Andrews, 91-03 XL adj. chromoly pushrod set

91-03 XL (NU)

Can be used with OEM hydraulic tappets or run as solids. Chromoly pushrods are thinner and have better flex resistancy than aluminum. Aluminum is lighter than chromoly and will reduce inertia mass. But for heavy duty service, like racing and/or high lift cams with high pressure springs it is still advised to run chromoly pushrods. Note: Must be used with multiple parts pushrod covers so pushrods can be adjusted. Note: See 906697 for aluminum pushrods.
