Pacbrake is a comprehensive supplier of performance braking and suspension solutions for heavy-duty trucks, commercial vehicles and off-road builds. While it began with advanced diesel exhaust brake systems engineered for control and safety under demanding loads, the product line has grown to include robust air spring suspension kits and leveling systems that support heavier loads, enhance ride quality and maintain vehicle geometry. The air suspension kits from Pacbrake feature heavy-duty air bags (helper springs) with one-piece aluminum end caps and multiple support wires for strength under repeated load cycles. These systems are engineered to eliminate sag, reduce sway and prevent bottoming out when hauling heavy equipment, towing trailers or carrying uneven loads. The kits include corrosion-resistant roll plates, precision-cut powder-coated brackets and all hardware required for bolt-on installation. In application, Pacbrake’s air spring and leveling kits allow drivers to maintain ride height and stability whether the vehicle is empty or fully loaded. This ensures consistent handling, tire contact and braking performance across load conditions. The company’s suspension solutions are not generic, but built with vehicle-specific engineering in mind, tailored brackets, mounts and components for exact fit. Combined with their exhaust brake technology, Pacbrake offers a full spectrum of performance upgrades: managing power, chassis control and load dynamics. Their systems support fleets, vocational trucks, off-road rigs, and performance builds. The focus throughout is durability, engineered integration and long service life. For anyone upgrading their truck for heavier duty work, frequent towing or more demanding terrain, Pacbrake’s air spring suspension kits deliver practical load-support performance, and their braking systems offer the control and safety needed when the vehicle is pushed beyond standard usage.
