Description

The Feuling Parts 4025 HP+ Lifters are a performance upgrade designed for XL Sportster and Buell models from 1991-1999. This enhanced oil flow contributes to cooler oil temperatures and significantly reduces wear, thereby extending the overall life of the valve train components. Installation is straightforward, as these lifters are designed as a direct, drop-in replacement for stock lifters. Sold as a pack of four, they are made in the USA. When used in conjunction with a Feuling oil pump, they are reported to further increase critical oil flow. A warning regarding Cancer and Reproductive Harm is included, directing consumers to www.P65Warnings.ca.gov.

MIA's Description

The Feuling Parts 4025 is a set of four performance full-travel hydraulic roller lifters designed as a drop-in replacement for stock lifters. They are CNC machined and precision ground in the USA. These lifters optimize oil flow to the top end, including valves, springs, rockers, shafts, and valve guides, promoting cooler oil and reduced wear. This extends the life of the top-end valve gear.
