Chassis Extension

Maximise the chassis strength and payload capacity of your LandCruiser 70 series (ute conversion) with a chassis extension. Chassis extensions allow extended-length trays and shifts

tray-load centre of gravity further forward over the rear axle. This in part improves the payload capacity, but also significantly improves on and off road handling with heavy loads.

Combined with Boss’ range of trays, chassis extensions can facilitate forward underbody boxes, utilising increased under-tray space. The process is drive in, drive out, and includes all fuel system, brake system and wiring loom extensions necessary.

All solutions offered by Boss Aluminium are completely customisable to individual requirements and delivered with a Lifetime Guarantee on workmanship and materials.
