Hybrid Racing K-Series Clutch Lines

Hybrid Racing offers K-Series clutch lines for a variety of applications, including select Honda© and Acura© models from 1992 and up. These replacement lines are pressure-tested and pre-assembled utilizing a -3 AN PTFE hose encased in a braided stainless steel line. When performing a K-Series swap, you need to connect your clutch slave cylinder and master cylinder together. The stock clutch line on most K-swapped cars will not mate up to the slave cylinder on the K-Series' transmission. Hybrid Racing K-Series clutch line conversions allow the motion from the clutch pedal to be transferred to the clutch fork. The OEM line is too short and the fittings are not the correct size; they're not designed to work with the K-Series slave cylinder. Notes: * Pre-bent for easy installation * Vinyl covers protect components from abrasion * PRFE liner is compatible with all clutch fluids

Hybrid Racing K-Swap Clutch Release Systems

Hybrid Racing K-Swap clutch release system upgrades help to eliminate grinds during hard shifts and improve the feel of gear changes. Factory clutch master cylinders in newer cars are known to be rather unreliable, and because of their poor design and quality, they can lead to premature failures of critical parts throughout the drivetrain. High rpm grinds are mostly attributed to the OE master cylinder's inability to transfer fluid effectively to the slave cylinder, thus causing grinding and rasping of the gears and synchro since the clutch disc hasn't fully disengaged. Upgrading the clutch master cylinder and clutch line to Hybrid Racing K-Swap clutch release systems changes the system to an older, more direct, and efficient system. This improvement allows the driver to feel a more consistent and direct clutch pedal which also improves shifting at high rpms. These kits are intended to replace all of the clutch release components which will give you the most direct and reliable clutch pedal feel. Features and kit contents: * Genuine Honda® parts--not reproductions * OEM Nissin EM1 clutch master cylinder * Stainless steel braided clutch line * Banjo fittings with washers * OEM NISSIN slave cylinder (non-dampened)
