Good To Know

Q: Do I need to replace both bellows springs at the same time? A: Replacing springs in pairs helps keep valve actuation even across cylinders. Inspect each bellow and spring for wear before ordering.

Q: How do I know if my power valve bellow spring needs replacing? A: Weak tension, sticking valves, or a collapsed bellow usually point to a worn spring. Confirm the part matches your engine before install.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
