Product Details

The Rotomaster New Turbocharger Service Kit line is built for turbochargers that need wear-item replacement rather than a full assembly swap. This kit is focused on the parts commonly replaced during remanufacturing, including journal bearings, thrust bearing, flinger, collar, piston rings, O-rings, spacer, retaining ring, and bolts. For owners and technicians servicing a turbocharger on a Chevrolet Silverado 2500 HD or GMC Sierra 3500, A1660306N provides a direct-fit repair solution that keeps the original housings in service when they remain structurally sound.

This part cross-references N166306K for the same application.

What It Helps Address

• Turbocharger wear from aging journal bearings and thrust components
• Oil leakage at seals and piston ring areas
• Loss of turbo efficiency caused by worn service parts
• Need to rebuild a turbocharger without replacing the complete assembly
• Repair planning for select Chevrolet Express, Silverado, GMC Savana, and Sierra applications

Installation Notes and Tips

Confirm that the turbocharger has no internal damage before rebuilding with this service kit. Inspect the center, compressor, and turbine housings for scoring, cracks, or heat damage before reuse. Follow the turbocharger manufacturer’s remanufacturing procedures, clean all mating surfaces thoroughly, and verify oil supply and return conditions before returning the vehicle to service. This kit is specific to the listed applications and is not universal.

Quality Assurance

Rotomaster supplies O.E.-grade, direct-fit components for a service-focused turbocharger rebuild. The kit is packaged in a transparent plastic case for parts organization and inspection before installation.
