A lip extension allows for more reach when the bucket is lowered, making it easier to scoop up material from further distances. This can be especially useful in operations where the material is spread out or located in hard-to-reach spots.
- Cost-Effective Solution
Instead of purchasing a completely new bucket, a lip extension offers a more affordable solution for expanding the functionality of your existing equipment. It’s a quick and cost-effective way to improve performance without replacing the entire bucket.
- Versatility
Depending on your work environment, a lip extension can be especially helpful for a variety of tasks. Whether you’re working in construction, landscaping, or material handling, a loader bucket lip extension can make your machine more adaptable to different jobs.
Factors to Consider When Purchasing a Bucket Lip Extension
- Compatibility
Ensure that the lip extension you purchase is compatible with your loader and bucket model. There are various sizes and designs available, so it’s important to check that the extension fits your machine correctly. Manufacturers often provide compatibility charts or guidelines to help you choose the right one.
- Material and Durability
A bucket lip extension must be built to withstand tough work conditions. Look for extensions made from high-strength steel or alloy materials that offer durability and longevity. Choose an extension designed for your type of work to ensure it handles the wear and tear of daily use.
- Attachment Type
Extensions can come in different attachment types, such as welded-on or bolt-on designs. Depending on your preferences, choose an extension that suits your needs. A bolt-on design might be easier to install and remove, while a welded-on extension could offer more security and stability.
- Manufacturer and Brand
Reputable manufacturers and trusted brands will provide higher-quality products that meet the necessary standards for performance and safety. Some well-known brands that offer bucket lip extensions include Caterpillar, John Deere, and Bobcat, but many third-party suppliers also offer quality options.
- Price
The cost of a bucket lip extension can vary depending on the brand, material, and size. It’s important to compare prices from different suppliers to find an extension that offers good value for your investment. While some low-cost extensions may seem appealing, always consider the long-term durability and functionality of the product.
Where to Buy a 7 Loader Bucket Lip Extension
- Dealerships and OEM Suppliers
The first place to check for a loader bucket lip extension is your equipment’s official dealership or Original Equipment Manufacturer (OEM). Brands like Caterpillar, John Deere, and Volvo often provide replacement parts and attachments through their authorized dealerships. They can recommend a compatible extension for your loader model.
- Online Marketplaces
Websites like Amazon, eBay, and Tractor Supply offer a wide variety of equipment parts and accessories, including bucket lip extensions. You can search for specific extensions by brand, size, and compatibility, making it easy to compare prices and options from different sellers.
- Specialized Equipment Retailers
There are several online and physical retailers that specialize in heavy equipment parts and attachments. These include companies like Parts Supply and Heavy Equipment Parts. You can often find a broader selection of accessories and parts for specific loader models.
- Third-Party Manufacturers
Several third-party manufacturers offer high-quality bucket lip extensions at competitive prices. Brands like Hensley Industries, ESCO, and others specialize in aftermarket equipment parts. These manufacturers often provide durable, performance-oriented attachments suitable for various loader brands and models.

Many local heavy equipment repair shops also sell parts and accessories for loaders. These shops may have access to custom-made or specific bucket lip extensions, and they can provide professional advice on the best options for your needs.

Introduction
The ongoing rivalry between Ford and General Motors (GM) has entered the diesel-powered pickup truck market, with both companies vying for dominance in terms of power, performance, and innovation. In this battle, Ford has recently emerged as a winner, trumping GM in the diesel pickup power war. This article takes a deep dive into how Ford's diesel engine offerings have surpassed GM's and what it means for consumers looking for the best diesel-powered trucks.
Ford's Diesel Engine Dominance
Ford has long been known for producing heavy-duty trucks with robust engines. The company’s Super Duty series, particularly the 2020 Ford F-250 and F-350 models, equipped with the 6.7L Power Stroke V8 diesel engine, is a strong contender in the diesel pickup market. - Engine Performance: The 6.7L Power Stroke V8 boasts impressive performance with a maximum horsepower rating of 475 hp and a massive 1,050 lb-ft of torque. This engine gives the Ford F-Series Super Duty trucks superior towing and hauling capabilities, which is a key selling point for diesel truck buyers.
- Towing Capacity: Ford’s Super Duty trucks equipped with this engine can tow up to 37,000 pounds with the fifth-wheel/gooseneck towing setup, while conventional towing capacity maxes out at 24,200 pounds. This exceeds many of its competitors, including GM’s heavy-duty diesel trucks.
GM's Diesel Engines and Challenges
On the other hand, GM’s diesel engines have also made significant strides in recent years. GM’s 6.6L Duramax V8 diesel, found in the Chevrolet Silverado 2500HD and GMC Sierra 2500HD models, has been a formidable competitor in the diesel pickup market. However, it still lags behind Ford in certain key performance areas.- Engine Power: The Duramax engine produces 445 hp and 910 lb-ft of torque. While this is impressive in its own right, it falls short of Ford's 6.7L Power Stroke in both horsepower and torque output.
- Towing Capacity: The 2020 GM diesel models can tow up to 35,500 pounds when using a fifth-wheel/gooseneck setup. While competitive, it still trails Ford’s towing capacity, highlighting Ford’s edge in the diesel power war.
The Impact on Consumers
The battle for diesel pickup supremacy is not just about raw power; it also involves technology, fuel efficiency, and towing features. Ford's engine performance offers significant advantages for those who need maximum towing capability and overall power for heavy-duty work. This is especially crucial for industries like construction, agriculture, and long-haul transportation.- Fuel Efficiency: Ford has also made significant improvements in fuel efficiency with the 6.7L Power Stroke V8, thanks to its advanced turbocharging and fuel injection systems. This provides consumers with a good balance of power and efficiency, making it a versatile option for those who need both performance and cost savings on fuel.
- Technology and Features: Ford's diesel-powered trucks come with advanced tech features like the Pro Trailer Backup Assist, Trailer Sway Control, and a fully integrated tow/haul mode, making them incredibly user-friendly for hauling and towing tasks. These features enhance the overall ownership experience and are appealing to those who demand high performance with ease of use.
GM's Response and Future Outlook
Despite losing this round in the diesel power war, GM continues to improve its 6.6L Duramax V8 diesel engine. The 2021 models have seen some improvements in fuel efficiency and overall engine performance, which may help close the gap. Additionally, GM is investing heavily in the electric vehicle (EV) space, which could shift the focus away from diesel engines in the coming years.- Innovation and Development: GM has also been working on improving the durability and reliability of its diesel engines, as well as incorporating more modern features like a 10-speed transmission and upgraded cooling systems to enhance engine performance.
- Electric Vehicles: As Ford and GM both enter the EV market, it will be interesting to see how their strategies evolve. Ford’s investment in electric pickups, like the all-electric F-150 Lightning, could pose new challenges to GM’s diesel-focused lineup.
Conclusion
While GM has a strong presence in the diesel pickup market, Ford’s 6.7L Power Stroke V8 engine has proven to be the more powerful and capable option for those in need of extreme towing and hauling performance. With superior horsepower, torque, and towing capacity, Ford has taken the lead in this diesel power war. However, GM continues to innovate and improve, and the future of diesel engines in pickups may evolve as new technologies and electric vehicles enter the market.
For now, Ford's diesel-powered trucks remain the go-to option for those who demand unmatched power and performance in the heavy-duty truck segment.
