Every part in this kit is built to OEM specifications and pre-tested for fitment and balance. This is a complete, ready-to-install package — no sourcing individual components, no mismatched tolerances, no waiting on backorders. Built for the Holset HY35W on 5.9L 24v Cummins applications.

Common Holset HY35W Failure Symptoms

If your 5.9L 24v Cummins turbo is showing any of these symptoms, a full rebuild is recommended:

• Wastegate actuator drift or stuck operation — overboost or underboost, inconsistent boost between runs
• Excessive shaft play or oil seal leakage — blue smoke at idle, oil residue in the intercooler piping, end-play beyond OEM tolerance
• Bearing failure — whining, grinding, or whistling that scales with RPM
• Loss of boost and reduced power — turbo not holding rated boost, sluggish acceleration, excess EGT

Each SPOOLOGIC advanced kit bundles the SL-210 base rebuild kit with the additional wear and upgrade components that fail or get replaced at rebuild time. Buying the kit costs less than sourcing the parts separately and guarantees every part matches the Holset HY35W platform.
