Why this specific length and design matter

Tips for installation and care

For best results, verify the cable length matches the original hardware before installation and follow the Corvette’s factory mounting points. Handle the cables with care to avoid kinks, and inspect surrounding guides and pulleys for wear, replacing any frayed components to preserve proper tension.
