A lot of older Hondas came factory with cable clutch transmissions, which becomes limiting once you start looking at newer hydraulic transmission options for swaps or racing.
This cable to hydro conversion was built to solve that without converting the entire chassis.
The setup mounts inside the cabin and converts the factory cable pedal into a hydraulic master cylinder setup while keeping the engine bay cleaner and simplifying transmission options.
That means access to more transmission combinations, better aftermarket support, and easier clutch options for higher horsepower setups.
Fits multiple 84 to 93 Civic and Integra applications depending on transmission combination.
If you are planning a swap and want to stop being limited by cable transmission options, these are available now on our website.
A lot of people see hood hinges as just another bolt-on part.
What they don’t see is the support side behind the scenes.
Replacement parts.
Updated revisions.
Legacy inventory.
Gas spring coverage.
Adjustable stop systems.
Real-world feedback turning into design changes.
That’s the difference between just selling a product and building a supported ecosystem around it.
Our current hinge line includes:
✔ Adjustable stop system
✔ Updated revisions/refinements
✔ Available replacement parts
✔ 5-year gas spring warranty
✔ Direct support from the people who actually build them
We still do our best to help owners of older/used authentic Hush hinges too, but active support inventory and revisions matter.
That’s part of the value.
Originally developed around the EF chassis, but it did not stop there.
These cable to hydro conversions were built to give older cable clutch Hondas access to modern hydraulic transmissions. That means newer engine swap combinations or better transmission options.
The system mounts inside the cabin and converts the factory cable pedal assembly to accept a hydraulic master cylinder which also keeps the engine bay clean and finished with our custom billet reservoir.
Applications available for LHD 84–93 Civic and Integra
One of those parts that solves a problem many people accepted as normal.

The cam changes the engine.
The cam gear changes where the power happens.
F23 already makes decent low end torque, so the goal here is seeing if this combo wants more top end once the 250 shot goes on.
Built for the chassis that shaped an entire generation.
The DCHH1 was not created because the world needed another hood hinge. It was built because we were tired of watching lightweight and carbon fiber hoods flex, twist, and fold under uneven support from outdated designs. We wanted something cleaner. Stronger. More intentional.
So we built a hinge around the real problem.
Instead of relying on a prop stick or awkward external support systems, the DCHH1 integrates the gas spring directly into the billet hinge itself. The result is smoother operation, equal hood support from side to side, and a cleaner engine bay without sacrificing function.
But the goal was never just appearance.
The integrated adjustable hood stop was designed to help customers running hood spacers reduce the risk of hood-to-windshield contact while giving more control over hood opening angle. Real function for real builds.
Machined from 6061 billet aluminum and designed as a true bolt on solution, the DCHH1 fits both USDM and JDM 1994-2001 Acura Integra and Honda Integra hoods.
Built for the cars we actually love.
Built for the people still building them.
Real problem. Real solution.
Leave the broom stick in the kitchen.
The goal was simple. Support the hood the right way without risking damage to steel or carbon hoods. A lot of hinge setups put uneven load on the hood and that’s how you end up with flex, stress, or worse, a folded hood.
We built these because we needed equal support across the hood on our own cars. Something that actually holds the weight correctly, opens smoothly, and doesn’t fight the chassis or the hood.
The gas spring is integrated directly into the billet hinge so everything works as one system. Cleaner look, controlled movement, and real support where it matters.
We also added an adjustable hood stop so you can run hood spacers with more control and less risk of the hood contacting the windshield. That matters when you start changing geometry and airflow but still want to protect the car.
This is not universal. It’s built specifically for 88 to 91 Civic hatch and CRX because that’s the platform we know and actually build on.
Form and function finally meet in the same place.
EFHH2
At this level a scatter shield becomes part of the build.
A scatter shield surrounds the clutch and flywheel area. If something fails at high rpm it is designed to contain it or at least reduce the damage. It is not there to prevent failure, it is there to control what happens when something lets go.
The direction for this car is around 550hp with a 250 shot which puts it into the 10 second range. Most tracks and NHRA guidelines require a shield once you get into roughly the 11.49 and quicker range, so this is something that has to be addressed before getting there.
This unit is made to bolt directly to the block, but the OEM cast engine brace is being kept, so an extension bracket was made to allow both to work together.
That portion fits as intended. The remaining issue is slave cylinder clearance with the current quick release setup. That will be worked out next.
This replaces the need for a hood prop and keeps the hood evenly supported instead of flopping to one side. It also opens high enough to work on the car or even pull an engine without removing the hood.
This also ends up being an alternative to quick releases. A lot of people think they need to remove the hood, but with the added opening and control, you don’t.
For cars already running quick releases, this gives you a way to actually keep the hood on the car without dealing with a prop or instability.
It’s also adjustable to compensate for hood spacers and works with steel, carbon, or fiberglass hoods.
This is one of those parts that solves multiple problems at once, and ends up cleaning up the bay more than expected.
Current applications.
88–91 Civic / CRX
92–95 Civic
94–01 Integra (JDM front ends included)
96–00 Civic
RHD & LHD supported on all models
Adjustable hood height for hood spacers
This is our 96–00 Civic billet hood hinge with integrated gas spring. Still in progress, aiming for release this summer.
EKHH3 This is our third version. A lot of what changed came from what we saw with the first two.
Fitment was refined, the hood stop was reworked to be more controlled, and the contact area was strengthened. We also widened the footprint and added a gasket to better distribute the load.
This version adds bearing support at the base to arm connection, including a thrust bearing. It now uses two bearings in that area to better handle the load and movement.
A lot of small changes, but they add up over time.
We didn’t set out to make hood hinges.
It started with needing even support. A single prop lets the hood flop to one side.
Then swaps came in, and guys were cutting support just to make engines fit. Remove the prop, and people start figuring out their own ways to hold the hood up.
This solved that.
Then we realized it cleaned up the bay more than expected. One of those things you don’t notice until it’s gone.
From there we added height adjustment, which helps when running hood spacers.
This build didn’t start as something to prove.
Along the way, it turned into that.
Going through it brings things back to what this has always been.
Not about proving who’s better.
Just remembering what got us here.
