Frequently Asked Questions About Peterbilt 375/377 Air Tanks, Wraps & Mounting
What air tank sizes are compatible with Peterbilt 375 and 377 models?
Peterbilt 375 and 377 models typically accommodate air tanks ranging from 11 inches to 13 inches in diameter. The most common sizes are 11x37 inch and 13x35 inch tanks. Your specific truck configuration and frame rail spacing will determine the maximum tank size. Models from 1987-2007 generally have the same mounting points, but always verify your frame rail measurements before ordering.
Will these air tank wraps fit my specific year model, and how do I ensure proper fitment?
Our air tank wraps are designed to fit Peterbilt 375 models from 1987-2007 and 377 models from 1999-2007. To ensure proper fitment, measure your existing tank diameter and length, then check the clearance between your tank and frame rails. Most wraps require at least 1/2 inch clearance on all sides. Pre-2000 models may have slightly different mounting bracket spacing, so double-check your measurements against the product specifications.
How difficult is it to install air tank mounting brackets, and what tools are required?
Installation typically takes 2-4 hours per side for experienced mechanics. You'll need basic hand tools including wrenches (typically 3/4" and 7/8"), a drill with metal bits if new holes are required, and a torque wrench. The main challenges include aligning brackets properly to avoid air line interference and ensuring adequate clearance from exhaust components. Some installations may require minor drilling or modification of existing mounting holes.
What's the difference between aluminum and stainless steel air tanks for my Peterbilt?
Aluminum tanks are lighter (typically 40-50% less weight than steel), resist corrosion better, and are ideal for weight-conscious applications. However, they cost more upfront. Steel tanks are more affordable and extremely durable but require regular maintenance to prevent rust. For trucks operating in high-salt environments or humid climates, aluminum is strongly recommended despite the higher initial cost.
Do polished stainless wraps require special maintenance to keep their shine?
Yes, polished stainless wraps need regular maintenance to maintain their mirror finish. Clean them every 2-3 weeks with a quality stainless steel cleaner and microfiber cloth. Avoid abrasive cleaners or steel wool. For trucks in harsh environments, apply a stainless steel polish monthly to protect against water spots and road film. Neglecting maintenance will result in dulling and potential pitting over time.
