About Fuller

Depending on your truck or heavy equipment's type and age, transmission repairs and restoration can be taxing and costly. Fortunately, there are high-caliber replacement parts and assemblies that you can use to help your transmission work smoothly and deliver peak performance. One of the world-renowned names when it comes to transmission solutions is Fuller.

Fuller is Eaton's brand of legendary transmissions. It provides the US aftermarket and OE manufacturers around the globe with tailor-made solutions that improve the vehicle's overall efficiency, safety, drivability, and reliability.

Fuller Manufacturing was acquired by Eaton Corporation in 1958. Since then, this brand has been operating to uphold One Eaton's goal: "To provide unique solutions across a wide range of markets that keep businesses on the leading edge of change." It also aims to improve the quality of life of its customers and those who experience using its industry-leading products and services.

Fuller Parts

Engineered by experts, the Fuller parts are guaranteed to perform according to exacting original equipment standards. They are designed using Eaton's power management technologies and the latest manufacturing techniques to create products that carry the quality and dependability the Eaton Fuller name is known for. The company also offers kits that simplify and streamline vehicle and equipment servicing, restoration, rebuilding, and maintenance for maximum throughput.

Transmissions

What makes the Fuller transmissions legendary are their solid dependability and cutting-edge features and technology. They are well-engineered solutions that improve the vehicle's drivability and efficiency. Fuller's automated transmissions ensure computer-controlled shifting, which improves driving safety by making it easier for drivers to keep their eyes and attention on the road and both hands on the steering wheel.

UltraShift PLUS

Assembled on the industry's highly regarded transmission platform, the UltraShift® PLUS transmissions come smarter, tougher, and more efficient than other automated or automatic transmissions. They were introduced in 2009 to meet the rising trend of automation and address the need for balanced performance and fuel economy, and precise, guess-proof shifting. Available in six models for vocational and linehaul use and in a range of speeds and capabilities, the UltraShift PLUS automated transmissions can be the exact solution you need for your fleet's unique and exacting requirements.

RT-13 and RT-18

Crafted by the proven global leader in automated transmissions, these best-in-class 13- and 18-speed transmissions allow drivers to enjoy versatility and low-shift effort. The Eaton RT-13 and RT-18 boast groundbreaking, proprietary designs with a simple mainshaft that is not splined to the auxiliary gear. Such designs eliminate the added inertia, mass, and drag of the whole auxiliary unit. During upshifts, the low-inertia mainshaft is quickly set to synchronous for faster, smoother shifts.

Versatile 15 Speed

Designed for high-performance applications, this type of transmission features ten road speeds, along with five deep reduction gears to provide on- and off-highway versatility. It also boasts time-tested helical gearing for quieter operation, improved gear strength, and extended service life. The high-capacity tapered roller bearings on its auxiliary countershafts guarantee longer bearing lifespan. With its new mainshaft washer design, this 15-speed transmission ensures excellent driver abuse resistance and hassle-free servicing.

Remanufactured transmissions

Expertly remanufactured using Eaton's advanced procedures and technology, Fuller's standard remanufactured transmission delivers the same quality as a brand-new Eaton unit. Eaton Fuller's remanufacturing process involves meticulous dyno testing to ensure the best possible performance. These transmissions are provided with 100% genuine Eaton components and are rebuilt with the most advanced engineering updates.

Transmission Parts and Kits

Eaton Fuller carries the most comprehensive parts lineup to make transmission overhaul and service possible. The Fuller transmission parts are engineered by experts to cater to rebuilders from every angle. This brand covers subassemblies, stocked parts, overhaul and installation kits, and remanufactured transmission components.

Subassemblies

When you need to rebuild your transmission, improve its efficiency, or restore it to its proper working condition, Fuller subassemblies are available to make these tasks an easy feat. These assemblies help fleet managers and repair shops save on labor costs and tooling expenses and make technicians more confident and capable in pulling off even the most demanding jobs. Among the available assemblies composed of Fuller parts are shift bar housing, rear case, main shaft, and countershaft assemblies.

Rebuild and overhaul kits

These Fuller kits come in three categories—basic rebuild kits, basic overhaul kits, and master rebuild kits. These kits help eliminate cross-reference mistakes because they already contain the right parts you need for the job. Fuller's basic rebuild kits include bearings, springs, O-rings, gasket kit, snap rings, shim kit, and oil seal kit, while the basic overhaul kits contain sliding clutch, input shaft, and all basic rebuild parts.

Moreover, the Fuller master overhaul kits guarantee the following inclusions:

  • all basic overhaul parts
  • clutch brake
  • breather
  • hose assemblies
  • shift fork
  • miscellaneous washers
  • front bearing cover
  • synchronizer assembly
  • drive/overdrive gears
  • air/filter regulator
  • splitter and range valve (where applicable)

Clutch installation kits

Whether you are replacing the clutch or clutch-related wear components, the Fuller clutch installation kits come in handy. These kits contain all the necessary parts, hardware, and instructions to ensure smoother shifts, longer clutch life, and less wear on the transmission.

Clutches and Clutch Components

Eaton Fuller clutches are crafted for longevity. They are backed by Roadranger®, the country's largest network of drivetrain support. With such a unique combination of product durability and support, Fuller provides its aftermarket customers with peace of mind knowing that the clutch and clutch parts they get are highly efficient, reliable, and require less maintenance for maximum uptime and performance.

Advantage Series

The Advantage Series is a line of Eaton Fuller's best-selling clutches in North America. They are manufactured using industry-leading technology to meet the demands of OEM first-fit applications. Showcasing a unique patented design with a specially tuned, dual-damper system, the Advantage clutches take in engine vibrations and minimizes idle rattle. They are also fitted with soft rate springs that protect important driveline components. With their two wear indicators, Advantage Series clutches ensure improved serviceability while offering best-in-class 50,000-mile lubrication intervals.

EverTough Series

Featuring industry-standard technology and a 3-zerk release bearing, the Fuller EverTough clutches guarantee simple maintenance. The clutches from this series are available in manual-adjust and self-adjust configurations. Utilizing the company's patented self-adjusting technology, the self-adjusting clutches constantly adjust and uphold the correct bearing release position. The EverTough manual- adjust clutches, on the other hand, are fitted with proven Kwik-Adjust technology to make clutch adjustments fast and simple.
