Will a grille guard fit my specific year Peterbilt 389, and what about aftermarket bumpers?
Most grille guards designed for the Peterbilt 389 fit model years 2008 and newer. However, fitment can vary if you have an aftermarket bumper installed. Factory bumpers typically ensure direct compatibility, while aftermarket bumpers may require additional brackets or modifications. Always verify your bumper type and model year before ordering. If you have a Texas, Valley Chrome, or other aftermarket bumper, contact us with your specific bumper model for compatibility confirmation.
What's the difference between aluminum and stainless steel grille guards, and which holds up better?
Aluminum grille guards are lighter (typically 40-60 lbs) and won't rust, making them ideal for weight-conscious drivers and coastal areas. They require regular polishing to maintain shine. Stainless steel guards are heavier (80-120 lbs) but offer superior impact protection and maintain their mirror finish longer with less maintenance. Both materials are durable, but stainless steel generally provides better protection against deer strikes and debris, while aluminum offers better fuel economy due to reduced weight.
How difficult is the installation, and what tools will I need?
Installation typically takes 1-2 hours and requires basic hand tools: socket set (usually 3/4" and 7/8"), wrenches, and possibly a drill for certain models. Most grille guards use existing bumper mounting points, though some designs may require drilling 2-4 holes. The main challenge is the weight - having a second person helps significantly during alignment. Professional installation runs $150-300 if you prefer not to DIY. Detailed instructions are included with each guard.
Do grille guards come with light mounting tabs, and what styles are available?
Style options include horizontal bar, vertical bar, and combination designs. Most models include pre-drilled light mounting tabs that accommodate standard 4" or 6" auxiliary lights. Popular finishes are mirror polish, brushed, and powder-coated black. Some guards feature wraparound protection extending to the headlights, while others focus on center grille coverage. Consider your driving conditions - horizontal bars offer better small debris protection, while vertical designs provide maximum airflow.
Will a grille guard affect my truck's cooling or front-end alignment?
Properly designed Peterbilt 389 grille guards maintain adequate airflow and won't affect cooling when installed correctly. The added weight (40-120 lbs depending on material) is within factory specifications and won't impact alignment. However, guards that block more than 30% of the grille area may cause slight temperature increases during extreme conditions or heavy hauling. Most drivers report no noticeable difference in normal operation. Ensure at least 2-3 inches of clearance between the guard and radiator for optimal airflow.
