Frequently Asked Questions About Peterbilt 367 Leaf Springs, Hangers & Acc.
What years and configurations of Peterbilt 367 do these leaf springs fit?
Our leaf springs are designed to fit Peterbilt 367 models from 2007 to present. However, compatibility depends on your specific truck configuration, including axle rating, suspension type (air ride or spring), and whether you have a single or tandem axle setup. We recommend checking your VIN or calling our technical support team at 417-775-7878 with your truck's specifications to ensure proper fitment before ordering.
How difficult is it to replace leaf springs on a Peterbilt 367, and what tools are required?
Replacing leaf springs typically requires 4-6 hours for an experienced mechanic and involves lifting the truck, supporting the axle, and dealing with high-tension components. Essential tools include a heavy-duty jack, jack stands rated for commercial trucks, impact wrenches, torque wrenches, and spring compressors. Due to safety concerns and the need for proper torque specifications, we strongly recommend professional installation unless you have commercial truck repair experience.
What's the difference between OEM and aftermarket leaf springs for the 367?
OEM leaf springs are manufactured to Peterbilt's exact specifications and typically carry a higher price point but ensure perfect fit and ride quality. Our aftermarket options from trusted brands like Dayton Parts and Triangle Suspension offer comparable quality at a more competitive price, often with improved steel grades and enhanced corrosion resistance. Most aftermarket springs meet or exceed OEM load ratings and come with warranties ranging from 1-3 years.
How do I know when my leaf springs need replacement versus just new bushings or hangers?
Signs that indicate full spring replacement include visible cracks in the leaves, permanent sagging causing uneven ride height, separated or shifted leaves, or a harsh ride quality that persists after bushing replacement. If your springs are intact but you're experiencing squeaking, minor ride height issues, or handling problems, replacing just the bushings and hangers (typically every 100,000-150,000 miles) may resolve the issue at a fraction of the cost.
Are heavy-duty leaf springs worth the upgrade for my application?
Heavy-duty leaf springs are recommended if you frequently haul at or near maximum capacity, operate on rough terrain, or have experienced premature spring failure. These upgraded springs typically feature additional leaves, thicker steel construction, and higher load ratings. While they may create a slightly stiffer ride when empty, they provide better stability under load and extended service life, making them cost-effective for severe-duty applications like logging, construction, or heavy hauling.
