new clevis is included, so there is no need to disassemble the factory master cylinder to reuse its rod and clevis end
• The ISR T56 remote speed bleeder uses a compact bleeder block that mounts to an existing spot on the F-body T56, away from heat sources
• The bleeder block is reachable with a wrench or a vacuum bleeder, unlike loose hose and fitting kits that need to be zip tied somewhere
