Can you list the benefits of upgrading these items? I would think that if you aren't planning on revving to 4200 rpm's, is there really a benefit?
Thanks!
Thanks!

Cool deal guys! Woli, I'll get you a call tomorrow!

Marine, The Benefit is generally for the higher boost and rpm trucks, Any thing over about 3500 is starting to put strain and exceeded wear on the factory parts! These are not required until 4,000+! At 4,000rpm or 45lbs+ the factory valve springs don't have enough seat pressure to keep the valves closed, secondly, The Push rods begin to deflect, causing a retard in timing and lower valve lifts! Lastly over time in High HP / High RPM / and High Boost Applications these items will fail!
Some folks have brought it to my attention theres a vendor speaking horribly of these springs and pushrods... This is why haisley, schieds, PDR, and most of the big name vendors carry them! Sometimes folks get upset when they cant carry the same brand due to loyalty issues!
But keep in mind, We still can get F1, and Diesel dynamics and Dynomite diesel!
