Frequently Asked Questions About Freightliner Columbia 112/120 Door & Cab Side Accessories

Will these door and cab accessories fit my specific year Freightliner Columbia?

Most of our door and cab side accessories are designed to fit Freightliner Columbia 112 and 120 models from 2001-2017. However, there were minor design changes in 2011 that affect some components. Door handles, mirrors, and window regulators typically fit across all years, but door panels and interior trim pieces may vary between pre-2011 and post-2011 models. Always check the product description for specific year compatibility, or contact our support team with your VIN for verification.

Are aftermarket door handles and latches as durable as OEM parts?

Quality varies significantly between manufacturers. Our premium aftermarket door handles and latches are made from reinforced composite materials or die-cast metal that often exceeds OEM specifications. Look for brands like Dorman, Velvac, and United Pacific, which use heavy-duty materials designed for commercial truck applications. Budget options may use thinner plastics that can crack in extreme temperatures. We recommend investing in mid-to-premium grade components for doors, as they endure constant use and weather exposure.

Can I install door panels and interior accessories myself, or do I need professional help?

Most door panels, arm rests, and grab handles can be installed with basic tools in 30-60 minutes per side. You'll typically need a panel removal tool, Phillips and flathead screwdrivers, and a 10mm socket. Door panels require careful removal of clips without breaking them. Window regulators and door latches are more complex, requiring door panel removal and precise alignment. These typically take 2-3 hours per door and may require assistance to hold components in place during installation.

What's the difference between chrome, stainless steel, and plastic chrome accessories?

Stainless steel accessories offer the best longevity, resisting rust and maintaining shine with minimal maintenance. Chrome-plated steel provides an excellent mirror finish but requires regular polishing and can eventually rust if the plating chips. Plastic chrome (ABS with chrome finish) is lightweight and won't rust but can yellow or peel after 2-3 years of sun exposure. For critical components like mirror brackets and door handles, we recommend stainless steel. For decorative trim pieces with less wear, plastic chrome offers good value.

Why do my replacement door seals still let in wind noise and water?

Poor fitment usually stems from three issues: incorrect part selection, improper installation, or worn door hinges causing misalignment. Columbia door seals come in different profiles for different build years and door styles. Ensure you're getting the correct profile by comparing your old seal's cross-section. During installation, the seal must be fully seated in its channel without stretching or bunching. If properly installed seals still leak, check door alignment - worn hinges or striker plates often need adjustment or replacement to achieve proper door closure and seal compression.
