Challenge Boost A Load Air Chamber

Challenge Boost A Load Air Chamber

This is a replacement air chamber for Challenge Cook Brothers (CCB) rear discharge concrete mixers equipped with the Boost-A-Load system. The Boost-A-Load is a trailing lift axle that is deployed to increase the vehicle's legal payload capacity by distributing weight over a longer wheelbase to comply with state bridge formulas. This air chamber is a critical component of the axle's air suspension, responsible for raising and lowering the axle as needed. Failure of this part would render the Boost-A-Load system inoperable, potentially leading to overweight violations or reduced payload.

Key Features

• Direct replacement for the original Challenge Cook Brothers part
• Enables operation of the Boost-A-Load lift axle system
• Critical for maximizing legal payload and vehicle versatility
• Actuated by the truck's compressed air system
