Frequently Asked Questions About Peterbilt 352 Frame Steps & Acc.
Will these frame steps fit my specific Peterbilt 352 model year?
Most frame steps in this category are designed to fit Peterbilt 352 models from 1969 through 1987. However, minor variations exist between early models (1969-1979) and later models (1980-1987) due to frame rail spacing changes. Always verify your truck's exact year and measure the mounting points before ordering. If you're unsure, contact us with your OEM and we'll help confirm compatibility.
What's the difference between aluminum and stainless steel frame steps?
Aluminum steps are lighter (typically 15-20 lbs per set) and won't rust, making them ideal for weight-conscious drivers. They require regular polishing to maintain shine. Stainless steel steps are heavier (25-35 lbs per set) but offer superior durability and resistance to bending under heavy use. Stainless maintains its appearance longer with less maintenance. Both materials handle road salt well, but stainless steel provides better long-term value for heavy-duty applications.
Do I need to drill holes in my frame to install these steps?
Most quality frame steps for the Peterbilt 352 are designed to use existing frame holes or clamp-on mounting systems. Bolt-on models typically utilize factory mounting points without drilling. Clamp-on styles use heavy-duty U-bolts that grip the frame rails. Some universal steps may require drilling, so check the product description carefully. We recommend bolt-on options for the most secure installation without frame modification.
How many steps do I need, and what's the standard mounting height?
The number of steps depends on your truck's configuration. Standard cab models typically use 2-3 steps per side, while extended hood models may need 3-4 steps. Steps should be mounted 12-16 inches apart vertically, with the first step positioned 18-24 inches from the ground. Consider your typical footwear and climbing comfort when determining placement. Many drivers prefer the bottom step slightly forward of the door for easier cabin access.
Will aftermarket steps affect my ground clearance or DOT compliance?
Properly installed frame steps should not significantly impact ground clearance. Most steps extend 4-6 inches from the frame rail and maintain at least 12 inches of ground clearance when mounted correctly. All steps in our catalog meet DOT requirements for commercial vehicles. However, avoid steps that extend beyond the width of your mirrors, as this may create clearance issues and potential violations in some states.
