I am currently running JUN IIIs with JUN Valvesprings and crower retainers. Is there or are there any problems with crower retainers? Is there a big difference between JUN retainers and crower retainers?

 

anyone. A titanium retainer is a titanium retainer right?

 

same steup as me and i have been reving to 9200 for a long time know and everything thing is perfect

 

I have the same setup, but in a B16A motor. My car has 99k miles, more than 50k was with Crower Ti retainers.

No problems here.

tom fujita at portflow design pointed out to me that they are the lightest on the market..but because they have so little material that the structure itself can crack with stiff valve springs...yes...he did show me a set that had started to fail with cracks..
his design, jun's and others are a bit heavier...but are stronger...

for a street car that see ocassional high revs...i think the crowers will work fine with the jun springs..
