Sonnax 54701-03K Bi-Metal Thrust Washer & Shim Kit GM TH180 TH180C 3L30 4L30-E

The Sonnax 54701-03K bi-metal thrust washer and shim kit provides a superior replacement for the factory plastic 3-tab thrust washers in GM TH180, TH180C (3L30), and 4L30-E automatic transmissions. The OE plastic washers are prone to breakage and melting under normal operating conditions, leading to transmission failure and costly repairs.

Key Features:

• Steel tabs eliminate breakage common with OE plastic washers
• Bronze thrust surface resists melting and provides superior durability
• Includes shims for precise endplay adjustment in .010" increments
• Can be stacked to cover build heights from .075" through .125"
• Replaces washers in both pump and center support locations
• Contains enough parts for both pump and stator support locations
• Allows for rebuilding units after pump resurfacing

This complete kit provides the flexibility and durability needed for professional transmission rebuilds, offering superior performance over factory plastic components. Note: This kit is designed for tab-type washers only and cannot replace late-style no-tab thrust washers.
