The FleetGuard Lube Spin-On Filter is the ultimate solution for your Kenworth, Thermo King, and Peterbilt lube filtration systems. Designed with advanced sludge-removal capabilities, this filter ensures extended service use and maximum engine performance. Featuring a Venturi nozzle, this filter creates a low-pressure zone that helps oil flow efficiently through the stacked-disc section. The nozzle diffuser maximizes the flow through the pleated stratapore media, ensuring minimum total-filter restriction. The lube combo spin-on filter combines full-flow and by-pass filtration into one single filter, developed to meet or exceed engine requirements. The Venturi combo's by-pass-stacked discs remove harmful sludge and allow the lube system to perform more effectively than full-flow only synthetic filters. Invest in the Spin-On Lube Filter for superior filtration and engine protection. Trust us to keep your engine running smoothly and efficiently. FleetPride is your First Click in Heavy Duty®.
