about how much are these kits and what all is involved in putting them in. my truck pulls hard till about 3k. then starts losing *** and i want it to pull longer. i have a buddy that can install it but would rather do it myself.

 

I believe its much the same as the 3k spring install.....PDR governor spring installation You should get a decent set of instructions, depending on where you get them from.

You also need to put in the HD valve springs.

 

The DYnomite Diesel Kit includes both 3K and 4K springs

Pretty easy. Just make sure to put the nuts on the same distance. Use a set of vernier calipers to measure the stud stick out.

4K is the same as a 3K with one extra spring in the pack.

And if you do it right, you'll be putting in 60# valve springs. Otherwise the valves will float at around 3800 RPM.

Good luck

 

if you have the 3K in already you can buy the conversion kit for cheap. post up a price request thread in the price request forum

 

they float at around 3200 rpm

 

that just answered my next question. i was not sure if i had to set valve springs. My truck will turn about 3600 rpm now but stats falling on its face around like 2900 rpm so i guess ill wait a lil before i decided to do this kit just yet.

 

4Ks pull harder down low...

It could be your timing im runnig 16* with my 4ks and my power falls off around 3100-3200. Ive heard you need more timing to have power 3k+

 

Do you have enough fuel for 4K?

 

oviusly he does with whats in his signature
