I'm not a salesman…nor do I attempt to persuade, but here’s some food for thought;
*The best lifters in existence for the most extreme applications do not use bushings.
*Bushings require far more oil supply and flow to prevent skidding.
*Rollers can survive and provide less friction with minimal oil supply.
*Rollers run cooler.
*Load moment on rollers are no different than bushings.
*It’s not the needle v/s bushing concept that prevents or promotes failure.
And finally……
*OEM manufactures do not use bushings. Manufacturing cost in a high production environment would be significantly less with bushings – add that up over millions of OEM lifters produced…..why wouldn’t they use them if they were better and cheaper to produce?
If the manufacturer has a design to cost initiative .....which I am sure they have had, then we can see the benefit. A cheaper alternative. An they haven't switched over. my
