500+ Support Package

4.8 LS 500+ Support Package.

Use this package to support a harder-running 4.8 LS with the bearings, oiling, valvetrain, and timing parts that commonly matter once the build moves beyond a basic stock refresh.

Package Parts

Reliability parts for a stronger 4.8 LS foundation.

These parts help support oil control, bearing condition, valvetrain stability, and timing reliability. Final sizing should still match the engine condition and machine-shop measurements.

Bearings

King rod and main bearing set

Choose stock size for an uncut crankshaft, or open the undersize options if the crank has been machined. Verify crank journal size before ordering.
