Product Description
Complete the clutch hydraulics on your older Honda K-swap with the JBtuned K-Swap Hydro Clutch Line Kit, designed specifically for EF Civic, CRX, and DA Integra chassis using a K20 or K24 drivetrain.
This system connects the clutch master cylinder mounted with your hydraulic clutch conversion setup to the K-Series transmission slave cylinder, passing cleanly through the firewall with a stainless-steel bulkhead connection.

Solves the Clutch Hydraulic Problem in an EF / DA K-Swap
A K-Series swap into an EF Civic, CRX, or DA Integra creates a clutch-system problem that does not exist in later factory hydraulic-clutch chassis.
The K-Series transmission uses a hydraulic clutch slave cylinder, so the older chassis must first be equipped with an appropriate hydraulic clutch conversion bracket and master-cylinder setup.
The JBtuned Hydro Clutch Line Kit completes the hydraulic side of that conversion by providing the connection from the newly installed clutch master cylinder all the way to the K-Series transmission slave cylinder.
Instead of piecing together universal hydraulic hoses, adapters, and firewall connections, the system is designed specifically around the EF Civic, CRX, and DA Integra K-swap layout.
Master Cylinder to K-Series Slave Cylinder
The JBtuned system creates the complete hydraulic path between the clutch master cylinder and the slave cylinder on the K-Series transmission.
The line passes through the firewall using a dedicated stainless-steel bulkhead fitting, providing a secure transition between the interior master-cylinder connection and the engine-bay clutch line.
This bulkhead-based layout helps keep the installation clean and organized rather than simply passing an unsupported hydraulic hose through the firewall.
Designed for EF Civic, CRX & DA Integra K-Swaps
This clutch line kit is designed for:
- EF Honda Civic K-swaps
- Honda CRX K-swaps
- DA Acura Integra K-swaps
- K20 engine and transmission combinations
- K24 engine swaps using compatible K-Series manual transmissions
This is an application-specific K-swap hydraulic clutch system rather than a universal clutch hose.
Hydraulic Clutch Conversion Bracket Required
The hydraulic conversion bracket is not included with this kit.
The vehicle must already be equipped with, or being converted to use, a compatible hydraulic clutch master-cylinder mounting system. The JBtuned clutch line connects to the master cylinder installed on that conversion assembly.
This kit supplies the hydraulic plumbing for the conversion; it does not convert the clutch pedal or chassis to hydraulic operation by itself.
Stainless-Steel Firewall Bulkhead
One of the defining features of this system is the stainless-steel bulkhead connection used where the clutch line passes through the firewall.
The bulkhead provides a dedicated mechanical connection point through the chassis so the interior and engine-bay portions of the hydraulic system can connect cleanly at the firewall.
All supplied clutch-line fittings and bulkhead hardware are stainless steel.
Clean K-Swap Routing
The clutch line is designed around the layout created by installing a K-Series drivetrain into the older EF/DA chassis rather than attempting to duplicate an original factory clutch-line path.
The firewall bulkhead establishes a clean transition into the engine bay, while the engine-side line can be routed toward the K-Series transmission with the surrounding mounts, engine, wiring, and other swap components in mind.
This works especially well in K-swapped cars where the fuel system, wiring, cooling system, and other engine-bay plumbing are already being reorganized around the new drivetrain.
What Is Included?
The kit provides the clutch-line plumbing and connection hardware required to connect a compatible hydraulic clutch master-cylinder conversion to the K-Series transmission slave cylinder, including:
- JBtuned hydraulic clutch line assemblies
- Stainless-steel firewall bulkhead fitting
- Stainless-steel connection fittings and hardware
- Stainless-steel transmission-side connection hardware
- Copper sealing washers
What Is Not Included?
- Clutch master cylinder
- Clutch slave cylinder
- Hydraulic clutch conversion bracket / master-cylinder mounting assembly
- Clutch pedal conversion hardware
- Transmission or other K-swap components
This product supplies the hydraulic clutch line system only.
Part of the JBtuned EF / DA K-Swap System
The clutch line complements the JBtuned EF Civic / CRX & DA Integra K-Swap Fuel Line Kit, which addresses the fuel-system changes required when installing the same K-Series drivetrain into these older chassis.
The two systems solve separate parts of the conversion: the fuel kit adapts the chassis fuel system to the K-Series engine, while the hydro clutch line connects the converted chassis clutch hydraulics to the K-Series transmission.
Installation Notes
Install the firewall bulkhead and hydraulic conversion components securely before final clutch-line routing.
Route the engine-bay portion of the line with adequate clearance from exhaust components, moving parts, sharp edges, drivetrain movement, and other potential sources of heat or abrasion.
After installation, properly bleed the clutch hydraulic system and inspect all connections for leaks before operating the vehicle.
Verify that your hydraulic conversion bracket, master cylinder, and K-Series transmission configuration are compatible before ordering.
