TinzerMotor New Items: 11QX46AM and 11QX45AM Window Regulators

TinzerMotor has introduced the 11QX46AM (Left-Hand) and 11QX45AM (Right-Hand) electric window regulators, specifically engineered as premium aftermarket replacements for Mack CHU, CXN, CXU, and GU (Granite) series trucks. These assemblies are designed to restore smooth window operation with enhanced durability compared to standard components.

1. Key Specifications and Compatibility

These models serve as direct "bolt-on" replacements for several OEM part numbers:

· 11QX46AM (LH): Replaces Mack 25080533, 25175116, 84031207, and 82795575.

· 11QX45AM (RH): Replaces Mack 21544322, 25175115, 84031206, and 82795574.

· Application: Optimized for heavy-duty vocational environments, including construction and regional haulage.

2. Performance and Durability Features

The 11QX46AM and 11QX45AM series feature several engineering upgrades to combat the high-vibration environment of commercial trucks:

· High-Torque Motors: Equipped with robust electric motors that maintain consistent speed and prevent overheating during frequent use.

· Reinforced Cable System: The internal steel cables and tensioners are reinforced to resist stretching and snapping, a common failure point in original units.

· Weather Resistance: All electrical connectors and motor housings are sealed to prevent corrosion from moisture and road debris.

3. Installation and Maintenance

Both units are designed for ease of service. They utilize factory-matched mounting points and plug-and-play wiring harnesses, eliminating the need for splicing or door frame drilling. This precision fit reduces installation time to approximately 45–60 minutes per door, significantly lowering vehicle downtime.

Summary

11QX46AM and 11QX45AM provide a cost-effective, high-quality alternative to OEM parts. By focusing on mechanical longevity and precise fitment, these regulators ensure operator safety and comfort in demanding Mack truck applications.
