Need assistance with Toytec Coil Over adjustment

Need assistance with Toytec Coil Over adjustment

Ok, well I am very new to lifts, and especially an adjustable lift.
I ordered the Toytec Coil Over kit (TTAFCS-6005)
http://toyteclifts.3dcartstores.com/ToyTec-Coil-Overs-FJ-03-UP-4Run-05-UP-Tacoma_p_13.html

I made no changes to the settings and installed the coil overs with no issues. Now I want to make some adjustments to the lift. I have both spanner wrenches and I do see where they go to make the adjustments; however, I do not understand the adjustment process.
I am using this picture as a reference

Since I am new to this please excuse my lack of knowledge and proper terms.
So what does the large (red arrow) adjustment do?
What does the small (yellow arrow) adjustment do?
Why two adjustment areas?
I did see somewhere that there should be a certain amount of threads to certain areas to set a specific height. So are we talking about area A, B, or C?
Based on this picture what is my current height set at?
What should it look like if I want to lower my lift by 1.5 inches?

I did a search on how to adjust the lift kit and did not turn up any helpful information so any help someone can provide would be appreciated.

 

I believe you are putting the spanner wrenches where the red arrow is pointing to raise/lower. Area B is the "thread count area" to approximate lift height. I believe the consensus is a 1/4'' of the spanner equates to 1/8'' of lift or similar?

I am not the expert on these coil overs so hopefully others will chime in.

I have never adjusted mine but keep in mind they come set at 2.5", so dropping it 1.5" will only net you a 1" lift. From what I recall, the adjustment is made at the large collar (red arrow). The smaller collar at the bottom is only used by the smaller spanner wrench for leverage if the large adjustment collar is difficult to turn. I highly recommend draw a line using a sharpie across the threads and adjustment collar so you know your starting point.(Just in case you need to re-correct the adjustment). I believe when you compress the spring, your lift increases. 1/4 turn of the wrench equals roughly 1/4-1/2" lift. PB Blaster on the threads may help make it easier but I think you need to drive it a few mos to see how much it settles before you start adjusting the height unless the truck is too nose high.

 

The red arrow is the adjustment collar. Adjust that collar to manipulate ride height. The small spanner will just hold the lower collar steady. The lower collar should not spin, it is just being held there by a retainer clip so you need to hold that lower collar still while you adjust the upper collar. Lift is roughly 2:1 meaning if you screw the upper collar up by 1/4", you'll effectively adjust your ride height by roughly 1/2". I'm not familiar with how many threads should be exposed to acheive which height but if the thread you're reading references exposed threads, that would be Area B. Area C will not change, it is a constant regardless of ride height.

 

I have these coils as well and I adjusted one of them this summer.

like posted above, you will be turning the large collar with the red arrow. use an allen wrench on the small collar with the yellow arrow to keep it stationary while you are turning the large collar. also, mark the threads on the coil with a sharpie so you know where to stop.

to get the spanner wrench around the large collar, I had to move the sway bar. I didn't have to take it all the way off... I just unbolted it from the frame and pushed it aside.

it takes ALOT of leverage to turn the collar. I put the end of the spanner wrench into a 4 foot length of pipe to get enough leverage. it also took a lot of turns of the wrench to move the collar to where I wanted it.

good luck

Guys, thanks so much for all the help. I will make the adjustments in the next week or so, once I am sure the suspension has settled.
