ANDREWS, 91-03 XL NON-ADJ. CHROMOLY PUSHROD SET
Non adjustable fixed length pushrods, for use with OEM style hydraulic tappets only. Available in chromoly steel and aluminum. 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: See 906691 aluminum pushrods.
Fits: > 91-03 XL (NU)
