The 1964 International C1100 Grunt by Weaver Customs is the kind of truck that never asks for a day off. Discovered abandoned in a Wyoming field in 2016, it’s been reborn into a tough and purposeful shop truck that embodies reliability, grit, and timeless craftsmanship.
From Forgotten Field Find to Shop Hero
Grunt’s story began in Cheyenne, Wyoming, where the team from Weaver Customs found it waiting for a second life. Since then, it has become the shop’s go-to hauler and a favorite among the crew , often jokingly named the “Employee of the Month.” Its strength and character reflect the very essence of what Weaver Customs stands for: hard work and passion for performance.
Engineered for Power and Reliability
At the heart of Grunt lies a 5.9-liter Cummins diesel engine, renowned for its durability and torque. Paired with a full manual 48RE transmission, the setup delivers raw pulling power and mechanical simplicity. The Flowmaster exhaust enhances the truck’s deep, commanding tone while keeping it true to its utilitarian spirit.
Custom Suspension and Handling
Underneath, Grunt features a Mustang II front suspension combined with a 4-linked Ford 9-inch rear housing. The system uses Midnight 4×4 rod ends, tubing, and RideTech adjustable coilovers on all four corners, allowing the truck to handle its workload with remarkable stability and control. It’s a setup designed to take on heavy tasks without sacrificing ride comfort.
Performance and Stopping Power
GM disc brakes provide reliable stopping force, matching the truck’s impressive drivetrain capabilities. The custom one-off 22×9-inch billet wheels not only enhance its stance but also showcase Weaver Customs’ attention to functional design. Every component has been selected to perform under pressure and look good doing it.
Interior and Functional Details
Inside, the cabin is built for utility and comfort. Dakota Digital gauges offer clear visibility, while a B&M Racing shifter ensures precise control over the 48RE gearbox. JW Speaker lights illuminate the road ahead, and a Kicker audio setup adds a touch of modern convenience for long workdays behind the wheel.
Power and Performance Highlights
The 5.9-liter Cummins diesel engine defines Grunt’s identity, offering immense low-end torque and long-lasting reliability. Together with its reinforced suspension and upgraded braking system, it delivers consistent performance , a true representation of a truck built to work as hard as it looks.
