Selecting the correct bumper requires verifying the specific truck series (e.g., HOWO 7, HOWO A7, or HOWO T7H) as mounting points and dimensions vary significantly. You must match the OEM Part Number (such as WG1642240001) to ensure 100% compatibility. Additionally, consider the operating environment: for mining or heavy construction, prioritize heavy-duty steel bumpers with reinforced thickness, while for standard highway logistics, lightweight composite or standard steel options may suffice to optimize fuel efficiency.
