Finishes vary by part and may include raw steel, powder coating, or galvanized coatings to help resist corrosion and withstand everyday wear on the road.

Do these parts require professional installation?

Proper torque specs, alignment, and welding procedures (where applicable) are important to maintain the structural integrity of the frame.

Are these components compliant with DOT and weight regulations?

Frame and chassis modifications can affect your truck's overall weight rating, axle spacing, and structural compliance. It's important to verify that any replacement or added component keeps your truck within DOT guidelines and your fleet's or state's weight and safety regulations. If you're unsure how a specific part affects your truck's ratings, consult with a qualified technician before installation.
