4081 HP+ One-Piece pushrod set. For 580 cam

Designed for 1991 to 2003 Sportster XL models, these Feuling HP+ one-piece pushrods are the perfect match for Feuling 580 cams or other small base circle grinds. Sold as a kit, these rods are +.040 inches longer than stock to ensure correct valve-train geometry. They are constructed from 7/16-inch 4130 chromoly with a .165-inch wall thickness, offering much higher strength than standard adjustable pushrods. The solid construction eliminates flex and reduces harmonics, which is vital for maintaining valve lift at higher engine speeds. These fixed-length rods are heat-treated and finished in black oxide, providing a durable and reliable solution for your Sportster performance build.
