Anyone have the insider tip on a good long lasting spring?I am running a 625 lift short duration LSr cam.Do I need $500 springs or are the $250 dollar set-up with cups and titanium retainers up to the task?Not a daily driver but a road tripper.Thanks in advance.

 

I see no need to go with the high dollar springkit as performance will be exactly the same out of the cheaper kits. Your cam will not challenge these dual kits at all so I think you would be fine.

 

The PRC .650 dual spring kit will work perfect in this application.
