Anyone in the aftermarket offer these for the 4.0L?

 

505 Performance has them for the "bargain" price of $1225 for the kit (cam, lifters, timing chain, push-rods, and valve springs):

Add another $400 if you want roller-rockers to go with your roller-lifters:

From what I've heard/read 5.2L V8 roller-lifters will fit the 4.0L I6 but you'll still need a roller-cam for the 4.0L and none of those are cheap ($500+).

 

I got a bunch of hits with a google search. Here is the link> https://www.google.com/search?hl=en&...pe=&as_rights=

 

I take it those prices were for a Hyd Roller setup. Believe it or not but that was an item to check on for my upcoming engine build. This years build money has about come to an end and its only Feb. I will admit it is a very large project.

It would have a number of advantages for sure and not for race considerations either, nor RPM's. One thing I have always used with roller motors as all of them were mech. were titanium retainers even more weight lost. They do not cost that much additional.

My 4.0 will be a stock build but a very well built 4.0.

 

Thanks for the links.
