i'm starting this thread as a way of informing you guys with the 4cyl tacoma's that the pro comp 3 inch complete coil kit * was not designed for our trucks* they designed the kit for the V6 models of tacoma. they only used V6 carrying taco's to develop the kit.
apparently they knew this but, are continuing to sell and leave it up on there website in their configurator as a model specific choice for 2nd gen 4cyl tacoma's when in fact its not.
the spring rate for this kit is just over 720#'s the coils on my truck refuse to articulate in any way shape or form. also worth noting is the complete lack of down travel. both front and rear i achieved 4 3/8 inches of lift after 2 weeks and over 500 miles. the day of the instal the recorded measurment was 4.75 inches!!!!! so a fair warning is issued to all... this kit as per a pro comp tech was never intended for 4 cylinder tacomas.
on a side note if you have an arb bull bar the kit will begin to function properly but, a "HEAVY" plate steel bumper is what is needed and even then it will more than likely still yield more than the advertised 3 inches of lift. also it would be extremly wise to instal the differential drop with this kit i know some guy's will say to forget them and they do not do much but, i'm positive that if i did not install my diff drop i would have completely destroyed my diff. even though i had checked all this out with a pro comp technician & a 4wp's sales rep over the phone they said it would work fine. they also told me i would be able to retain my factory uca's lol well not at 4.75 inches of lift i ain't.
the company 4wp's needs to get their shit together and begin training their employees and making sure they know what they are selling. its unfortunate because the guys who are running this kit in their V6 tacoma's seem to like them. they just do not work properly on the 4 bangers at all
one more thing to consider for anyone purchasing this kit it rides very stiff due to the extremely high spring rate there is no way around this one.
