The GKTECH braided clutch lines are a direct replacement of the factory lines and are stronger than the factory rubber lines which are prone to breaking but they also eliminate the spongy feel of the clutch. You now have the choice to choose between replacing the OEM clutch line damper system by selecting the damper delete option, which is also a good choice when doing an Auto to Manual transmission conversion. This line runs direct from the master cylinder to the slave. Alternatively you can choose to retain the OEM damper system and just replace the shorter clutch line only, meaning it will run from the OEM damper system to the slave cylinder. The lines are assembled by us in-house in Australia using quality UK made stainless steel fittings, stainless steel braided line with a Teflon inner tube and PVC outer for protection, which comply with all ADR, DOT and TUV specifications. Vehicle Compatibility: - Nissan S13 Silvia - Nissan 180sx - Nissan S14 Silvia - Nissan S15 Silvia NOTE: Will not fit LHD applications.
