The SPOOLOGIC Turbo Rebuild Kit SL-210-044 is a complete internal-parts service kit for rebuilding a genuine OEM HE300VG variable geometry turbocharger on 2013-2018 6.7L Cummins applications. Built to OE specifications and sized to drop directly into the factory CHRA — the same internal wear parts SPOOLOGIC uses when building a new turbo on our SL-100 line.

Common Failure Symptoms

• Excessive shaft play or wobble in the rotating assembly
• Oil leaking past compressor or turbine seals into the intake or exhaust
• Whining, howling, or grinding noise from the CHRA
• Loss of boost or slow spool-up from worn bearings and seals
• Sticking VGT vanes or unison ring binding from worn bushings

Built to OE Spec

Every wear item that spins, seals, or supports the rotating assembly is included as a new part — extreme duty journal bearings and snap rings, 360° thrust bearing and thrust collars, step gap piston-ring seal rings, VGT unison ring bushings, and the compressor-side hardware and O-rings required to reassemble the cartridge. This is the same internal parts kit used inside every brand new SPOOLOGIC HE300VG turbocharger.

What’s Inside the Kit

• Extreme duty journal bearings and snap rings
