93313891 Wave-Contour Cast Brake Wheel Cylinder

Product Overview
93313891 is a cast brake wheel cylinder with a wave-contour housing profile. The supplied product data identifies OE 93313891 and lists Chevrolet as the application. Because the available vehicle information is broad rather than model-specific, the OE number should be treated as the main purchasing reference for this item.
The wave-contour casting gives the product a recognizable appearance that can support sample comparison and SKU identification, but it should be used only as a secondary check.

Core Functions
Receives hydraulic pressure from the drum-brake system.
Converts hydraulic pressure into wheel-cylinder piston movement.
Helps apply the brake shoes to the brake drum.
Provides an aftermarket replacement option for the supplied OE reference.
Supports visual product identification through its cast wave-contour housing.

Purchasing Motivation
This model is suitable for buyers who need an OE-number-based Chevrolet brake component but have limited vehicle application information in the current catalog. For distributors, the OE number can be used as the central record while additional fitment details are confirmed before listing or bulk purchase.

Customer Pain Points Solved
Limited application detail: The supplied data identifies Chevrolet but does not provide a detailed model and year list. Keeping the application description conservative avoids unsupported fitment claims.
Product recognition: The wave-contour housing offers a visible feature for sample comparison, while OE 93313891 remains the primary reference.
Catalog accuracy: Buyers can leave additional vehicle, market or cross-reference fields open for manual verification instead of filling them with estimated information.

OEM/ODM Support
OEM/ODM requests can be evaluated from the OE number, sample, drawing, packaging requirement, label specification and target quantity. MOQ, tooling, lead time and other commercial details require project confirmation.
