The SPOOLOGIC Turbo Step Gap Oil Seal Kit SL-210-124 is a complete oil seal service pack for the genuine OEM HE300VG turbocharger on 2013-2018 6.7L Cummins applications. Built to OE specifications — the same seal rings SPOOLOGIC uses when building a new turbo on our SL-100 line. Includes new compressor-side and turbine-side step gap piston-ring style seal rings — the two most common oil-control failure points on this CHRA. Ships as a seal-only pack for shops and DIY builders who are servicing a turbo that has developed oil leaks past the shaft seals but still has serviceable bearings and rotating hardware. If bearings, shaft, or thrust hardware also need replacement, order the full SPOOLOGIC Turbo Rebuild Kit for this platform instead.
