Feuling Motor Company 4072 HP+ One-Piece Pushrods for Harley Twin Cam 1999-2017

The Feuling HP+ 4072 pushrods are fixed-length, one-piece pushrods designed to maintain maximum cam and valve lift while reducing valvetrain harmonics and hydraulic lifter issues commonly associated with adjustable pushrods. These stock replacement length pushrods are designed to work with factory base circle camshaft dimensions, making them ideal for Harley-Davidson Twin Cam engines from 1999-2017.

Key Features:

• Fixed length, 4130 chromoly one-piece construction with swedged formed ends
• Heavy-duty 7/16" diameter tube with 0.165" wall thickness
• Heat-treated with black oxide finish for durability
• Compatible with Feuling 525, 543, and 574 cam grinds
• Also works with Feuling 594 cam grinds
• Made in the U.S.A.

The one-piece design provides superior reliability in the Twin Cam's 4-valve engine configuration, where one rocker arm activates two valve springs. This robust construction eliminates the weak points found in adjustable pushrods, ensuring consistent performance and longevity.
