Right — this is the S&S Camshaft Inner Needle Bearing (1936–1999), a small but vital bit of engineering for Big Twin engines. The stock bearings in these motors have a rather poor reputation — they can wear out or even break, often at the least convenient moment.
This S&S bearing, however, is made to exceed OEM standards, with tighter tolerances and stronger materials. It keeps the camshaft running true, smooth, and free from the wobbly nonsense that leads to expensive repairs later on. In short: a modest upgrade that quietly prevents major disasters — exactly the sort of mechanical common sense I approve of.
Design & Quality Notes
Precision manufacture — made to tighter tolerances than many stock parts, ensuring a better “fit and forget” condition.
High strength materials — built to resist fatigue and handle the loading inside a cam chest.
OEM replacement for part number 9058 — so it slots into existing systems without Frankenstein modifications.
Fitment window — covers a long span (1936 to 1999) for Big Twin engines, making it broadly useful in vintage and classic restorations.
