What are the correct air tank sizes for my Peterbilt 379, and will aftermarket tanks affect my air system performance?
Most Peterbilt 379 models use standard 11" x 37" air tanks, though some extended hood models may accommodate longer tanks. When replacing OEM tanks with aftermarket options, ensure the total air capacity meets or exceeds your original system specifications. Chrome and aluminum aftermarket tanks typically perform identically to OEM steel tanks, but verify the port sizes match your existing air lines (usually 3/8" or 1/2" NPT). Always maintain proper air volume for your brake system requirements.
Will these air tank wraps and heat shields fit my specific year Peterbilt 379?
Air tank wraps and heat shields for Peterbilt 379 models are generally universal from 1987-2007, as the frame rail spacing and tank mounting locations remained consistent. However, custom exhaust setups or aftermarket modifications may require adjustable mounting brackets. Extended hood models (379X) and day cabs use the same tank dimensions but may have different mounting bracket spacing. Measure your existing tank diameter and length before ordering wraps to ensure proper fitment.
How difficult is it to install new air tanks and mounting brackets without removing the cab?
Air tank replacement can be completed without cab removal on most Peterbilt 379 trucks. You'll need basic hand tools, air line wrenches, and approximately 2-4 hours per side. The most challenging aspect is accessing the upper mounting bolts near the frame rail. Disconnect the battery, drain air system completely, and support the tank while removing mounting straps. New mounting brackets typically use existing frame holes. Professional installation is recommended if you're uncomfortable working with air brake systems.
What's the difference between polished aluminum and chrome air tanks in terms of durability and maintenance?
Polished aluminum tanks are lighter (approximately 15-20 lbs less than steel) and won't rust, but require regular polishing to maintain shine and can develop white oxidation if neglected. Chrome-plated steel tanks offer a mirror finish that's easier to maintain with simple cleaning, but can develop rust if the chrome is chipped or scratched. Both options last 10+ years with proper care. Aluminum is preferred in coastal areas due to superior corrosion resistance, while chrome typically costs less upfront.
Do I need special mounting hardware when upgrading from steel to aluminum air tanks?
Standard mounting straps and brackets work with both steel and aluminum tanks as long as the diameter remains the same. However, aluminum tanks may require rubber isolation pads between the tank and metal straps to prevent galvanic corrosion. Most quality aluminum tank kits include these pads. Torque specifications differ slightly - aluminum tanks require 35-40 ft-lbs on mounting straps versus 45-50 ft-lbs for steel. Always use stainless steel hardware with aluminum tanks to prevent corrosion.
