Frequently Asked Questions About Peterbilt 387 Roof Trim

What model years does the Peterbilt 387 roof trim fit, and are there different versions I need to know about?

Peterbilt 387 roof trim is designed specifically for model years 1999-2010. There are two main variations: pre-2005 models typically use a 3-piece trim set, while 2005-2010 models use a 4-piece configuration. Always verify your truck's exact year and cab configuration before ordering, as extended hood models may require different trim lengths than standard configurations.

Is the roof trim made of stainless steel or chrome-plated plastic, and how long will it last?

Most quality Peterbilt 387 roof trim options come in either 304-grade stainless steel or heavy-duty ABS plastic with triple chrome plating. Stainless steel trim typically lasts 10-15 years with minimal maintenance, while chrome-plated versions generally maintain their finish for 5-7 years depending on exposure to road salt and weather conditions. Stainless options cost more initially but require less upkeep and resist pitting better in harsh climates.

Can I install the roof trim myself, or do I need professional help?

Installation is straightforward and typically takes 1-2 hours with basic tools. You'll need a drill with metal bits, measuring tape, masking tape for alignment, and silicone sealant. The trim usually attaches with self-tapping screws through pre-marked points. Many drivers successfully complete this as a DIY project, though having a helper makes alignment easier. Professional installation typically runs $100-200 if you prefer that route.

Will aftermarket roof trim affect my cab's water seal or cause leaks?

Properly installed roof trim should not cause leaks. Quality trim pieces are designed to follow factory contours and include rubber gaskets or recommend specific sealants for weatherproofing. Apply a thin bead of clear silicone sealant along the trim edges during installation, and ensure all mounting holes are properly sealed. Avoid over-tightening screws, which can warp the trim and create gaps.

What's the difference between OEM and aftermarket roof trim in terms of fit and appearance?

OEM Peterbilt trim offers exact factory specifications but costs significantly more, often 2-3 times aftermarket prices. Quality aftermarket options from reputable manufacturers provide nearly identical fit and appearance, with differences typically unnoticeable once installed. Look for trim that specifies "OEM-style" or "direct replacement" fitment. The main visible difference is usually in the mounting tab placement, which remains hidden after installation.
