Frequently Asked Questions
Q: Will this fender step fit my Peterbilt 379?
A: This step is designed for the 1987–2007 Peterbilt 379, replacing OEM part numbers L82-6003P. This is the driver side (LH) version. Verify your OEM part number and side before ordering. Call or text 260-440-2101 for fitment verification.
Q: What is the difference between sand-cast and injection-molded aluminum?
A: Sand-cast aluminum is poured into a sand mold, producing a denser, stronger part with better structural integrity. Injection-molded parts are made under pressure and can be thinner and more prone to cracking under heavy use. Sand-cast is the preferred method for heavy-duty truck steps.
Q: Do I need the driver side or passenger side?
A: This listing is for the driver side (LH). If you need the passenger side (RH), call or text 260-440-2101 and we can help you find the correct part.
Q: How quickly can this step ship?
