Stop Letting A Small Filter Hold Your Truck Back

If you're still running the stock spin-on filter on your Allison transmission, you're not giving your truck the protection it deserves. The factory "shorty" filter simply can’t keep up with the demands of heavy towing, long hauls, or tuned performance. That’s where the PPE High Efficiency Spin-On Filter makes a big difference. With more than double the filtration surface area, it helps your transmission run cooler and shift smoother, even under stress. Whether you're hauling heavy loads through the mountains or pushing extra horsepower, this filter works hard behind the scenes to keep your fluid clean and your shifts responsive. It’s an easy upgrade that takes just minutes to install but delivers long-term benefits you’ll notice right away. PPE built this filter to handle the realities of hard use, so you can stop worrying about what’s happening inside your transmission and focus on the road ahead.

Engineered To Outperform The Factory Shorty Filter

The PPE 128059150 Spin-On Transmission Filter is a purpose-built upgrade for Allison 1000 and 2000 series transmissions, designed to exceed the capabilities of the OEM design. Inside, you'll find 2.72 times more filter media than the stock version, allowing significantly better fluid flow and debris capture. This high-capacity filter traps particles as small as 15 microns, compared to the 30-micron standard of factory filters. That finer filtration helps protect sensitive internal components, reducing wear and supporting longer transmission life. Better fluid quality also translates to smoother shifts and more consistent performance under load. The filter threads on easily in place of the original, fitting seamlessly on GM Silverado and Sierra 2500HD/3500HD models from 2001 to 2019 with the 6.6L Duramax. With durability and performance in mind, PPE created a true workhorse of a filter for trucks that don't back down.
