I have a 5.3 LS4 and thought swapping in a cam shaft with new rods and springs. Would I need to get new lifters as well? I don't want to rip the whole top end apart if I don't have to.

 

you dont need too. my car has 105k miles on the stock lifters and trays and ive swapped cams twice. should i replace them? probably but if it aint broke im not going to fix it.

 

Thanks! anyone else swap their cam and not change lifters?

 

I did a can swap and didn't change my lifters or trays 2 months later cracked a lifter tray and the bearings on my lifter came out

 

Thanks for the input!!

 

Not a necessity unless one or more have been scored by oil starvation. The big thing with used lifters is not putting them into a different location on the same used camshaft. These parts have a wearing pattern, and if moved can cause increased wear rate. But if all rollers look good, reusing them should be fine.
