Overview

Overview
This new 2027 Peterbilt Model 567 conventional day cab tractor is configured for construction dump service, on and off highway, and spec’d to pull a 53-foot semi-end dump trailer. It carries a GVWR of 53,200 lbs and a GCW rating of 80,000 lbs, with a maximum grade rating of 6%. The intended duty cycle is 90% highway and 10% Class B roads.

Engine & Drivetrain
The Cummins X15 Performance Series engine is rated at 525 HP at 1,900 RPM (governed at 1,900) with 1,850 lb-ft of torque at 1,000 RPM, and is a 2024-series emissions engine that is CARB compliant. The powertrain is optimized for balance in service with frequent start and stop cycles, with a typical operating speed of 65 MPH. The engine includes a Jacobs compression brake with controls on the right-hand column, a predictive cruise control package, and an engine idle shutdown timer. Supporting equipment includes a PACCAR 160-amp brushed alternator, a PACCAR 12V starter, four PACCAR Premium 12V dual-purpose batteries totaling 2,920 CCA, a 110–120V immersion-type block heater, a 37.4 CFM air compressor, a 2-speed fan clutch for frequent start/stops, and a high-efficiency cooling system. The fuel system adds a PACCAR fuel/water separator with an extended service interval and fuel heat for the fuel filter. A firewall-mounted air cleaner feeds the engine. The exhaust is a dual side-of-cab layout with a left-hand stack aesthetic and a single-module DPF/SCR mounted under the right side of the cab. It finishes with 42-inch, 7-inch-diameter chrome standpipes with clear coat and 45-degree curved tips. EMUX electronics architecture, a remote PTO/throttle provision with a 12-pin connector in the engine bay, a battery jumper terminal under the hood, a Kissling 300A cab power disconnect switch, and a low-voltage disconnect system round out the electrical package.

Power goes through an Eaton Endurant XD Pro 18-speed automated transmission (EXDP-18F118D) with an oil-to-water cooler, a column-mounted shifter on the right side, and a performance shift calibration. A dash switch enables Rock Free Mode, and Neutral Coast Mode is active at the pedal only. Drivelines are an RPL20 interaxle and an RPL25 SD main driveline with one midship bearing. A dash-mounted single-acting electric-over-air PTO control is included.

Chassis & Axles
The wheelbase measures 220 inches, with a cab-to-axle of 129.9 inches, front axle to back of cab of 90.1 inches, and cab to end of frame of 184.6 inches. The frame uses 10-5/8-inch steel rails at 5/16-inch thickness with zinc-coated anti-corrosion treatment, aluminum crossmembers, and a tapered tractor end of frame with a crossmember and kingpin cutout. The front axle is a Dana Spicer E1322IL rated at 13,200 lbs with a 3.5-inch drop and wide-track configuration. It includes Sheppard HD94 power steering with a frame-mounted reservoir, PHP10 iron Preset Plus hubs, severe-service disc brake rotors, and Meritor EX+ LS air disc brakes. The rear axle is a Dana Spicer DSH40 High Performance 40 tandem rated at 40,000 lbs with a 3.70 ratio. It carries tandem differential locks with speed interlock, PHP10 iron Preset Plus hubs, severe-service rotors, and Meritor EX+ LS air disc brakes. Synthetic lubricant is used in all axles. GAWR is 13,200 lbs front and 20,000 lbs on each tandem axle. Safety systems include Bendix ESP electronic stability with automatic traction control, 6S6M anti-lock braking, a tire pressure monitoring system, and a pneumatic park brake. The air system features a Bendix AD-HF EP heated air dryer with a coalescing filter and extended purge, polished aluminum air tanks mounted outside the frame rails, pull cords on all tanks, nylon chassis hose, and a self-returning dash-mounted brake hand valve.

Suspension
Up front, taper leaf springs rated at 13,200 lbs are fitted with Tenneco shocks and 30mm spring spacer blocks. The rear uses Peterbilt Low Air Leaf lightweight suspension rated at 40,000 lbs with 52-inch axle spacing, along with a dash-mounted dump switch with indicator light.

Cab & Interior
The 121-inch BBC aluminum cab has a Metton hood with a set-forward front axle and a stainless steel crown and grille with tilt assist, plus a bright side-of-hood air intake bezel. Cab air suspension, a thermal insulation package, and the SmartSound insulation package keep the ride quiet. The Premier interior is finished in Sterling Gray with a rubber floor. The driver gets a Peterbilt LX premium-level seat with air ride, high back, and leather. The passenger seat is a Peterbilt ST with air ride, high back, and vinyl, and both seats are black and have armrests. A multi-function steering wheel with audio and cruise controls sits on a tilt/telescoping column. The 15-inch digital instrument cluster displays engine hours, PTO hours, turbo boost, percent torque, transmission clutch temperature, air filter restriction, and brake application pressure. It is supplemented by bright-bezel 52mm backlit gauges for front and rear drive axle oil temperature, engine oil temperature, trailer reservoir air pressure, air suspension pressure, and fuel filter restriction. Three additional dash switches, a traction control deactivation switch, and an electric dump switch wired to the back of cab for a truck tailgate are included. Brake lights are disabled with engine brake use.

Audio is a ConcertClass AM/FM/weatherband radio with 3.5mm aux, Bluetooth phone and audio, a USB port, a four-speaker mid-level package, and radio mute in reverse.
