omg what a huge huge difference it makes for the 3.0 my engine runs smoother , sings at 4000 rpms and at 5000 rpms the pick up form it is way more than i thought it would be
so anybody thinking of doing this....you wont regret it

 

Nice. Roller rockers next!!!

 

ive heard that they always need to be adjusted , but i could be wrong

 

LoL mine just came in today! I'm waiting for my tuner to come in.

 

How much are they for a set and what are the downfalls? ive read a little bit about them but i guess i still dont fully understand. Ohh and can they be run without an a/c compressor and would i need a new serpentine belt?

 

dont need a full set, just get the crank pulley and a new belt. stuffforyourranger.com has everything you need....hit them up

 

and yes, the crank pulley does wake/smooth up the 3.0

 

what about the 4.0?

 

i have been running them for years with no complaints and nothing but praise

 

From what I hear the ud pulleys don't make as big of a difference on 4.0's or at least not worth the high cost for the small amount of power. But I could be wrong.

 

tax returns need to come NOW. i want to get a set lol
