I saw in a post in here that the comp springs ill be needing for the tr 224 cam are only good for 15000mi! Is this true?? If it is, which other springs should i get? I hope not but who knows. Please respond!!
Thanks,
Derek

 

918's will last a lot longer then that with that cam.

 

Good, I had just heard (read) this too. I guess they recomend changing every 15000 miles with a fast ramp cam with close to .600 lift?? How will I be able to tell when mine need changing?

 

I'd like as much info on this as possible also. I did a bunch of searching at LS1Tech a while back, and the concensus was that annual valve spring replacement was an expected maintenance for high lift, fast ramp cams.

 

Wonder whats considered high lift?

 

yeah this would be nice to know!

 

the 224 is a fast ramp cam..
I just had mine checked and they where still with in there limits..
have about 25,000 miles on them..

 

25K with a TR224 sounds pretty good to me....anybody else have any cam spec/mileage experience with the 918's?

 

Id run a dual Crane spring before I played with 918's.

 

bud, i think the biggest rool is in how hard you drive the truck. If you race every week, then of coarse the springs will weaken faster. I had 918's on my car for 2 years and about 20k miles... but i swapped those for duals now.

I think some have had as much as 30-40k on them, but it would be safe to swap them with anywhere from 15-25k on them. They might last forever, or one could go at 20k and cost you 4-6k in damage
