Frequently Asked Questions About Peterbilt 379 Clamps, Brackets & Mounting

Will these clamps and brackets fit my specific year Peterbilt 379?

Most clamps and brackets for the Peterbilt 379 are designed to fit model years 1987-2007, as the frame rails and mounting points remained largely consistent throughout production. However, some components may have slight variations between early models (1987-1995) and later models (1996-2007). Always check the product description for specific year compatibility, and when in doubt, measure your existing mounting points or contact us with your VIN for verification.

What's the difference between stainless steel and chrome-plated brackets?

Stainless steel brackets offer superior corrosion resistance and durability, especially in harsh weather conditions or areas with road salt. They maintain their appearance longer but typically cost more upfront. Chrome-plated steel brackets provide an excellent mirror finish at a lower price point but may require more maintenance and can eventually show rust if the chrome chips or wears. For daily drivers in tough conditions, we recommend stainless steel. For show trucks or mild climates, chrome-plated options work well.

Do I need special tools or professional installation for mounting brackets?

Most clamps and brackets can be installed with standard hand tools including wrenches, sockets, and screwdrivers. However, some heavy-duty brackets may require drilling new holes, which needs a quality drill and proper bits for steel. Air tool brackets specifically require an air compressor line installation. We recommend having a torque wrench to ensure proper tightness according to manufacturer specifications. While many drivers successfully install these parts themselves, complex mounting systems or frame modifications should be handled by a qualified technician.

How do I know what size clamps I need for my exhaust or air lines?

Measure the outside diameter of your pipes or hoses where the clamp will be installed. Common sizes for Peterbilt 379 exhaust clamps are 5-inch and 6-inch, while air line clamps typically range from 1/4-inch to 1/2-inch. Band-style clamps usually have about 1/2-inch of adjustment range. For exhaust systems, also consider whether you need standard duty (14-gauge) or heavy duty (10-gauge) clamps based on your exhaust weight and vibration levels.

Why are my brackets vibrating loose even after proper installation?

Vibration is the main enemy of mounting hardware on semi trucks. First, ensure you're using lock washers or thread-locking compound on all fasteners. Grade 8 bolts are recommended for critical mounting points. Check that brackets are rated for the weight they're supporting - undersized brackets will flex and work loose over time. For persistent issues, consider adding rubber isolation mounts between the bracket and frame to dampen vibrations. Also verify that whatever you're mounting isn't creating excessive movement or stress on the bracket during normal operation.
