What is the purpose of titanium valve spring retainers? Cant I just use my stock ones with 105k miles? Can I use stock ones with CTR cams (with ITR springs)? Can I use stock ones with JUN 2 cams (with some beefy springs)?

 

i heard stock ones tend to break under high rpm applications....
Just what I have heard!

 

Im wondering if the retainers are needed because the springs are so much stronger, they can break the stock ones. As for the RPM, I plan on keeping the 8k redline.

 

That is exactly why they are used. The titanium springs may be just a little too stiff for stock retainers... they may work, but surely not as reliable. I don't see any reason to upgrade retainers ONLY, I don't think that was what you were saying though either.

 

itr cams you wont need to update your valve train, but if you use the jun cams you should use titanium retainers AND dual valve springs

 

I thought it was purely for weight reasons....titanium is actually not stronger than steel.

 

titanium or stainless steel upgrade the fricken valve train...

If the weight is too great, then it creates unnecessary stress due to inertia. A lighter retainer having less mass creates less stress upon itself and the rest of the valvetrain and thus is more resistant to breakage.
