Harland Sharp rockers

[Moparmal]

I'm interested in the expected life span of Harland Sharp needle bearing rockers.

Can anyone provide feedback on there experiences re how long they've lasted, what spring pressures you ran and if you had any issues?

well sir the expectation is on what. on a street motor? I would think they would last for ever. I do know we ran them on all our dirt track motors running 7 to850 pounds of open psi. and never had a failure.but we ran 50wt.race oil. and if you have a problem with them you can send them back to be rebuilt.or at lest you used to.i don't know about now.Im sure there are others on here that can tell you more and if you here of any failures ask what oil they are running more than likly its split wt. oil.hope this helps

Thanks and I shoud of said, in a street application.

I'm mainly interested in the roller bearing durability, some folk reckon they should be avoided, but HS seem to have a great rep?
