Peterbilt 567/579 Shock Absorbers

Frequently Asked Questions About Peterbilt 567/579 Shock Absorbers

Will these shock absorbers fit my Peterbilt 567 or 579?

Shock absorbers for these models are designed to match the specific front and rear suspension setups used on the 567 and 579. Since these trucks can be built with different cab configurations, ride heights, and axle setups, it is important to check your truck's VIN or existing shock part number before ordering to confirm the correct fit for your specific application.

What is the difference between front and rear shock absorbers for these models?

Front and rear shocks are engineered differently to handle the distinct weight distribution and ride characteristics at each end of the truck. Front shocks typically manage steering axle movement, while rear shocks are built to handle heavier loads and rear suspension travel. Always confirm whether you need a front, rear, or matched set before purchasing.

How do I know when it's time to replace my shock absorbers?

Common signs of worn shocks include excessive bouncing, cab sway, uneven tire wear, visible fluid leaks, or a rougher than normal ride. If you notice any of these symptoms, it is a good idea to have your suspension inspected, as worn shocks can affect handling and put added stress on other suspension components.

Should I replace shock absorbers in pairs?

Many technicians recommend replacing shocks in pairs, either both front or both rear, even if only one appears worn. This helps maintain even handling and ride quality on both sides of the truck, since shocks tend to wear at a similar rate over time.

Are these shock absorbers OEM or aftermarket, and does it matter?

Our selection includes both OEM and quality aftermarket options for the Peterbilt 567 and 579. OEM shocks are built to match factory specifications exactly, while aftermarket options can offer a cost-effective alternative. The right choice depends on your budget, driving conditions, and whether you prefer to stick with factory-matched components.
