High performance rebuild kit to suit K03/K04 turbochargers.

The standard K03/K04 uses a weak thrust bearing and small thrust collar which cannot cope with the increased thrust load at higher boost pressures.

This kit includes a full face 360* thrust bearing and larger collar to displace the increased thrust load which is a must on these turbochargers to ensure reliability at boost levels above 18psi.

The performance rebuild kit includes:

  • Heavy Duty Full Face 360* Thrust Bearing
  • Heavy Duty Thrust Collar
  • Heavy Duty Journal Bearing 
  • Turbine Side Heat Treated Piston Ring
  • Compressor Side Heat Treated Piston Ring 
  • Bearing Retainer
  • Front Seal Plate O-Ring 
  • Heatshield
  • Seal Plate Snap Ring
  • Turbine Side Heat Shield
  • Journal Bearing Retainers
  • Shaft Nut

Care Instructions

Before installation: Engine oil and oil filter must be replaced. Turbo oil-feed line must be removed and thoroughly flushed to ensure there is no debris.
