Frequently Asked Questions About Peterbilt 352 Cab, Sleeper & Cowl Panels
What years and models are compatible with these Peterbilt 352 panels?
Our Peterbilt 352 cab, sleeper, and cowl panels are designed to fit 1979-1987 Peterbilt 352 models. However, compatibility can vary based on whether your truck has a standard cab or extended cab configuration. We recommend verifying your specific OEM and cab style before ordering. If you're unsure about fitment, our customer service team can help confirm compatibility with your exact truck specifications.
Are these panels made from the same gauge steel as OEM parts?
Most of our replacement panels are manufactured from 18-gauge steel, which matches or exceeds OEM specifications for Peterbilt 352 models. Some lighter trim pieces may use 20-gauge steel where appropriate. All panels feature proper stamping and formed edges to ensure structural integrity. We also offer aluminum options for certain cowl panels if you're looking to reduce weight.
Do I need to drill new holes or modify these panels during installation?
Our panels are designed as direct replacements with pre-drilled mounting holes that align with factory specifications. In most cases, no additional drilling is required. However, due to variations in older trucks and previous repairs, minor adjustments or hole elongation may occasionally be necessary. All panels include the correct bends, flanges, and mounting points to match your original configuration.
What primer or coating comes on these panels, and do they need additional prep work?
Our panels typically come with an e-coat primer that provides basic rust protection during shipping and storage. This primer is not a finish coat and will require proper surface preparation before painting. We recommend scuffing the e-coat with 320-400 grit sandpaper, applying a quality automotive primer, and then your choice of paint. Some customers prefer to have panels media blasted before painting for optimal adhesion.
How difficult is it to replace cab corner panels and rockers on a 352?
Cab corner and rocker panel replacement requires intermediate to advanced fabrication skills. You'll need to cut out the damaged sections, properly prepare the mounting surfaces, and weld in the new panels. Critical areas include maintaining proper door gaps and ensuring water-tight seals. Most installations require 4-8 hours per side depending on the extent of damage. We recommend professional installation if you're not experienced with bodywork and welding, as improper installation can lead to alignment issues and water leaks.
