INFO

4.8L LS Valve Spring Set is designed for 2001-2017 Chevy Silverado 2500 HD and supports valvetrain service or a matched camshaft upgrade requiring the stated spring pressure, lift capacity, and installed dimensions. The service scope centers on the stated spring style, installed height, coil-bind clearance, pressure, lift capacity, and package quantity.

During operation, the valve spring closes the valve and maintains contact through the camshaft's operating range. Inspection commonly follows a broken or weak spring, inadequate spring pressure, coil-bind risk, or a camshaft profile requiring matched springs. The same inspection should cover the installed height, retainers, locks, valve seals, rocker geometry, and camshaft lift requirements because wear or damage there can affect the replacement. Follow the application-specific service procedure for lubrication, timing alignment, fastener torque, and initial start-up checks. Install this 4.8L LS Valve Spring Set only in the stated component position and configuration.

Features

  • Returns the valve to its seat and maintains valvetrain control through the operating cycle.
  • Matches the stated spring style, diameter, installed height, and lift capacity.
  • Supports replacement after testing identifies weak, damaged, or unsuitable springs.
  • Keeps spring quantity and valvetrain configuration tied to the listed package.
  • Uses the listed valve spring style configuration: Beehive.
  • Requires installed-height, retainer, seal, and coil-bind clearance checks during assembly.
