Lifter question

[Tn14outdoorsman]

I'm excited to be getting my truck back today. He used oem camshaft and lifters. Should the lifters be better than the ones that it had originally? Did Dodge update them since 2014 ?

Ive heard they did around 2016 i believe but ive talked to dealer techs and they tell me they changed nothing. Same part number same lifter

I'm hoping to drive this truck for many miles without any cam or lifter problems

Im hoping to drive mine till it rusts in half. Schaeffers 9000 5w20 is what im using to do it hopefully. Try redline 5w30 as that has well documented success with killing hemi tick on the syn thread

I'd like to hear from some that have had this cam and lifters replacement done and how their truck is running now

I am curious if anyone knows how much preload there is on the MDS lifters

This video has the lifters broke down and you can see the internal springs ,he doesn't measure the spring rate,but i don't think i've ever seen a spring rate ever listed for the internal spring,so what the lifter pre load by the pushrod is,might take some digging to find out.

@Tach_tech - if you're out there, would you comment, please? FCA change Hemi valve lifter vendor and design for 2017 model year?
