Fleetguard LF16035 Oil Filter
Updated June 24, 2026
The Fleetguard LF16035 is a heavy-duty spin-on oil filter designed for Dodge Ram 2500 and 3500 trucks equipped with Cummins 5.9L and 6.7L diesel engines. It is the Stratapore media upgrade of the earlier LF3972 filter, offering improved filtration efficiency (30 micron absolute) and a fluted shell design introduced for the 2003 model year Dodge Ram application. This filter is a direct replacement for the original equipment filter and is commonly used across model years 1989 through 2018.

Design and Filtration Technology
The LF16035 uses Fleetguard's Stratapore synthetic media, which provides 30 micron absolute filtration efficiency (TWA 100%). This media captures more contaminants than conventional cellulose filters while maintaining low flow restriction. The filter features a fluted outer shell that distinguishes it from the similar LF3894; this fluted design ensures proper clearance in the tight filter housing area of Dodge Ram trucks. The gasket and anti-drainback valve are engineered for reliable sealing and oil retention during engine shutdown.
Vehicle and Engine Compatibility
This filter is specifically engineered for Dodge Ram 2500 and 3500 trucks (and related chassis-cab models) powered by the Cummins 5.9L (359 cu in) and 6.7L (408 cu in) inline-six diesel engines. It covers model years from 1989 through 2018, including both 12-valve, 24-valve, and common-rail iterations. The LF16035 replaces the earlier LF3972 and is also cross-referenced with OEM numbers such as 42025883, 4920070, 57620, and 57620XE. It is not recommended for use with gasoline engines or other diesel platforms.
Installation and Replacement Notes
Installation follows standard spin-on filter procedure: lubricate the gasket with clean engine oil, hand-tighten until the gasket contacts the mounting base, then tighten an additional 3/4 to 1 turn. The filter uses a 1-16 UN-2B thread and does not require a standpipe. Always check for proper clearance after installation. Replacement intervals should follow the vehicle manufacturer's recommendations (typically every 7,500 to 15,000 miles depending on operating conditions). Dispose of used filters in accordance with local regulations.
