Semi Truck Mirrors: Complete Replacement & Buying Guide for Every Brand

Mirrors are one of the most critical safety components on any semi truck. Whether you're replacing a damaged mirror after a sideswipe or upgrading from manual to power-heated mirrors, choosing the right aftermarket replacement matters. This guide covers everything you need to know about semi truck mirrors — from types and features to fitment for every major brand.

Types of Semi Truck Mirrors

Semi trucks use several types of mirrors, each serving a specific purpose for safe driving and DOT compliance.

Main West Coast Mirrors

The large rectangular mirrors mounted on both sides of the cab. These are your primary mirrors for lane changes, merging, and general rearward visibility. Available in flat or convex glass, and in chrome or black housing to match your truck's style.

Convex (Wide-Angle) Mirrors

Smaller curved mirrors typically mounted below or beside the main mirror. These eliminate blind spots by providing a wider field of view. DOT regulations require trucks to have adequate blind spot coverage, making these essential.

Hood Mirrors

Mounted on the hood or fender, these mirrors help drivers see the area directly in front of and beside the truck — critical for low-speed maneuvering, dock approaches, and pedestrian safety.

Mirror Features: What to Look For

Modern aftermarket truck mirrors offer several features that improve safety and convenience:

Power Adjustment

Electrically adjustable mirrors let you fine-tune positioning from inside the cab without climbing out. Essential for drivers who share trucks or need to adjust frequently. Most newer models from Freightliner, Kenworth, and Peterbilt come standard with power mirrors.

Heated Glass

Heated mirrors prevent ice buildup and condensation in cold weather. If you run routes through northern states or Canada, heated mirrors are practically a necessity. Most aftermarket power mirrors from EverTrust include the heating element.

Chrome vs Black Housing

Chrome housing gives a classic, polished look and matches chrome bumpers and trim. Black housing offers a modern, aggressive appearance and hides road grime better. Both options are available for most truck models at EverTrust Parts.

Semi Truck Mirrors by Brand

Freightliner Cascadia Mirrors

The Cascadia uses a distinctive aerodynamic mirror design. Replacement options include complete assemblies with power adjustment and heating. Common replacement part for Cascadia trucks after 2008, especially the 2018+ new Cascadia design. Shop Freightliner mirrors.

Kenworth T680 & T880 Mirrors

Kenworth mirrors feature a sleek, integrated design. The T680 and T880 share similar mirror mounting points but have different housing shapes. Power-heated assemblies are the most popular replacement choice. Shop Kenworth mirrors.

Peterbilt 579 & 389 Mirrors

Peterbilt mirrors are known for their durability. The 579 uses a modern aerodynamic design while the 389 features the classic long-nose truck style. Both are available in chrome and black from EverTrust. Shop Peterbilt mirrors.

International LT & ProStar Mirrors

International trucks use a modular mirror design that makes replacement straightforward. The LT series and ProStar share some mirror components. Hood mirrors are especially popular replacements for International models. Shop International mirrors.

Volvo VNL Mirrors

Volvo VNL mirrors feature integrated turn signals on newer models. Replacement assemblies include the complete housing, glass, and motor. Shop Volvo mirrors.

How to Replace a Semi Truck Mirror

Most semi truck mirror replacements are straightforward bolt-on jobs that take 30-60 minutes per side:

Step 1: Disconnect the electrical connector (for power/heated mirrors) accessible behind the door panel or at the mirror base.

Step 2: Remove the mounting bolts — typically 3-4 bolts accessible from inside the cab or behind a trim panel.

Step 3: Carefully remove the old mirror assembly, noting the position of any spacers or gaskets.

Step 4: Mount the new mirror assembly, reconnect the electrical connector, and adjust for proper visibility.

When to Replace Your Truck Mirrors

Replace your semi truck mirrors immediately if you notice cracked or missing glass, a loose or wobbly mirror housing, failed power adjustment or heating, excessive vibration at highway speed, or faded or peeling chrome finish. Driving with damaged mirrors is a DOT violation and a serious safety hazard.

Frequently Asked Questions

Are aftermarket truck mirrors the same quality as OEM?

Quality aftermarket mirrors from reputable suppliers like EverTrust use the same materials and manufacturing standards as OEM. The main difference is price — aftermarket mirrors cost 40-60% less without sacrificing fit or durability.

Can I upgrade from manual to power mirrors?

In most cases, yes. However, you may need to run additional wiring to the mirror location. Check your truck's wiring harness — many trucks came pre-wired for power mirrors even if manual mirrors were installed at the factory.
