Correct for the Willys L134 or F134 gear drive jeep engines. This is correct for the Willys CJ2A, CJ3A, M38, M38A1, and early CJ5. CAMSHAFT TIMING GEAR FOR WILLYS L134 OR F134. Not noisy. The good part is that you can more easily remove these gears in the future if needed without damaging them which is nearly impossible with the old fiber timing gears.
