The A33-1266-100BP is a fairing reinforcement bracket for the Kenworth T680 Next Gen (2022 and newer), engineered to replace OEM part A33-1266-100. A33-1266-200 and A33-1266-300 share the same understep reinforcement molding. The OEM part carries A33-1266-100 and A33-1266-200 molded into it, and Kenworth supersedes A33-1266-200 to A33-1266-100. Designed for the understep fairing assembly, it provides the structural rigidity and secure mounting support the outer panel depends on. Direct bolt on at factory mounting points. No drilling, no modifications required.

Full description

The OEM A33-1266-100 is standard injection-molded plastic. Under sustained vibration, thermal cycling, and road debris, it degrades, cracking and chipping until the assembly loses its support. The A33-1266-100BP is rebuilt in carbon fiber reinforced plastic with a reinforced rib structure and additional material in high-stress areas.

Also sold with its companion bracket as a complete bracket set for the full understep panel. Full OEM vs aftermarket comparison →

Buyer warning: copies of this bracket are sold in PETG and ABS. Per manufacturer data, PETG deforms under load at 68 °C and ABS at 87 °C. Both creep under constant step load, leading to cracked mounts and early failure. The A33-1266-100BP is carbon fiber reinforced plastic only, rated to 170 °C.
