JBtuned Honda Civic / Integra Full Tucked Clutch Line - Half-Radiator Applications

Product Description

For builders who want the clutch hydraulics to virtually disappear from the engine bay, the JBtuned Full Tucked Clutch Line takes a completely different approach to master-to-slave routing.

Instead of crossing through the engine bay like a conventional replacement clutch line, this system intentionally takes the long route around the outside perimeter of the engine bay so the majority of the hydraulic line remains hidden from view.

The result is a true master-to-slave clutch line designed specifically for clean, tucked, shaved, and highly detailed Honda engine bays.

A True Tucked Clutch Line

This line exists for one reason: to remove visible clutch plumbing from the engine bay.

The standard JBtuned full clutch line already simplifies the factory hydraulic system with a cleaner master-to-slave layout. This tucked version goes considerably farther.

From the clutch master cylinder, the line is routed into the fender area and around the outside perimeter of the engine bay before returning toward the transmission and slave cylinder.

The line is intentionally much longer than a conventional clutch line because that additional routing distance is what allows the hydraulic plumbing to remain largely hidden.

Complete Master-to-Slave Replacement

This is a complete clutch hydraulic line from the master cylinder to the slave cylinder.

The original clutch hard line and factory rubber hose sections are no longer required, allowing the visible factory hydraulic plumbing to be removed from the engine bay.

This is not simply a braided replacement for one section of the original system. It replaces the complete hydraulic path while relocating that path away from the normal visible engine-bay routing.

Half-Size or Split-Style Radiator Required

A half-size or compatible split-style radiator configuration is required for the intended tucked routing.

The line needs the open routing space created by the reduced-width radiator layout in order to travel around the outside of the engine bay and return toward the transmission.

Because of this, fitment is determined primarily by the radiator layout and available routing space rather than simply by whether the vehicle uses a D-Series or B-Series engine.

For example, an Integra retaining a full-width factory-style radiator does not provide the required routing space for this tucked configuration.

If your vehicle retains a full-width radiator, use the standard JBtuned full clutch line instead.

Why Is the Line So Long?

The additional line length is deliberate.

A conventional master-to-slave clutch line takes the shortest practical route across or through the engine bay. That works well functionally, but part of the hydraulic line remains visible.

The JBtuned tucked line does the opposite: it takes the long way around so the line can travel through the fender/perimeter area and stay out of sight for most of its path.

For a normal engine bay, that extra routing may be unnecessary. For a shaved, tucked, or highly detailed engine bay where visible plumbing is intentionally minimized, that routing is the entire purpose of the product.

Built for Clean and Tucked Engine Bays

This line is intended for builders who are already making deliberate choices about what remains visible under the hood.

Fuel lines, wiring, brake plumbing, cooling components, and other systems are often relocated or simplified in a fully tucked engine bay. Leaving the clutch hydraulic line running prominently across the engine compartment can work against that finished appearance.

The tucked clutch line moves that hydraulic connection away from the visual center of the engine bay so the engine, fabrication, and overall layout remain the focus.

PTFE Line with Stainless-Steel Hardware

The clutch line uses a PTFE inner liner surrounded by stainless-steel braided reinforcement with a black protective outer coating.

The assembly uses permanently crimped stainless-steel fittings and adapters, with black Mil-Spec resistant heat shrink protecting the hose-end transitions.

Copper sealing washers are supplied where required for the hydraulic connections.

Protect the Line During Tucked Routing

Because the hydraulic line travels through areas outside the normal engine-bay routing path, care should be taken anywhere the line passes near sheet metal, openings, brackets, or other potential abrasion points.

Use appropriate grommets, edge protection, or other abrasion protection anywhere the line could contact a sharp or unfinished edge.

Final routing should also maintain adequate clearance from moving components and high-heat areas.

Optional Installed Lava Sleeve

An optional Lava Sleeve heat-protection section is available for installations where part of the tucked routing passes near a header, turbocharger, turbo manifold, or another significant heat source.

The Lava Sleeve must be selected when ordering. It is installed onto the clutch line while JBtuned manufactures the assembly and cannot be added afterward without rebuilding the line.

If your planned routing will require additional heat protection, select the Lava Sleeve option before the line is manufactured.

Standard Full Line or Tucked Line?

Choose the standard JBtuned Full Clutch Line if your priority is eliminating the factory multi-piece clutch plumbing with a cleaner, more direct master-to-slave replacement.

Choose this Full Tucked Clutch Line if your priority is hiding as much of the clutch hydraulic plumbing as possible and your radiator configuration provides the space required for the perimeter routing.

The tucked version is not intended to be the simplest or shortest routing solution. Its purpose is achieving the cleanest possible visual result.

Important Fitment Information

Verify your radiator configuration before ordering. The intended tucked routing requires a half-size or compatible split-style radiator layout with sufficient space for the line to return into the engine bay toward the transmission.

Do not determine compatibility solely by engine family or chassis designation. Radiator layout, available routing space, master/slave configuration, and the individual vehicle build all affect installation.

After installation, properly bleed the clutch hydraulic system and inspect all connections and protected routing points before operating the vehicle.
