L3SA UPDATE
If you’re running an original 1988-1991 Honda cable D-series transmission (L3) but want the benefits of a hydraulic clutch system, that’s exactly what our L3SA was designed for.
The L3SA allows a hydraulic clutch system to operate the factory cable-style D-series transmission, eliminating the clutch cable while keeping the original transmission in place.
For many enthusiasts, this means stronger clutch options, more consistent pedal feel, reduced cable failures, and the ability to continue using their existing transmission without converting to a newer hydraulic gearbox.
Recently, while helping a customer with his installation, we identified a situation that wasn’t clearly addressed on the product page.
Most customers purchase our cable-to-hydro conversion and L3SA adapter together. When purchased together, we build the clutch line specifically for that combination, so everything fits correctly right out of the box.
However, some customers purchase the L3SA separately, already have a hydraulic conversion, or are building their own custom setup. In those cases, clutch line routing and reach can vary depending on the chassis and components being used.
To make those installations easier, we’ve added an optional extension adapter.
This extension bridges the gap between the slave cylinder and existing clutch line when additional reach or routing flexibility is needed.
A few important notes:
• The extension adapter is optional
• It is not included with the standard L3SA kit
• Most customers will not need it
• It is intended for custom setups, existing conversions, and situations where components were purchased separately
We’ve updated the product page with additional photos and information to help customers determine whether the extension may be beneficial for their specific setup.
As always, if you’re unsure what combination is right for your project, send us a message with your chassis, transmission, and clutch setup and we’ll help point you in the right direction.
